Abstract
INTRODUCTION Cardiovascular events resulting from volume overload are a primary cause of mortality in hemodialysis patients. Bioelectrical impedance analysis (BIA) is significantly valuable for assessing the volume status of hemodialysis (HD) patients. In this article, we explore the correlation between the volume index measured by BIA and the cardiac function index assessed by echocardiography (ECG) in HD patients. METHODS Between April and November 2018, we conducted a cross-sectional study involving randomly selected 126 maintenance HD patients. Comprehensive data on medical history and laboratory test results were collected. Subsequently, we investigated the correlation between volume indices measured by BIA and cardiac function parameters by ECG. RESULTS We discovered a significant correlation between the volume indices measured by BIA and various parameter of cardiac function. The Left Ventricular Hypertrophy (LVH) group exhibited higher levels of the percentage of Extracellular Water (ECW%) and the percentage of Total Body Water (TBW%) compared to the Non-LVH group. Extracellular Water (ECW) and Third Interstitial Fluid Volume (TSFV) were identified as independent risk factors for Left Ventricular Mass (LVM), and both demonstrated a high predictive value for LVM. ECW% emerged as an independent risk factor for the Left Ventricular Mass Index (LVMI), with a high predictive value for LVMI. CONCLUSION ECW and TSFV were found to be positively associated with cardiac function parameters in HD patients.

Abstract
Background: Recent studies have shown that the baseline values of absolute aortic root diameter (ARD) and indexed diameter are associated with all-cause mortality and cardiovascular events in the general population, even in the absence of aneurysmal aortic disease. However, there is limited available data on the association between ARD and prognosis in end-stage renal disease (ESRD) patients receiving maintenance hemodialysis (MHD). Accordingly, the purpose of this study is to investigate the predictive value of ARD for all-cause mortality and cardiovascular events in this specific population.Methods: ARD was measured by echocardiography at the level of the sinuses of Valsalva at end diastole and indexed to body surface area (BSA). The primary endpoint was all-cause mortality. The secondary endpoint was major adverse cardiovascular events (MACE), including cardiovascular mortality, myocardial infarction and stroke. Cox proportional hazards models were conducted to evaluate the association between baseline ARD/BSA and clinical outcomes.Results: A total of 391 patients were included in this study. The primary endpoint occurred in 95 (24.3%) patients while the secondary endpoint occurred in 71 (18.2%) patients. Multivariate Cox regression analysis showed that ARD/BSA was an independent prognostic factor for all-cause mortality (HR, per 1-SD increase, 1.403; 95% CI, 1.118-1.761; p = 0.003) as well as MACE (HR, per 1-SD increase, 1.356; 95% CI, 1.037-1.772; p = 0.026).Conclusions: Our results show that ARD/BSA is predictive of all-cause mortality and MACE in MHD patients with ESRD and support the view that assessment of ARD/BSA may refine risk stratification and preventive strategies in this population.

[PMID: 36690764 DOI: 10.1007/s00246-023-03104-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Accepted: 01/13/2023] [Indexed: 01/25/2023]
Abstract
Survival of patients after repair of coarctation of Aorta (CoA) has improved significantly over the decades, but patients have decreased life expectancy as compared to the general population. This has been attributed to increased hypertension, cerebrovascular disease, and coronary artery disease. There has also been an increasing concern of overweight and obesity in patients with adult congenital heart disease. While there have been studies looking at the impact of long-term hypertension on myocardial performance and outcomes in this population, this study aims to assess the impact of obesity in these patients on their myocardial performance. Ventriculo-arterial coupling is used as a measure of myocardial performance which reflects the interaction between cardiac contractility and arterial elastance. Patients after CoA repair are known to have hypertension affecting the arterial elastance. Obesity affects cardiac contractility as well. This study demonstrated that in a group of young patients after CoA repair, body mass index (BMI) has a relationship with left ventricular (LV) contractility and myocardial performance. This relationship was independent of blood pressure. BMI itself was not seen to affect the determinants of diastolic function in this study, suggesting that LV contractility may be affected before one can notice a change in the diastolic function secondary to BMI.

Prognostic value of extraaortic-valvular cardiac damage in patients with moderate aortic stenosis and reduced left ventricular ejection fraction. Echocardiography 2024; 41:e15892. [PMID: 39023286 DOI: 10.1111/echo.15892] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 06/26/2024] [Accepted: 07/07/2024] [Indexed: 07/20/2024] Open
Abstract
PURPOSE The extraaortic-valvular cardiac damage (EVCD) Stage has shown potential for risk stratification for patients with aortic stenosis (AS). This study aimed to examine the usefulness of the EVCD Stage in risk stratification of patients with moderate AS and reduced left ventricular ejection fraction (LVEF). METHODS Clinical data from patients with moderate AS (aortic valve area, .60-.85 cm2/m2; peak aortic valve velocity, 2.0-4.0 m/s) and reduced LVEF (LVEF 20%-50%) were analyzed during 2010-2019. Patients were categorized into three groups: EVCD Stages 1 (LV damage), 2 (left atrium and/or mitral valve damage), and 3/4 (pulmonary artery vasculature and/or tricuspid valve damage or right ventricular damage). The primary endpoint included a composite of cardiac death and heart failure hospitalization, with non-cardiac death as a competing risk. RESULTS The study included 130 patients (mean age 76.4 ± 6.8 years; 62.3% men). They were categorized into three groups: 26 (20.0%) in EVCD Stage 1, 66 (50.8%) in Stage 2, and 48 (29.2%) in Stage 3/4. The endpoint occurred in 54 (41.5%) patients during a median follow-up of 3.2 years (interquartile range, 1.4-5.1). Multivariate analysis indicated EVCD Stage 3/4 was significantly associated with the endpoint (hazard ratio 2.784; 95% confidence interval 1.197-6.476; P = .017) compared to Stage 1, while Stage 2 did not (hazard ratio 1.340; 95% confidence interval .577-3.115; P = .500). CONCLUSION The EVCD staging system may aid in the risk stratification of patients with moderate AS and reduced LVEF.

Time course of hypertension and myocardial dysfunction following anthracycline chemotherapy in pediatric patients. IJC HEART & VASCULATURE 2024; 53:101436. [PMID: 38872982 PMCID: PMC11169083 DOI: 10.1016/j.ijcha.2024.101436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 04/11/2024] [Accepted: 05/27/2024] [Indexed: 06/15/2024]
Abstract
Background Anthracyclines are associated with cardiac dysfunction. Little is known about the interplay of pre-existing hypertension and treatment response. We aimed to investigate the relationship between hypertension and the development of cancer therapy-related cardiac dysfunction (CTRCD) in pediatric patients treated with anthracycline chemotherapy. Methods Pediatric patients with cancer who received anthracycline chemotherapy from 2013 to 2021 were retrospectively included. Serial cardiac assessments were conducted during and after chemotherapy. The primary outcome was the development of CTRCD, classified as mild, moderate, or severe according to contemporary definitions. Results Among 190 patients undergoing anthracycline chemotherapy, 34 patients (17.9 %) had hypertension (24 patients Stage 1, and 10 patients Stage 2) at baseline evaluation. Patients underwent chemotherapy for a median of 234.4 days (interquartile range 127.8-690.3 days) and were subsequently followed up. Hypertension was frequent during follow-up 31.3 % (0-3 months), 15.8 % (3-6 months), 21.9 % (0.5-1 years), 24.7 % (1-2 years), 31.1 % (2-4 years) and 35.8 % (beyond 4 years) (P for trend < 0.001). Freedom from mild CTRCD at 5 years was 45.0 %, freedom from moderate CTRCD was 87.8 % at 5 years. Baseline hypertension did not increase the risk of mild (HR 0.77, 95 % CI: 0.41-1.42, P = 0.385) or moderate CTRCD (HR 0.62, 95 % CI: 0.14-2.72, P = 0.504). Patients with baseline hypertension showed different global longitudinal strain (P < 0.001) and LVEF (P < 0.001) patterns during follow-up. Conclusions Pediatric patients often develop CTRCD post-anthracycline chemotherapy. Those with pre-existing hypertension show a unique treatment response, despite no increased CTRCD risk, warranting further investigation.

Evaluation of myocardial work changes after lung resection-the significance of surgical approach: an echocardiographic comparison between VATS and thoracotomy. Gen Thorac Cardiovasc Surg 2024; 72:542-550. [PMID: 38253974 DOI: 10.1007/s11748-023-02005-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 12/20/2023] [Indexed: 01/24/2024]
Abstract
OBJECTIVE Considering the controversial benefits of video-assisted thoracoscopic surgery (VATS), we intended to evaluate the impact of surgical approach on cardiac function after lung resection using myocardial work analysis. METHODS Echocardiographic data of 48 patients (25 thoracotomy vs. 23 VATS) were retrospectively analyzed. All patients underwent transthoracic echocardiography (TTE) within 2 weeks before and after surgery, including two-dimensional speckle tracking and tissue Doppler imaging. RESULTS No notable changes in left ventricular (LV) function, assessed mainly using the LV global longitudinal strain (GLS), global myocardial work index (GMWI), and global work efficiency (GWE), were observed. Right ventricular (RV) TTE values, including tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (TASV), right ventricular global longitudinal strain (RVGLS), and RV free-wall GLS (RVFWGLS), indicated greater RV function impairment in the thoracotomy group than in the VATS group [TAPSE(mm) 17.90 ± 3.80 vs. 21.00 ± 3.48, p = 0.006; d = 0.84; TASV(cm/s): 12.40 ± 2.90 vs. 14.70 ± 2.40, p = 0.004, d = 0.86; RVGLS(%): - 16.00 ± 4.50 vs. - 19.40 ± 2.30, p = 0.012, d = 0.20; RVFWGLS(%): - 11.50 ± 8.50 vs. - 18.31 ± 5.40, p = 0.009, d = 0.59; respectively]. CONCLUSIONS Unlike RV function, LV function remained preserved after lung resection. The thoracotomy group exhibited greater RV function impairment than did the VATS group. Further studies should evaluate the long-term impact of surgical approach on cardiac function.

Application of apical myocardial perfusion quantitative analysis by contrast-enhanced ultrasound utilizing high-frequency linear probe. Echocardiography 2024; 41:e15886. [PMID: 39007877 DOI: 10.1111/echo.15886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 06/22/2024] [Accepted: 06/25/2024] [Indexed: 07/16/2024] Open
Abstract
BACKGROUND Due to insufficient near-field resolution and artifacts, it is challenging to evaluate the left ventricular apical perfusion with phased-array probes. By combining high-frequency linear probe and contrast-enhanced ultrasound (CEUS), imaging of apical myocardial perfusion could be improved. The study aims to evaluate the preliminary application of CEUS by high-frequency linear probes to assess the apical perfusion. METHODS The study enrolled retrospectively 91 patients to test the feasibility of the novel method. In protocol 1, patients were stratified into a group with left anterior descending artery (LAD) stenosis (N = 40) and a group without LAD stenosis or coronary artery disease (N = 41) based on the degree of coronary artery narrowing, quantified by >50% stenosis in coronary angiography. Receiver operating characteristics (ROC) analysis was performed to test the diagnostic value of perfusion parameters. In protocol 2, the reproducibility of high-frequency linear probe in apical perfusion analysis was compared with the conventional phased-array probe in 30 patients. RESULTS (1) The novel method is feasible in 81(89.01%) patients. (2) In protocol 1, to detect LAD stenosis, the best cut-off of β, T, A, and MBF were 10.32, 3.28, 9.39, and 4.99, respectively. Area under the curve of β, T, A, and MBF were .880, .881, .761, and .880, respectively. (3) In protocol 2, compared with phased-array probe, the quantitative analysis of high-frequency linear probe is of high reproducibility and could get good curve fitting (R2 = .29 vs. R2 = .71, P < .01). CONCLUSION Observation of apical perfusion using this method is feasible and quantitative analysis allows an accurate and convenient identification of LAD stenosis. This method provides an alternative for patients who have difficulties in visualizing the apical region with a phased-array probe.

Abstract
BACKGROUND The structural and functional characteristics of the heart in patients with diabetes mellitus (DM) and without myocardial infarction (MI) are not fully understood. METHODS We retrospectively analysed the data of patients with left ventricular ejection fraction (LVEF) ≥ 40% who underwent contrast-enhanced cardiac magnetic resonance imaging (CMR), which was also used to exclude MI, at two hospitals. Volumetric data and extracellular volume fraction (ECVf) of the myocardium evaluated using CMR were compared between patients with and without DM, and their association with diastolic function was evaluated. RESULTS Among 322 analysed patients, 53 had DM. CMR revealed that the left ventricular mass index (LVMi) and ECVf were increased while LVEF was decreased in patients with DM after adjusting for patient characteristics (all P < 0.05). A stronger positive correlation was observed between LVMi and the early diastolic transmitral flow velocity to early diastolic mitral annular velocity ratio (E/e') in patients with DM than in those without DM (correlation coefficient [R] = 0.46, p = 0.001; R = 0.15, p = 0.021, respectively; p for interaction = 0.011). ECVf correlated with E/e' only in patients with DM (R = 0.61, p = 0.004). CONCLUSIONS Patients with DM have increased LVMi and ECVf. Importantly, there was a difference between patients with and without DM in the relationship between these structural changes and E/e', with a stronger relationship in patients with DM. Furthermore, DM is associated with mildly reduced LVEF even in the absence of MI.

Abstract
BACKGROUND Anesthesiology experts advocate for formal education in maternal critical care, including the use of focused cardiac ultrasound (FCU) in high-acuity obstetric units. While benefits and feasibility of FCU performed by experts have been well documented, little evidence exists on the feasibility of FCU acquired by examiners with limited experience. The primary aim of this study was to assess how often echocardiographic images of sufficient quality to guide clinical decision-making were attained by trainees with limited experience performing FCU in term parturients undergoing cesarean delivery (CD). METHODS In this prospective cohort study, healthy term parturients (American Society of Anesthesiologists [ASA] ≤ 3, ≥37 weeks of gestation) with singleton pregnancy, body mass index (BMI) <40 kg/m 2 , and no history of congenital and acquired cardiac disease undergoing scheduled, elective CD were recruited by a trainee. After undergoing standardized training, including an 8-hour online E-learning module, a 1-day hands-on FCU course, and 20 to 30 supervised scans until the trainee was assessed competent in image acquisition, 8 trainees with limited FCU experience performed apical 4-chamber (A4CH), parasternal long-axis (PLAX), and short-axis (PSAX) view preoperatively after spinal anesthesia (SPA) and intraoperatively after neonatal delivery (ND). Obtained FCU images were graded 1 to 5 by 2 blinded instructors (1 = no image to 5 = perfect image obtainable; ≥3 defined as image quality sufficient for clinical decision-making). RESULTS Following the screening of 95 women, 8 trainees with limited FCU experience each performed a median of 5 [3-8] FCUs in a total of 64 women. Images of sufficient quality were obtainable in 61 (95.3 %) and 57 (89.1 %) of women after SPA and ND, respectively. FCU images of perfect image quality were obtainable in 9 (14.1 %) and 7 (10.9 %) women preoperatively after SPA and intraoperatively after ND, respectively. A PLAX, PSAX, and A4CH view with grade ≥3 was obtained in 53 (82.8 %), 58 (90.6 %) and 40 (62.5 %) of women preoperatively after SPA and in 50 (78.1 %), 49 (76.6 %), and 29 (45.3 %) of women intraoperatively after ND. Left ventricular function could be assessed in 39 of 40 women (97.5 %) preoperatively after SPA and 39 of 40 (97.5%) intraoperatively after ND. Right ventricular function could be assessed in 31 of 40 (77.5 %) after SPA and in 23 of 40 (59%) after ND. We observed a difference in image grading between different trainees in the AP4CH-view ( P = .0001). No difference in image grading was found between preoperative and intraoperative FCUs. CONCLUSIONS FCU is feasible in the parturient undergoing CD and images of sufficient quality for clinical decision-making were obtained by trainees with limited experience in almost all parturients. Image acquisition and quality in the A4CH view may be impacted by the individual trainee performing the FCU.

Huang HC, Chien KL, Liu YB. Outcomes with T-wave discordance of left bundle branch block and preserved or mildly reduced ejection fraction. ESC Heart Fail 2024; 11:2148-2158. [PMID: 38607371 DOI: 10.1002/ehf2.14764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 01/25/2024] [Accepted: 03/06/2024] [Indexed: 04/13/2024] Open
Abstract
AIMS Left bundle branch block (LBBB) is associated with an increased risk of adverse outcomes for patients with heart failure. The prognosis of LBBB in patients with a preserved ejection fraction (EF) remains controversial. This study investigated the predictive value of T-wave discordance for the prognosis of patients with LBBB and preserved or mildly reduced EF. METHODS AND RESULTS We enrolled 707 patients with complete LBBB and left ventricular (LV) EF ≥ 40% observed using electrocardiograms (ECGs) and echocardiograms between January 2010 and December 2018. Their serial ECGs were reviewed during the follow-up period. The T-wave pattern was classified as discordant LBBB (dLBBB) or concordant LBBB (cLBBB) according to the 12-lead ECG T-wave morphology. The primary outcome was the composite of cardiovascular death or hospitalization for heart failure during a median follow-up period of 3.1 years. A multivariable Cox regression analysis was used to evaluate the independent predictors of the primary outcome. Patients with dLBBB had more comorbidities, a higher heart rate, a longer QRS and QTc duration, a larger LV end-systolic volume and left atrial dimension, a lower LVEF, and a higher mitral E/A ratio and E/e', compared with those with cLBBB. Older age [hazard ratio (HR) = 1.023, 95% confidence interval (CI) = 1.001-1.046, P = 0.023], history of heart failure (HR = 2.440, 95% CI = 1.524-3.905, P = 0.001), chronic kidney disease (HR = 1.917, 95% CI = 1.182-3.110, P = 0.008), larger LV end-systolic volume (HR = 1.046, 95% CI = 1.017-1.075, P = 0.002), lower LVEF (HR = 0.916, 95% CI = 0.885-0.948, P = 0.001), and presence of dLBBB (HR = 1.63, 95% CI = 1.011-2.628, P = 0.032) were independent predictors of the primary outcome in patients with LBBB and LVEF ≥ 40%. The discordant or concordant T-wave morphology of LBBB could transform from one subtype to the other in up to 23% of the study population during the follow-up period, and individuals with persistent or transformed dLBBB faced an increased risk of cardiovascular death or non-fatal heart failure hospitalization. CONCLUSIONS In patients with LBBB and EF ≥ 40%, dLBBB serves as an independent predictor of a higher risk of cardiovascular death or non-fatal heart failure hospitalization.

Abstract
BACKGROUND This study aimed to evaluate associations between echocardiography markers and mortality in patients with type 2 diabetes mellitus (T2DM). METHODS Diabetes Care Management Program database of a medical center was used, including 5612 patients with T2DM aged 30 years and older and who underwent echocardiography assessment between 2001 and 2021. Cox proportional hazard regression models were used to evaluate associations of echocardiography abnormalities with all-cause and expanded cardiovascular disease (CVD) mortality. RESULTS During a mean follow-up of 5.8 years, 1273 patients died. Hazard ratios (95% confidence intervals) of all-cause mortality for each standard deviation increase were presented for the cardiac systolic function indicator of left ventricular ejection fraction (0.77, 0.73-0.81), cardiac structural parameters of left ventricular mass index (1.25, 1.19-1.31) and left atrial volume index (1.31, 1.25-1.37), and cardiac diastolic function of E/A ratio (1.10, 1.07-1.13), E/e' ratio (1.37, 1.30-1.45), and TR velocity (1.25, 1.18-1.32); meanwhile, the values of expanded CVD mortality included left ventricular ejection fraction (0.67, 0.62-0.72), left ventricular mass index (1.35, 1.25-1.45), left atrial volume index (1.40, 1.31-1.50), E/A ratio (1.12, 1.08-1.16), E/e' ratio (1.57, 1.46-1.69), and TR velocity (1.29, 1.19-1.39), respectively. CONCLUSIONS Cardiac systolic function indicator of left ventricular ejection fraction, cardiac structural parameters of left ventricular mass index and left atrial volume index, and cardiac diastolic function indicators of E/A ratio, E/e' ratio, and TR velocity are associated with all-cause and expanded CVD mortality in patients with T2DM.

Abstract
AIMS Women with congenital heart disease (CHD) are at risk of pregnancy-related adverse outcomes (PRAO). The purpose of this study was to assess temporal changes in cardiac structure and function (cardiac remodelling) during pregnancy, and the association with PRAO in women with CHD. METHODS AND RESULTS Retrospective study of pregnant women with CHD and serial echocardiograms (2003-2021). Cardiac structure and function were assessed at pre-specified time points: prepregnancy, early pregnancy, late pregnancy, and postnatal period. PRAO was defined as the composite of maternal cardiovascular, obstetric, and neonatal complications. The study comprised 81 women with CHD (age, 29 ± 5 years). Compared to the baseline echocardiogram, there was a relative increase in right ventricular systolic pressure (RVSP) (relative change 13 ± 5%, P < 0.001, in early pregnancy; and 18 ± 5%, P < 0.001, in late pregnancy). There was a relative decrease in right ventricle free wall strain (RVFWS) (relative change -11 ± 3%, P < 0.001, in late pregnancy; and -11 ± 4%, P = 0.003, in postnatal period), and a relative decrease in RVFWS/RVSP (relative change, -10 ± 5%, P = 0.02 in early pregnancy, -26 ± 7%, P < 0.001, in late pregnancy, and -14 ± 5%, P < 0.001, in postnatal period). Baseline right ventricular to pulmonary arterial (RV-PA) coupling, and temporal change in RV-PA coupling were associated with PRAO, after adjustment for maternal age and severity of cardiovascular disease. CONCLUSION Women with CHD had a temporal decrease in RV systolic function and RV-PA coupling, and these changes were associated with PRAO. Further studies are required to delineate the aetiology of deterioration in RV-PA coupling during pregnancy, and the long-term implications of right heart dysfunction observed in the postnatal period.

Prevalence, Incidence, and Outcomes of Diastolic Dysfunction in Isolated Tricuspid Regurgitation: Perhaps Not Really "Isolated"? JACC Cardiovasc Imaging 2024:S1936-878X(24)00231-6.

Abstract
BACKGROUND In the absence of left-sided cardiac/pulmonary disease, functional tricuspid regurgitation (FTR) is referred to as isolated or idiopathic. Relationships between left ventricular diastolic dysfunction (DD) and FTR remain unknown. OBJECTIVES The purpose of this study was to investigate the prevalence, incidence, and outcome of DD in patients with idiopathic FTR. METHODS Adults without structural heart disease were identified. Severe DD was defined by ≥3 of 4 abnormal DD parameters (medial e', medial E/e', TR velocity, left atrial volume index) and ≥ moderate DD by ≥2. Propensity-score matching was performed (3:1) between each less-than-severe TR group and severe TR based on age, sex, body mass index, and comorbidities. RESULTS Among 30,428 patients, FTR was absent in 73%, mild in 22%, moderate in 4%, and severe in 0.4%. In the propensity-matched sample, severe DD was present in 2%, 6%, 9%, and 13% patients, and ≥ moderate DD in 11%, 18%, 28%, and 48%, respectively (P < 0.001). The probability of heart failure with preserved ejection fraction using the H2FPEF score increased with increasing FTR (median 29.7%, 45.5%, 61.4%, and 88.7%, respectively), as did the prevalence of impaired left atrial strain <24% (35%, 48%, and 69% in mild, moderate, and severe TR). Incident severe and ≥ moderate DD developed more frequently with increasing FTR (HR: 8.45 [95% CI: 2.60-27.50] and HR: 2.82 [95% CI: 1.40-5.69], respectively for ≥ moderate vs no FTR) over a median of 3.0 years. Findings were confirmed in patients without lung disease or right ventricular enlargement. Over a median of 5.0 years, patients with ≥ moderate FTR and DD had the greatest risk of worse outcomes (multivariable P < 0.001). The association between TR and adverse outcomes was significantly diminished in the absence of DD. CONCLUSIONS Diastolic dysfunction, increased heart failure with preserved ejection fraction probability, and impaired left atrial strain are commonly present in patients with idiopathic FTR, suggesting that the latter may not be truly isolated. Patients with FTR without DD or heart failure are at increased risk of incident DD. Patients with FTR and DD display worse outcomes.

Abstract
Development of ventricular failure and pulmonary edema is associated with a worse prognosis in ST-elevation myocardial infarction (STEMI). We aimed to evaluate the prognostic ability of a novel classification combining lung ultrasound (LUS) and left ventricular outflow tract (LVOT) velocity time integral (VTI) in patients with STEMI. LUS and LVOT-VTI were performed within 24 h of admission in STEMI patients. A LUS combined with LVOT-VTI (LUV) classification was developed based on LUS with < or ≥ 3 positive zone scans, combined with LVOT-VTI > or ≤ 14. Patients were classified as A (< 3zones/ > 14 cm VTI), B (≥ 3zones/ > 14 cm VTI), C (< 3zones/ ≤ 14 cm VTI) and D (≥ 3zones/ ≤ 14 cm VTI). Primary outcome was occurrence of in-hospital mortality. Development of cardiogenic shock (CS) within 24 h was also assessed. A total of 308 patients were included. Overall in-hospital mortality was 8.8%, while mortality for LUV A, B, C, and D was 0%, 3%, 12%, and 45%, respectively. The area under the curve (AUC) for predicting in-hospital mortality was 0.915. Moreover, after exclusion of patients admitted in Killip IV, at each increasing degree of LUV, a higher proportion of patients developed CS within 24 h: LUV A = 0.0%, LUV B 5%, LUV C = 12.5% and LUV D = 30.8% (p < 0.0001). The AUC for predicting CS was 0.908 (p < 0.001). In a cohort of STEMI patients, LUV provided to be an excellent method for prediction of in-hospital mortality and development of CS. LUV classification is a fast, non-invasive and very user-friendly ultrasonographic evaluation method to stratify the risk of mortality and CS.

Abstract
BACKGROUND Heart failure (HF) is becoming a growing public health concern. Diagnostic tests for determining the severity of HF often come with high costs and require specialized expertise, which makes it difficult to assess HF severity, especially in low-income countries or at primary healthcare facilities. Recently, red blood cell distribution width (RDW) has emerged as a promising, easily accessible marker associated with HF severity. The study aimed to assess changes in RDW levels in HF patients and the diagnostic value of RDW in detecting acute heart failure (AHF) among HF patients. METHODS We conducted a cross-sectional examination involving 351 participants divided into HF and non-HF cohorts. HF was defined and categorized according to the diagnostic and treatment guidelines for AHF and chronic heart failure (CHF) set forth by the European Society of Cardiology (2021). Univariate and multivariate analysis of factors associated with AHF was performed. RESULTS The study revealed that HF patients displayed higher median RDW levels (14.90% [13.70-17.00]) compared to non-HF individuals (13.00% [12.23-13.78]). RDW was notably elevated in HF patients with left ventricular ejection fraction < 50% compared to those with left ventricular ejection fraction ≥ 50%. ROC curve analysis of RDW for AHF detection identified a cutoff value of 13.85%, with a sensitivity of 86.05% and specificity of 47.18%, statistically significant at p < 0.001. RDW > 13.85% was identified as an independent risk factor for AHF in patients with HF, with odds ratios of 2.644 (95% CI, 1.190-5.875; p = 0.017). CONCLUSION The study revealed significant RDW variations in patients with CHF and AHF compared to the control group. These findings suggest that RDW could be a biomarker for detecting HF severity.

Differences in Right Heart Function After Pulmonary Valve Replacement in Patients With Pulmonary Valve Stenosis Versus Tetralogy of Fallot. J Am Heart Assoc 2024; 13:e034833. [PMID: 38958134 DOI: 10.1161/jaha.124.034833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 06/06/2024] [Indexed: 07/04/2024]
Abstract
BACKGROUND There are limited data about the impact of timing of pulmonary valve replacement (PVR) on right heart reverse remodeling in patients with pulmonary regurgitation following intervention for isolated pulmonary valve stenosis (PS). This study compared differences in postprocedural right heart reverse remodeling after early versus late PVR (defined as PVR before versus after attainment of the conservative consensus criteria proposed by Bokma et al, 2018) in patients with prior intervention for PS, using patients with tetralogy of Fallot as the reference group. METHOD AND RESULTS Right atrial reservoir strain and right ventricular free wall strain was measured at baseline, 1 and 3 years after PVR. There were 114 patients with PS (early PVR, 87 [76%]; late PVR, 27 [24%]) and 291 patients with tetralogy of Fallot (early PVR, 197 [67%]; late PVR, 96 [33%]). The PS group had greater improvement in right atrial reservoir strain at 1 year (12%±4% versus 8%±4%; P<0.001) and 3 years (15%±6% versus 9%±6%; P<0.001), and a greater improvement in right ventricular free wall strain at 1 year (12%±4% versus 7%±3%, P=0.008) and 3-years (16%±6% versus 12%±5%; P=0.01) after PVR compared with the tetralogy of Fallot group. There was no difference in right heart reverse remodeling between patients who underwent early versus later PVR within the PS group. In contrast, late PVR was associated with less right heart reverse remodeling within the tetralogy of Fallot group. CONCLUSIONS These data suggest that patients with palliated PS presenting pulmonary regurgitation have a more benign clinical course, and hence delaying PVR in this population may be appropriate.

Abstract
The goal of this study was to determine the potential for right ventricular (RV) and left ventricular (LV) strain to predict cardiopulmonary complications of COVID-19. We identified 276 patients with COVID-19 who underwent transthoracic echocardiography within 30 days of COVID-19 diagnosis at our institution. Patients were excluded if they had a history of any primary outcomes before COVID-19 diagnosis or insufficient imaging. LV global longitudinal strain (GLS) and RV GLS were obtained using 2-dimensional speckle-tracking echocardiography. Primary outcomes were death, pulmonary embolism, congestive heart failure (CHF), cardiomyopathy, pulmonary fibrosis, pulmonary hypertension, acute respiratory distress syndrome (ARDS), and myocardial infarction (MI) occurring after COVID-19 diagnosis. In the final analysis of 163 patients, mean RV GLS and LV GLS were reduced, and 43.6% developed at least one primary outcome. There were significant differences in LV GLS distribution in terms of CHF, cardiomyopathy, and MI in bivariate analysis. However, LV GLS was not significantly associated with CHF after adjusting for LV ejection fraction and RV fractional area change, nor with MI after adjusting for troponin T. RV GLS was significantly associated with ARDS after adjusting for other variables. In the risk stratification of patients with COVID-19, strain imaging can provide incremental prognostic information, as worsened RV GLS is associated with the development of ARDS.

Abstract
AIMS There are similarities in the pathogenesis of cardiac remodelling and dysfunction in heart failure with preserved ejection fraction (HFpEF) and coarctation of aorta (COA). We hypothesized that clinical HFpEF would be highly prevalent in adults with COA, and that the presence of HFpEF would increase the risk of mortality in this population. The aim of this study was to define the clinical features, haemodynamics, and prognostic implications of HFpEF in COA. METHODS AND RESULTS Consecutive adults with repaired COA that underwent right heart catheterization were identified retrospectively. HFpEF was defined as heart failure symptoms (exertional dyspnoea or fatigue), preserved left ventricular ejection fraction ≥50%, and pulmonary artery wedge pressure at rest >15 mmHg. Of 99 COA patients, 32 (32%) had HFpEF. The correlates of HFpEF were obesity (adjusted odds ratio [OR] 4.15, 95% confidence interval [CI] 1.31-13.2), atrial fibrillation (adjusted OR 3.13, 95% CI 1.00-10.7), total arterial compliance index (adjusted OR 0.12, 95% CI 0.06-0.41 per 1 ml/mmHg*m2), and pulmonary artery compliance index (adjusted OR 0.36, 95% CI 0.15-0.56 per 1 ml/mmHg*m2). Of 99 patients, 24 (24%) died and 5 (5%) underwent heart transplant. The 10-year cumulative incidence of death/transplant was higher in COA patients with HFpEF compared with patients without HFpEF (39% vs. 12%, p = 0.001). The presence of HFpEF was associated with increased risk of death/transplant (adjusted hazard ratio 1.68, 95% CI 1.16-3.11). CONCLUSIONS Heart failure with preserved ejection fraction is common in adults with COA and is associated with greater risk of death/transplant, emphasizing a pressing need for interventions to prevent and treat HFpEF in COA.

Patterns of atrial fibrillation, relevant cardiac structural and functional changes predict functional and cognitive outcomes in patients with ischemic stroke and atrial fibrillation. Int J Cardiol 2024; 407:131966. [PMID: 38490273 DOI: 10.1016/j.ijcard.2024.131966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 02/22/2024] [Accepted: 03/11/2024] [Indexed: 03/17/2024]
Abstract
BACKGROUND Atrial fibrillation (AF) pattern, relevant cardiac changes are important predictors of outcomes in AF, but their impact on patients with ischemic stroke and AF remained unclear. We aimed to explore the impact of AF patterns, cardiac structural and functional markers on long-term functional and cognitive outcomes in ischemic stroke patients with AF. METHODS Ischemic stroke patients diagnosed with AF were enrolled in this retrospective cohort study. AF pattern was defined by both traditional and novel classification, in which patients were divided into AF diagnosed after stroke (AFDAS) and known before stroke (KAF). Left atrial (LA) diameter, left ventricular ejection fraction (LVEF), natriuretic peptide (BNP) and cardiac troponin (cTnI) were dichotomized according to the median value. Outcomes include poor functional outcome and cognitive impairment at the 1-year follow-up. Multivariable logistic regression was performed to validate the association between AF pattern, parameters of cardiac change and functional and cognitive outcome. RESULTS A total of 377 patients were included. Non-paroxysmal AF patients had a higher risk of poor functional outcome (OR = 3.59, P < 0.0001) and cognitive impairment (OR = 2.38, P = 0.019) than paroxysmal AF patients, while there were no differences between AFDAS and KAF. Lower LVEF (OR = 1.83, P = 0.045) and higher BNP (OR = 2.66, P = 0.001) were associated with poor functional outcome. Lower LVEF (OR = 2.86, P = 0.004), higher LA diameter (OR = 2.72, P = 0.008) and BNP (OR = 2.31, P = 0.023) were associated with cognitive impairment. CONCLUSIONS AF type and related cardiac markers can serve as predictors for poor functional and cognitive outcomes. Comprehensive cardiac assessment and monitoring should be strengthened after stroke.

Abstract
BACKGROUND Enzyme replacement therapy (ERT) may halt or attenuate disease progression in patients with Anderson-Fabry disease (AFD). However, whether left ventricular hypertrophy (LVH) can be prevented by early therapy or may still progress despite ERT over a long-term follow-up is still unclear. METHODS Consecutive patients with AFD from the Independent Swiss-Fabry Cohort receiving ERT who were at least followed up for 5 years were included. Cardiac progression was defined as an increase of >10 g/m2 in left ventricular mass index (LVMI) between the first and the last available follow-up transthoracic echocardiography. RESULTS 60 patients (35 (23-48) years, 39 (65%) men) were followed up for 10.5 (7.2-12.2) years. 22 had LVH at ERT start (LVMI of 150±38 g/m2). During follow-up, 22 (36%, 34±15 years) had LVMI progression of 12.1 (7-17.6) g/m2 per 100 patient-years, of these 7 (11%, 29±13 years) with no LVH at baseline. Three of them progressed to LVH. LVMI progression occurred mostly in men (17 of 39 (43%) vs 5 of 21 (24%), p<0.01) and after the age of 30 years (17 of 22 (77%)). LVH at ERT start was associated with LVMI progression (OR 1.3, 95% CI 1.1 to 2.6; p=0.02). A total of 19 (31%) patients experienced a major AFD-related event. They were predominantly men (17 of 19, 89%), older (45±11 vs 32±9 years) with baseline LVH (12 of 19, 63%), and 10 of 19 (52%) presented with LVMI progression. CONCLUSIONS Over a median follow-up of >10 years under ERT, 36% of the patients still had LVMI cardiac progression, and 32%, predominantly older men, experienced major AFD-related events. LVH at treatment initiation was a strong predictor of LVMI progression and adverse events on ERT.

Abstract
BACKGROUND Infantile hypertrophic cardiomyopathy (HCM) is a heterogeneous disorder. Apart from registries in high-income nations, there is a shortage of data on the aetiological basis of infantile HCM in low- and middle-income nations. This study attempts to characterise the phenotypic expression, genetic architecture and short-term clinical outcomes of infantile HCM from a South Asian tertiary referral centre. METHODS This study includes all infants from the Amrita HCM cohort between January 2011 and July 2021. Clinical history, ECG, echocardiographic data, and genetic analyses were evaluated. RESULTS 34 patients with infantile HCM were diagnosed at a median age of 3.7 months (IQR 1-6 months). Underlying aetiologies were RASopathy (n=13; 38%), non-syndromic (n=12; 35%) and inborn errors of metabolism (n=9; 27%). Genetic analysis was done in 20 patients (59%) with a yield of 90%. Clinical presentation included failure to thrive (n=29; 85%), dyspnoea on exertion (n=23; 68%) and clinical heart failure (n=24; 71%). Echo showed concentric left ventricular hypertrophy in 22 patients (65%), obstructive HCM in 11 patients (32%) and left ventricular systolic dysfunction in 6 patients (18%). The mortality rate was 10.0 deaths per 100 patient years over a median follow-up period of 3.1 years. The main risk markers for mortality were the age at diagnosis, gender and concentric Left ventricular hypertrophy. CONCLUSIONS This cohort demonstrates the morphological, functional and genetical heterogeneity of infantile HCM, enunciating the need for integration of cardiology, metabolic and genetic services to achieve optimum outcomes in these patients.

Abstract
BACKGROUND Type 2 diabetes (T2D) is a frequent comorbidity encountered in patients with severe aortic stenosis (AS), leading to an adverse left ventricular (LV) remodeling and dysfunction. Metabolic alterations have been suggested as contributors of the deleterious effect of T2D on LV remodeling and function in patients with severe AS, but so far, the underlying mechanisms remain unclear. Mitochondria play a central role in the regulation of cardiac energy metabolism. OBJECTIVES We aimed to explore the mitochondrial alterations associated with the deleterious effect of T2D on LV remodeling and function in patients with AS, preserved ejection fraction, and no additional heart disease. METHODS We combined an in-depth clinical, biological and echocardiography phenotype of patients with severe AS, with (n = 34) or without (n = 50) T2D, referred for a valve replacement, with transcriptomic and histological analyses of an intra-operative myocardial LV biopsy. RESULTS T2D patients had similar AS severity but displayed worse cardiac remodeling, systolic and diastolic function than non-diabetics. RNAseq analysis identified 1029 significantly differentially expressed genes. Functional enrichment analysis revealed several T2D-specific upregulated pathways despite comorbidity adjustment, gathering regulation of inflammation, extracellular matrix organization, endothelial function/angiogenesis, and adaptation to cardiac hypertrophy. Downregulated gene sets independently associated with T2D were related to mitochondrial respiratory chain organization/function and mitochondrial organization. Generation of causal networks suggested a reduced Ca2+ signaling up to the mitochondria, with the measured gene remodeling of the mitochondrial Ca2+ uniporter in favor of enhanced uptake. Histological analyses supported a greater cardiomyocyte hypertrophy and a decreased proximity between the mitochondrial VDAC porin and the reticular IP3-receptor in T2D. CONCLUSIONS Our data support a crucial role for mitochondrial Ca2+ signaling in T2D-induced cardiac dysfunction in severe AS patients, from a structural reticulum-mitochondria Ca2+ uncoupling to a mitochondrial gene remodeling. Thus, our findings open a new therapeutic avenue to be tested in animal models and further human cardiac biopsies in order to propose new treatments for T2D patients suffering from AS.

Abstract
This research aimed to explore whether high-intensity focused ultrasound (HIFU) could conduct pulmonary artery denervation (PADN). HIFU was performed in pulmonary arteries of 6 normotensive rabbits at dose of 250W, 6 times for each rabbit, and an additional 6 rabbits served as controls. Then ATEPH was induced in both groups by intravenous infusion of autogeneic thrombus. Hemodynamics and ultrasonography parameters were measured by right heart catheter and echocardiography pre- and post-establishment of ATEPH models in both groups. Histological analysis and immunohistochemistry of tyrosine hydroxylase (TH) were also performed. After PADN procedures, 5 rabbits were successfully conducted PADN, of which ablation zone was also observed in right auricle or right lung in 4 rabbits. Ablation zone was detected only in right lung in 1 rabbit. Compared with control group, milder right heart hemodynamic changes were found in PADN group, accompanied by improved ultrasound parameters in PADN group. HIFU can acutly damage SNs around pulmonary artery successfully, which may be a new choice to conduct PADN. However, the accuracy of HIFU with PADN needs to be improved.

Abstract
BACKGROUND Wild-type transthyretin amyloid (ATTRwt) cardiomyopathy is increasingly recognized in the development of heart failure. The link between cardiac performance, hemodynamics, and mitochondrial function in disease stages of ATTRwt has not previously been studied but may provide new insights into the pathophysiology and clinical performance of the patients. METHODS AND RESULTS The study investigated 47 patients diagnosed with ATTRwt at Aarhus University Hospital, Denmark. Patients were stratified according to the disease stages of the National Amyloidosis Centre (NAC) as NAC I with low levels of NT-proBNP (N-terminal pro-B-type natriuretic peptide) (NAC I-L, n=14), NAC I with high levels NT-proBNP (NAC I-H, n=20), and NAC II-III (n=13). Exercise testing with simultaneous right heart catheterization was performed in all patients. Endomyocardial biopsies were collected from the patients and the mitochondrial oxidative phosphorylation capacity was assessed. All NAC disease groups, even in the NAC I-L group, a significant abnormal increase in biventricular filling pressures were noted during exercise while the filling pressures was normal or near normal at rest. The inotropic response to exercise was reduced with diminished increase in cardiac output which was significantly more pronounced in the NAC I-H (Diff. -2.4, 95% CI (-4.2: -0.7), P=0.00) and the NAC II-III group (Diff: -3.1 L/min, 95% CI (-5.2: -1.1), P=0.00) compared with the NAC I-L group. The pulmonary artery wedge pressure to cardiac output ratio at peak exercise was significantly different between NAC I-L and NAC II-III (Diff: 1.6 mm Hg*min/L, 95% CI (0.01:3.3, P=0.04)). Patients with ATTRwt had a reduced oxidative phosphorylation capacity which correlated to left ventricular mass but not to cardiac output capacity. CONCLUSIONS An abnormal restrictive left ventricle and right ventricle response to exercise was demonstrated, even present in patients with early-stage ATTRwt. In more advanced disease stages a progressive impairment of the pressure-flow relationship was noted. The myocyte energetics is deranged but not associated to the contractile reserve or restrictive filling characteristics in ATTRwt.

Secondary tricuspid regurgitation: incidence, types, and outcomes in atrial fibrillation vs. sinus rhythm. Eur Heart J 2024:ehae346. [PMID: 38953772 DOI: 10.1093/eurheartj/ehae346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 01/16/2024] [Accepted: 05/16/2024] [Indexed: 07/04/2024] Open
Abstract
BACKGROUND AND AIMS Incidence and types of secondary tricuspid regurgitation (TR) are not well defined in atrial fibrillation (AFib) and sinus rhythm (SR). Atrial secondary TR (A-STR) is associated with pre-existing AFib; however, close to 50% of patients with A-STR do not have AFib. The aim of this study was to assess incidence, types, and outcomes of ≥ moderate TR in AFib vs. SR. METHODS Adults with and without new-onset AFib without structural heart disease or ≥ moderate TR at baseline were followed for the development of ≥ moderate TR. Tricuspid regurgitation types were pacemaker, left-sided valve disease, left ventricular (LV) dysfunction, pulmonary hypertension (PH), isolated ventricular, and A-STR. RESULTS Among 1359 patients with AFib and 20 438 in SR, 109 and 378 patients developed ≥ moderate TR, respectively. The individual types of TR occurred more frequently in AFib related to the higher pacemaker implantation rates (1.12 vs. 0.19 per 100 person-years, P < .001), larger right atrial size (median 78 vs. 53 mL, P < .001), and higher pulmonary pressures (median 30 vs. 28 mmHg, P < .001). The most common TR types irrespective of rhythm were LV dysfunction-TR and A-STR. Among patients in SR, those with A-STR were older, predominantly women with more diastolic abnormalities and higher pulmonary pressures. All types of secondary TR were associated with all-cause mortality, highest in PH-TR and LV dysfunction-TR. CONCLUSIONS New-onset AFib vs. SR conferred a higher risk of the individual TR types related to sequelae of AFib and higher pacemaker implantation rates, although the distribution of TR types was similar. Secondary TR was universally associated with increased mortality.

Abstract
BACKGROUND Tricuspid regurgitation velocity (TRV), measured by echocardiography, is a surrogate marker for pulmonary hypertension. Limited pediatric studies have considered the association between TRV and surrogate markers of end-organ disease. METHODS We conducted a cross-sectional study that evaluated the prevalence of elevated TRV ≥2.5 m/s and its associations with renal and cerebrovascular outcomes in children with sickle cell disease (SCD) 1-21 years of age in two large sickle cell cohorts, the University of Alabama at Birmingham (UAB) sickle cell cohort, and the Sickle Cell Clinical Research and Intervention Program (SCCRIP) cohort at St. Jude Children's Research Hospital. We hypothesized that patients with SCD and elevated TRV would have higher odds of having either persistent albuminuria or cerebrovascular disease. RESULTS We identified 166 children from the UAB cohort (mean age: 13.49 ± 4.47 years) and 325 children from the SCCRIP cohort (mean age: 13.41 ± 3.99 years) with echocardiograms. The prevalence of an elevated TRV was 21% in both UAB and SCCRIP cohorts. Elevated TRV was significantly associated with cerebrovascular disease (odds ratio [OR] 1.88, 95% confidence interval [CI]: 1.12-3.15; p = .017) and persistent albuminuria (OR 1.81, 95% CI: 1.07-3.06; p = .028) after adjusting for age, sex, treatment, and site. CONCLUSION This cross-sectional, multicenter study identifies associations between surrogate markers of pulmonary hypertension with kidney disease and cerebrovascular disease. A prospective study should be performed to evaluate the longitudinal outcomes for patients with multiple surrogate markers of end-organ disease.

Abstract
INTRODUCTION Expanded hemodialysis (HDx) could provide clearance of larger middle-molecule uremic toxins. We compared the effect of hemodialysis with medium cut-off membranes and high-flux (HFHD) membranes regarding changes in inflammation and vascular and left ventricular function. METHODS This was a single-center, prospective, parallel-group comparative study. Patients were divided into two groups (HDx: 25 patients and HFHD: 26 patients). All measurements were performed at baseline and 12 weeks. Serum c-reactive protein, interkelukin-18, pentraxin-3, β-2 microglobulin, and brain natriuretic peptide were measured. We used pulse wave velocity and augmentation index to assess arterial stiffness and echocardiography to evaluate left and right ventricular function. FINDINGS We enrolled 51 patients. Although serum c-reactive protein, interkelukin-18, pentraxin 3, and β-2 microglobulin were significantly decreased in the HDx group (p = 0.02, p < 0.001, p = 0.002, and p = 0.02, respectively), there was no significant change in HFHD group at 12th week. Serum c-reactive protein and interkelukin-18were significantly lower in the HDx group compared to the HFHD group in the 12th week (p = 0.007 and p = 0.03, respectively). We observed a significant decrease in pulse wave velocity in the HDx group at the end of the study (p = 0.03). Although there was no significant change in pulse wave velocity in the HFHD group, pulse wave velocity was similar between the HDx and HFHD groups in the 12th week. We detected a significant decrease in the mean isovolumetric relaxation time in the HDx group (p = 0.006). However, there was no significant difference in isovolumetric relaxation time between the HDx and HFHD groups in the 12th week. DISCUSSION HDx provides better clearance of middle molecular uremic toxins and inflammatory biomarkers, and it may be associated with better central hemodynamic parameters and diastolic functions.

Abstract
PURPOSE OF REVIEW There has been increasing use of multimodality imaging in the evaluation of cardiomyopathies. RECENT FINDINGS Echocardiography, cardiac magnetic resonance (CMR), cardiac nuclear imaging, and cardiac computed tomography (CCT) play an important role in the diagnosis, risk stratification, and management of patients with cardiomyopathies. Echocardiography is essential in the initial assessment of suspected cardiomyopathy, but a multimodality approach can improve diagnostics and management. CMR allows for accurate measurement of volumes and function, and can easily detect unique pathologic structures. In addition, contrast imaging and parametric mapping enable the characterization of tissue features such as scar, edema, infiltration, and deposition. In non-ischemic cardiomyopathies, metabolic and molecular nuclear imaging is used to diagnose rare but life-threatening conditions such amyloidosis and sarcoidosis. There is an expanding use of CCT for planning electrophysiology procedures such as cardioversion, ablations, and device placement. Furthermore, CCT can evaluate for complications associated with advanced heart failure therapies such as cardiac transplant and mechanical support devices. Innovations in multimodality cardiac imaging should lead to increased volumes and better outcomes.

Abstract
INTRODUCTION Ischemic stroke is a leading cause of morbidity and mortality worldwide. Emerging evidence suggests that left atrial (LA) dysfunction could play a role in the pathophysiology of ischemic stroke, as a possible contributor and as a predictive biomarker. AREAS COVERED This narrative review details the intricate relationship between LA function, atrial fibrillation (AF), and ischemic stroke. We discuss imaging techniques used to assess LA function, the mechanisms by which impaired LA function may contribute to stroke, and its potential as a prognostic marker of stroke. EXPERT OPINION There is a lack of evidence-based treatments of LA dysfunction in both primary and secondary stroke prevention. This is partly due to the lack of a practical clinical definition and unanswered questions concerning the clinical implications of LA dysfunction in patients without AF. Until such questions are resolved, addressing well-known cardiovascular risk factors, like hypertension and obesity, should be prioritized for preventing AF and ischemic stroke. These risk factors are closely tied to atrial remodeling, emphasizing the importance of targeting primary modifiable factors for preventing future morbidity and mortality.

Abstract
BACKGROUND Tricuspid regurgitation (TR) adversely affects prognosis following mitral transcatheter edge-to-edge repair (TEER). We aimed to derive a risk stratification tool for patients undergoing TEER for mitral regurgitation while exhibiting significant TR. METHODS This is a single-center, retrospective analysis of 217 consecutive individuals referred to an isolated mitral TEER who had moderate-to-severe or greater TR at baseline. The primary outcome was the 1-year composite of all-cause mortality or heart failure hospitalizations. The cohort was randomly split in a 75%-to-25% ratio, creating train (n = 163) and test (n = 54) datasets. Model development, discrimination, and calibration were based on the train dataset. Internal validation was applied to the test dataset. RESULTS Overall, 81 (37.3%) patients experienced the primary outcome. After multivariable analysis, a score for predicting the primary outcome was constructed that utilized a 0-to-3 scale, in which each point represented one of three baseline variables independently associated with this combined endpoint: serum B-natriuretic peptide (BNP) level >1,000 pg/mL, qualitative right ventricular (RV) dysfunction on transthoracic echocardiogram, and cardiac implantable electronic device (CIED). C-statistic of the model was 0.66 (95% CI, 0.57-0.75, p = 0.002) and 0.75 (95% CI, 0.61-0.89, p = 0.004) in the train and test datasets, respectively-representing comparable performance to current, more complex tools. Neither this BNP-RV-CIED (BRC) score nor other models were prognostically meaningful in 32 patients excluded from the main analysis who underwent a combined mitral-tricuspid TEER. CONCLUSION The BRC score is a simple clinical prediction tool that may aid in the triage of isolated mitral TEER candidates with significant pre-existing TR.

Abstract
AIMS We aim to integrate the parameters of two-dimensional (2D) echocardiography and identify the high-risk population for all-cause mortality in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). METHODS The study involved a retrospective cohort population with STEMI who were admitted to Yongchuan Hospital of Chongqing Medical University between January 2016 and January 2019. Baseline data were collected, including 2D echocardiography parameters and left ventricular ejection fraction (LVEF). The parameters of 2D echocardiography were subjected to cluster analysis. Logistic regression models were employed to assess univariate and multivariate adjusted odds ratios (ORs) of cluster information in relation to all-cause mortality. Four logistic regression models were generated, utilizing cluster information, clinical variables, clinical variables in conjunction with LVEF, and clinical variables in conjunction with LVEF and cluster information as predictive variables, respectively. The area under the curve (AUC) were utilized to evaluate the incremental risk stratification value of cluster information. RESULTS The study included 633 participants with 28.8% female, a mean age of 65.68 ± 11.98 years. Over the course of a 3-year follow-up period, 108 (17.1%) patients experienced all-cause mortality. Utilizing cluster analysis of 2D echocardiography parameters, the patients were categorized into two distinct clusters, with statistically significant differences observed in most clinical variables, echocardiography, and survival outcomes between the clusters. Multivariate regression analysis revealed that cluster information was independently associated with the risk of all-cause mortality with adjusted OR 7.33 (95% confidence interval [CI] 3.99-14.06, P < 0.001). The inclusion of LVEF enhanced the predictive capacity of the model utilized with clinical variables with AUC 0.848 (95% CI 0.809-0.888) versus AUC 0.872 (95% CI 0.836-0.908) (P < 0.001), and the addition of cluster information further improved its predictive performance with AUC 0.906 (95% CI 0.878-0.934, P < 0.001). This cluster analysis was translated into a free available online calculator (https://app-for-mortality-prediction-cluster.streamlit.app/). CONCLUSIONS The 2D echocardiographic diagnostic information based on cluster analysis had good prognostic value for STEMI population, which was helpful for risk stratification and individualized intervention.

Abstract
BACKGROUND Growth differentiation factor-15 (GDF-15) has been shown to be associated with adverse clinical outcomes in patients after an acute coronary syndrome when measured soon after an event. Although dynamic in the acute phase after myocardial injury, GDF-15 has been shown to remain stable during convalescence. In this study, we aimed to assess the value of GDF-15 as a long-term prognostic marker for clinical outcomes when measured in the convalescent phase following an acute coronary syndrome. METHODS GDF-15 concentrations were measured in 1945 patients who were recruited between 2002 and 2009 to the Coronary Disease Cohort Study. For this analysis, follow-up was curtailed at 10 years and association of GDF-15 with all-cause death, cardiovascular death, recurrent myocardial infarction, and heart failure hospitalizations were assessed with multivariate Cox proportional hazard regression analysis. RESULTS After 10 years of follow-up, there were 648 deaths (348 from cardiovascular causes), 500 admissions for myocardial infarction, and 436 for heart failure. Four-month convalescent GDF-15 demonstrated a robust independent association with all endpoints, which remained after adjustment for Global Registry of Acute Coronary Events score and other convalescent biomarkers. When compared to the lowest quartile of GDF-15 concentrations, those in the highest quartile had a 3-fold increased risk of all-cause death. CONCLUSIONS Convalescent plasma GDF-15 is a strong and independent predictor of 10-year all-cause death, cardiovascular death, recurrent myocardial infarction, and heart failure admission following an acute coronary syndrome.

Abstract
BACKGROUND Moderate/severe aortic regurgitation (AR) with concomitant mitral regurgitation (MR) is a common multiple valve disease for which treatment strategies are controversial. The current study explored long-term outcomes of concomitant MR after AR surgery and the effect of combined mitral valvuloplasty. METHODS A total of 506 patients with moderate/severe AR and concomitant MR undergoing aortic valve surgery between January 2013 and December 2021 in our cardiac center were enrolled. Risk factors for early mortality, late mortality and persistent MR were identified by logistic regression and generalized linear mixed model. RESULTS At least one follow-up record was available for 96.3% patients up to May 2022 and 264 (66.8%) patients had no or trivial MR, 112 (28.4%) had mild MR, 16 (4.1%) had moderate MR and 3 (0.8%) patients had severe MR. Persistent MR was recorded for 92 (23.3%) patients during follow-up. Combined mitral valvuloplasty (odds ratio: 0.23; 95% confidential interval: 0.08-0.64; p = 0.005) and better left ventricular reverse remodeling (odds ratio: 0.99; 95% confidential interval: 0.986-0.996); p < 0.001) were found likely to reduce the possibility of persistent MR during follow-up. CONCLUSIONS Most patients with moderate/severe AR and concomitant MR had a good long-term post-surgical outcome for MR. However, a few had persistent MR during follow-up. Combined mitral valvuloplasty and better left ventricular reverse remodeling reduced the possibility of long-term persistent MR.

Abstract
PURPOSE For novice learners, converting two-dimensional (2D) images of echocardiography to three-dimensional (3D) cardiac structures is deemed challenging. This study aimed to develop an accurate dissection method of the heart to reproduce the transthoracic echocardiographic views on cadavers and elucidate new educational methods in human anatomy dissection courses. METHODS A total of 18 hearts were used in this study. After reflecting the anterior thoracic wall inferiorly, the hearts were excised from embalmed cadavers. Thereafter, three landmarks were set on the heart for each plane of the incision, and the hearts were incised to observe the three different echocardiographic views, which include the apical four-chamber view (A4C), parasternal long axis (PLAX) view, and parasternal short axis (PSAX) view at the papillary muscle level. If all structures for observation during routine echocardiography are clearly observed in each view, a successful incision is considered. All procedures and incisions were performed by the medical students. After a successful incision, hearts were returned to the original position in the pericardial sac for further observation. RESULTS The success rates of incision for each view were 83.3% (5/6 success cases), 83.3% (5/6 success cases), and 66.7% (4/6 success cases) in the A4C view, PLAX view, and PSAX view at the papillary muscle level, respectively. CONCLUSION This dissection method could probably be employed to reproduce transthoracic echocardiographic views on cadaveric hearts, which is beneficial for novice learners for a deeper understanding of the anatomy.

Abstract
BACKGROUND Preoperative systemic inflammation and nutritional status have been shown to affect prognosis in patients undergoing transcatheter aortic valve implantation (TAVI). In this study, we investigated the effect of the Naples Prognostic Score (NPS), which consists of four different parameters including these two components on short- and long-term prognosis in patients undergoing TAVI. METHODS In 343 patients (mean age 78.1 ± 8.4 years, 51.3% female) who underwent TAVI, the NPS score was calculated from the blood tests obtained before the procedure and the study population was divided into three according to the NPS value: those with 0 and 1 were divided into Group-1, those with 2 into Group-2, and those with 3 and 4 into Group-3. The relationship between NPS group and in-hospital adverse events and long-term survival was evaluated. RESULTS Systolic pulmonary artery pressure, STS score, presence of chronic lung disease and being in NPS Group-3 [adjusted odds ratio (adjOR): 3.93, 95% confidence interval (CI) (1.02-15.17), P = 0.047] were found to be independent predictors of in-hospital mortality. According to the multivariate Cox-regression model, both Group-2 NPS [adjusted hazard ratio (adjHR): 4.81, 95% CI (1.09-21.14), P = 0.037] and Group-3 NPS [adjHR: 10.1, 95% CI (2.31-43.36), P = 0.002] was an independent predictor of 2-year all-cause mortality after TAVI. There was no significant difference in perioperative adverse events between the groups except for postprocedural acute kidney injury. According to receiver-operating characteristic analysis, the optimal predictive value of NPS for in-hospital and long-term mortality was 2.5. CONCLUSION In patients who will be candidates for TAVI, NPS is a simple and effective tool for determining both short- and long-term prognosis.

Abstract
The data on myocardial perfusion of the percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) for obstructive hypertrophic cardiomyopathy (HOCM) are still lacking, although PIMSRA have been proved to be of great safety and efficacy. The aim of this study was to quantitatively analyze the changes in myocardial perfusion after PIMSRA using myocardial contrast echocardiography (MCE). 27 HOCM patients treated with PIMSRA were retrospectively analyzed, and their echocardiographic parameters and perfusion parameters of MCE were collected before and 12 months after PIMSRA. A reperfusion curve was used to quantify microvascular blood volume (A), microvascular flux rate (β), and microvascular blood flow (MBF) of each segment. Then the value difference (Δ) of parameters between post- and pre-operation were calculated. Finally, the correlation between the changes in MBF and in each echocardiographic parameter was analyzed. (1) Compared with baseline, the global A, β and MBF were significantly increased in HOCM patients after PIMSRA (all P < 0.001). The β, MBF were increased in the interventricular septum (P < 0.001, respectively), and the A, β, MBF were increased in the left ventricular wall (all P < 0.001). (2) Correlation analysis showed that the ΔMBF of interventricular septum was mainly negatively correlated with the maximum interventricular septum thickness (ΔIVSTmax, r=-0.670, P < 0.001), mean interventricular septum thickness (ΔIVSTmean, r=-0.690, P < 0.001), and left ventricular mass index (ΔLVMI, r=-0.774, P < 0.001), while the ΔMBF of left ventricular wall was positively correlated with left ventricular end-diastolic volume index (ΔLVEDVI, r = 0.621, P = 0.001) and stroke volume index (ΔSVI, r = 0.810, P < 0.001). Myocardial perfusion was improved at both interventricular septum and ventricular wall in HOCM patients after PIMSRA. MCE can provide a new dimension for the efficacy evaluation to PIMSRA procedure.

The Relative Apical Sparing Strain Pattern in Severe Aortic Valve Stenosis: A Marker of Adverse Cardiac Remodeling. J Pers Med 2024; 14:707.

Abstract
BACKGROUND The presence of a relative apical sparing (RAS) echocardiographic strain pattern raises a suspicion of underlying cardiac amyloidosis (CA). However, it is also increasingly observed in patients with aortic stenosis (AS). We aimed to evaluate the prevalence, dynamics, and clinical characteristics of the RAS strain pattern in severe AS patients who had been referred for surgical aortic valve replacement (SAVR). METHODS A total of 77 patients with severe AS and without CA were included with a mean age of 70 (62-73) years, 58% female, a mean aortic valve area index of 0.45 ± 0.1 cm2/m2, and a mean gradient of 54.9 (45-70) mmHg. RESULTS An RAS strain pattern was detected in 14 (18%) patients. RAS-positive patients had a significantly higher LV mass index (125 ± 28 g/m2 vs. 91 ± 32, p = 0.001), a lower LV ejection fraction (62 ± 12 vs. 68 ± 13, p = 0.040), and lower global longitudinal strain (-14.9 ± 3 vs. -18.7 ± 5%, p = 0.002). RAS strain pattern-positive patients also had higher B-type natriuretic peptide (409 (161-961) vs. 119 (66-245) pg/L, p = 0.032) and high-sensitivity troponin I (15 (13-29) vs. 9 (5-18) pg/L, p = 0.026) levels. Detection of an RAS strain pattern was strongly associated with increased LV mass index (OR 1.03, 95% CI 1.01-1.06, p < 0.001). The RAS strain pattern had resolved in all patients by 3 months after SAVR. CONCLUSIONS Our findings suggest that the RAS strain pattern can be present in patients with severe AS without evidence of CA. The presence of an RAS strain pattern is associated with adverse LV remodeling, and it resolves after SAVR.

Abstract
Objectives Predictive risk scores have a significant impact on patient selection and assessing the likelihood of complications following interventions in patients with severe aortic stenosis (AS). This study aims to explore the utility of machine learning (ML) techniques in predicting 30-day major adverse cardiac events (MACE) by analyzing parameters, including the Global Registry of Acute Coronary Events (GRACE) score. Methods This retrospective, multi-center, observational study enrolled 453 consecutive patients diagnosed with severe AS who underwent transcatheter aortic valve implantation (TAVI) from April 2020 to January 2023. The primary outcome was defined as a composition of MACE comprising periprocedural myocardial infarction (MI), cerebrovascular events (CVE), and all-cause mortality during the 1-month follow-up period after the procedure. Conventional binomial logistic regression and ML models were utilized and compared for prediction purposes. Results The study population had a mean age of 76.1, with 40.8% being male. The primary endpoint was observed in 7.5% of cases. Among the individual components of the primary endpoint, the rates of all-cause mortality, MI, and CVE were reported as 4.2%, 2.4%, and 1.9%, respectively. The ML-based Extreme Gradient Boosting (XGBoost) model with the GRACE score demonstrated superior discriminative performance in predicting the primary endpoint, compared to both the ML model without the GRACE score and the conventional regression model [Area Under the Curve (AUC)= 0.98 (0.91-0.99), AUC= 0,87 (0.80-0.98), AUC= 0.84 (0.79-0.96)]. Conclusion ML techniques hold the potential to enhance outcomes in clinical practice, especially when utilized alongside established clinical tools such as the GRACE score.

Abstract
OBJECTIVES We aimed to cardiologically evaluate the consequences of glycosaminoglycan (GAG) accumulation in the large vessels of patients with mucopolysaccharidosis (MPS). METHODS The left ventricular wall thickness, left ventricular mass (LVmass) were evaluated and aortic annulus diameter (AA), aortic sinus valsalva diameter (SV), sinotubular junction diameter (STJ), systolic aortic diameter (ADs), diastolic aortic diameter (ADd) body indices were obtained by dividing by the surface area. Aortic distensibility and stiffness index were obtained using aortic strain. Ejection fraction, mitral E and A velocities, mitral early diastolic tissue velocity (e'), E/A ratio, and E/e' ratio were evaluated. RESULTS The LVED-i, LVmass-i, AA-i, SV-i, STJ-i, ADs-i, and ADd-i values were significantly higher in the MPS group. While the E and e' velocities and E/A ratio were significantly low in the MPS group, the A velocity and E/e' ratio were significantly high. While the stiffness index, SBP, and PP values were significantly higher in the MPS group, the aortic strain and distensibility were significantly lower. There was a correlation between the stiffness index and the aortic strain, distensibility, SBP, PP, and ventricular function. Cardiac function, aortic diameter, and aortic elasticity characteristics were similar between patients with MPS who received ERT and those who did not. CONCLUSIONS In the MPS group, aortic elasticity properties were impaired, and aortic stiffness increased. ERT has positive effects on cardiac function, aortic diameter, and aortic stiffness in MPS patients. An increased LVmass-i and impaired ventricular geometric structure in patients with MPS may be associated with increased aortic stiffness.

Abstract
BACKGROUND European and U.S. clinical guidelines diverge regarding pulmonary hypertension (PHTN) in degenerative mitral regurgitation (DMR). Gaps in knowledge underpinning these divergences affect risk assessment and management recommendations attached to systolic pulmonary pressure (SPAP) in DMR. OBJECTIVES This study sought to define PHTN links to DMR severity, prognostic thresholds, and independent outcome impact in a large quantitative DMR registry. METHODS This study gathered a large multicentric registry of consecutive patients with isolated moderate-to-severe DMR, with DMR and SPAP quantified prospectively at diagnosis. RESULTS In 3,712 patients (67 ± 15 years, 36% women) with ≥ moderate-to-severe DMR, effective regurgitant orifice (ERO) was 0.42 ± 0.19 cm2, regurgitant volume 66 ± 327 mL/beat and SPAP 41 ± 16 mm Hg. Spline-curve analysis showed excess mortality under medical management emerging around SPAP 35 mm Hg and doubling around SPAP 50 mm Hg. Accordingly, severe pulmonary hypertension (sPHTN) (SPAP ≥50 mm Hg) was detected in 916 patients, moderate pulmonary hypertension (mPHTN) (SPAP 35-49 mm Hg) in 1,128, and no-PHTN (SPAP <35 mm Hg) in 1,668. Whereas SPAP was strongly associated with DMR-ERO, nevertheless excess mortality with sPHTN (adjusted HR: 1.65; 95% CI: 1.24-2.20) and mPHTN (adjusted HR: 1.44; 95% CI: 1.11-1.85; both P ≤ 0.005) was observed independently of ERO and all baseline characteristics and in all patient subsets. Nested models demonstrated incremental prognostic value of mPHTN and sPHTN (all P < 0.0001). Despite higher operative risk with mPHTN and sPHTN, DMR surgical correction was followed by higher survival in all PHTN ranges with strong survival benefit of early surgery (<3 months). Postoperatively, excess mortality was abolished (P ≥ 0.30) in mPHTN, but only abated in sPHTN. CONCLUSIONS This large international registry, with prospectively quantified DMR and SPAP, demonstrates a Doppler-defined PHTN impact on mortality, independent of DMR severity. Crucially, it defines objectively the new and frequent mPHTN range, independently linked to excess mortality under medical management, which is abolished by DMR correction. Thus, at DMR diagnosis, Doppler-SPAP measurement defining these new PHTN ranges, is crucial to guiding DMR management.

Echocardiography-Derived Forward Left Ventricular Output Improves Risk Prediction in Systolic Heart Failure. J Am Soc Echocardiogr 2024:S0894-7317(24)00321-3.

Abstract
BACKGROUND Although it is widely used to classify patients with heart failure (HF), the prognostic role of left ventricular ejection fraction (LVEF) is debated. The aim of this study was to test the hypothesis that echocardiographic measures of forward left ventricular (LV) output, being more representative of cardiac hemodynamics, might improve risk prediction in a large cohort of patients with HF with systolic dysfunction. METHODS Consecutive stable patients with HF with LVEF <50% on guideline-recommended therapies undergoing echocardiography including the evaluation of forward LV output (i.e., LV outflow tract [LVOT] velocity-time integral [VTI], stroke volume index [SVi], and cardiac index) over a 6-year period were selected and followed for the end point of cardiac and all-cause death. RESULTS Among the 1,509 patients analyzed (mean age, 71 ± 12 years; 75% men; mean LVEF, 35 ± 9%), 328 (22%) died during a median follow-up period of 28 months (interquartile range, 14-40 months), 165 (11%) of cardiac causes. On multivariable regression analysis, LVOT VTI (P < .001), SVi (P < .001), and cardiac index (P < .001), but not LVEF (P > .05), predicted cardiac and all-cause death. The optimal prognostic cutoffs for LVOT VTI, SVi, and cardiac index were 15 cm, 38 mL/m2, and 2 L/min/m2, respectively. Adding each of these measures to a multivariable risk model (including clinical, biohumoral, and echocardiographic markers) improved risk prediction (P < .001). Among the different measures of forward LV output, cardiac index was less accurate than LVOT VTI and SVi. CONCLUSIONS The echocardiographic evaluation of forward LV output improves risk prediction in patients with HF across a wide LVEF spectrum over other well-established clinical, biohumoral, and echocardiographic prognostic markers.

Abstract
BACKGROUND The left atrium approach for atrial fibrillation (AF) ablation requires an atrial transseptal puncture that may cause an iatrogenic atrial septal defect (iASD). This study aimed to investigate the incidence and predictors of iASD in catheter ablation, assessed by transthoracic echocardiography (TTE), a relatively non-invasive technique frequently employed in follow-up. METHODS This retrospective study included 639 patients (489 male; 60.2±10.7years) who underwent initial catheter ablation for AF between May 2005 and June 2018. All patients underwent preprocedural transesophageal echocardiography (pre-TEE), preprocedural TTE (pre-TTE), and TTE one day after the procedure (post-TTE). iASD incidence after 6months (6M), preprocedural characteristics, and procedure methods were evaluated. RESULTS Patent foramen ovale (PFO) was diagnosed in 42 patients (6.6%) using pre-TEE and in 11 patients using pre-TTE (26.2% of the patients with PFO in pre-TEE). Among the 597 patients without PFO, 497 underwent 6M-TTE. iASD was observed in 59.6% of patients using post-TTE and 4.6% using 6M-TTE. In the univariate logistic regression analysis, the total diameter of the sheath through the septum (odds ratio 1.15, p<0.001) or two sheaths through a single puncture (odds ratio 4.17, p=0.001) were independent risk factors on iASD incidence in 6M-TTE. iASD was also more likely to occur via cryoballoon ablation using a larger sheath than radiofrequency catheter ablation. CONCLUSIONS iASD was not a rare complication. A larger sheath diameter or two sheaths through a single puncture were associated with the incidence of iASD.

[PMID: 39063927 PMCID: PMC11278238 DOI: 10.3390/jpm14070673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 06/18/2024] [Accepted: 06/20/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND Femoral fractures often lead to complications such as altered pulmonary hemodynamics. Right ventricular global longitudinal strain (RV GLS), which correlates with pulmonary hemodynamics, indicates the subclinical function of the right ventricle (RV). This study aimed to investigate the predictive value of RV GLS for the risk of adverse clinical composite outcomes in patients with femoral fractures. METHODS Data were obtained from a prospective single-center cohort of patients hospitalized for femoral fractures and followed up for at least 1 year between March 2021 and October 2022. The primary outcome was the development of an adverse composite clinical event, which included pneumonia, pulmonary oedema or effusion, pulmonary thromboembolism, and all-cause mortality within the 1-year period following surgery. RESULTS Among the 163 patients, 36 (22.09%) experienced adverse composite clinical events during 1-year follow-up. The adverse outcome group demonstrated poorer RV GLS and RV free wall strain values than the non-adverse outcome group. The optimal cut-off value of RV GLS for predicting composite adverse clinical events was -12.55%. The cumulative composite event-free survival rate was significantly lower in the RV GLS ≥ -12.55% group (log-rank p-value = 0.003). After adjusting for confounding factors, multivariate Cox proportional hazards regression analyses showed that RV GLS ≥ -12.55% independently increased the risk of composite adverse clinical events by 2.65-fold. CONCLUSIONS Poor RV GLS is a significant predictor of adverse clinical outcomes in patients with femoral fractures. Specifically, an RV GLS value of ≥ -12.55% indicated a substantially increased risk of adverse events.

Abstract
INTRODUCTION This study aims to examine the relationship between fluid overload, Vascular Endothelial Growth Factor C (VEGF-C), plasma Angiotensinogen (pAGT), and echocardiography findings in hemodialysis patients. METHODS This was a single-center, cross-sectional study. Patients were divided into two groups according to mid-week inter-dialytic weight gain (mIDWG): (1) mIDWG ≤3% and (2) mIDW >3%. RESULTS A total of 55 patients were enrolled in this study. While the mean pAGT and left ventricular mass index were significantly higher in patients with mIDWG >3% compared to patients with mIDWG ≤3%, VEGF-C was similar between groups. pAGT ≥76.8 mcg/L, VEGF-C ≤175.5 pg/ML, and pAGT /VEGF-C ≥0.45 were significant cut-offs for the prediction of left ventricular hypertrophy(LVH). Univariate logistic regression analysis revealed that these cut-off values were significantly associated with LVH. CONCLUSION Renin-angiotensin-aldosterone system activation may persist in hemodialysis patients with excessive IDWG. Additionally, pAGT and VEGF-C could be risk factors for the development of LVH.

Abstract
Echocardiography is pivotal for diagnosis and monitoring of hypertrophic cardiomyopathy (HCM) and can evaluate myocardial function using myocardial work (MW) calculations. Echocardiography is often supplemented by cardiovascular magnetic resonance (CMR) imaging, which can detect myocardial fibrosis using late gadolinium enhancement (LGE). We sought to study the relationship between baseline LGE and MW at baseline and during follow-up in pediatric HCM patients. During the study period (2008-2023), 75 patients were followed up for HCM. In 14 patients (age 14.2 ± 2.8 years, 50.0% male, 6.4 ± 2.9 years follow-up), both LGE-CMR and echocardiography were performed. Global work index (GWI), global constructive work (GCW), global wasted work, and global work efficiency (GWE) were measured, and myocardial fibrosis was estimated by qualitative assessment of LGE. Patients with LGE (n = 7) exhibited significantly impaired baseline MW, including GWI (mean difference, MD - 487.4 mmHg %, 95% CI [- 866.8 mmHg % to - 108.3 mmHg %], p = 0.027), GCW (MD - 536.8 mmHg %, 95% CI [- 929.8 mmHg % to - 144.4 mmHg %], p = 0.020), and GWE (MD - 4.4%, 95% CI [- 8.1% to - 0.7%], p = 0.039). Regional analysis revealed impaired MW indices in segments with LGE, notably basal and mid septal segments. GWI demonstrated high diagnostic performance for LGE presence (sensitivity 93%, specificity 88%, and area under receiver operating characteristic curve 0.85). Baseline LGE presence had no significant impact on MW deterioration during follow-up. MW is significantly impaired in HCM patients with myocardial fibrosis, highlighting potential utility of echocardiography-derived MW analysis as a valuable tool.

Abstract
Background Residual mitral regurgitation (MR) is frequent after transcatheter edge-to-edge repair (TEER). There is controversy regarding the clinical impact of residual MR and its quantitative assessment by transthoracic echocardiography (TTE), which is often challenging with multiple eccentric jets and artifact from the clip. The utility of the velocity time integral (VTI) ratio between the mitral valve (MV) and left ventricular outflow tract (LVOT), (VTIMV/LVOT), a simple Doppler measurement that increases with MR, has not been assessed post TEER. Methods Baseline characteristics, clinical outcomes, and TTE data from patients who underwent TEER between 2014 and 2021 across three academic centers were retrospectively analyzed. Post-procedure TTEs were evaluated for VTIMV/LVOT in the first three months after TEER. One-year outcomes including all-cause and cardiac mortality, major adverse cardiac events, and MV reintervention were compared between patients with high VTIMV/LVOT (≥2.5) and low (<2.5). Results In total, 372 patients were included (mean age 78.7 ± 8.8 years, 68 % male, mean pre-TEER ejection fraction of 50.5 ± 14.7 %). Follow up TTEs were performed at a median of 37.5 (IQR 30-48) days post-procedure. Patients with high VTIMV/LVOT had significantly higher all-cause mortality (HR 2.10, p = 0.003), cardiac mortality (HR 3.03, p = 0.004) and heart failure admissions (HR 2.28, p < 0.001) at one-year post-procedure. There was no association between raised VTIMV/LVOT and subsequent MV reintervention. Conclusion High VTIMV/LVOT has clinically significant prognostic value at one year post TEER. This tool could be used to select patients for consideration of repeat intervention.

Impairment in Right Ventricular-Pulmonary Arterial Coupling in Overweight and Obesity. J Clin Med 2024; 13:3389. [PMID: 38929919 PMCID: PMC11203835 DOI: 10.3390/jcm13123389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 05/28/2024] [Accepted: 06/06/2024] [Indexed: 06/28/2024] Open
Abstract
Background: The association of obesity with right ventricular function and the interplay between right heart and pulmonary circulation is incompletely understood. We evaluate the role of obesity as a determinant of right ventricular-pulmonary artery coupling (RVAC). Methods: We retrospectively studied consecutive subjects without overt cardiovascular or pulmonary disease. Subjects were stratified according to body mass index (BMI) as normal weight, overweight, or obese. A transthoracic echocardiographic study was used to assess left and right heart functional and structural parameters. RVAC was assessed using the ratio of peak systolic velocity of the tricuspid annulus to pulmonary artery systolic pressure (PASP). Results: A total of 145 subjects were enrolled with diabetes mellitus incidence higher in obese. There was no difference in left ventricular global longitudinal strain and in PASP or markers of right ventricular systolic function based on BMI. RVAC was significantly lower in the presence of obesity (normal weight: 0.52 (0.19) cm·(sec·mmHg)-1 vs. overweight: 0.47 (0.16) cm·(sec·mmHg)-1 vs. obese: 0.43 (0.14) cm·(sec·mmHg)-1, p = 0.03), even after adjustment for confounders (β: -0.085, 95% confidence interval: -0.163, -0.009, p = 0.029). Conclusions: Our findings highlight the relationship between metabolic impairment and RVAC, suggesting additional mechanisms for heart failure development observed in obese subjects.

A machine learning-derived risk score to predict left ventricular diastolic dysfunction from clinical cardiovascular magnetic resonance imaging. Front Cardiovasc Med 2024; 11:1382418. [PMID: 38903970 PMCID: PMC11187483 DOI: 10.3389/fcvm.2024.1382418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 05/27/2024] [Indexed: 06/22/2024] Open
Abstract
Introduction The evaluation of left ventricular diastolic dysfunction (LVDD) by clinical cardiac magnetic resonance (CMR) remains a challenge. We aimed to train and evaluate a machine-learning (ML) algorithm for the assessment of LVDD by clinical CMR variables and to investigate its prognostic value for predicting hospitalized heart failure and all-cause mortality. Methods LVDD was characterized by echocardiography following the ASE guidelines. Eight demographic and nineteen common clinical CMR variables including delayed enhancement were used to train Random Forest models with a Bayesian optimizer. The model was evaluated using bootstrap and five-fold cross-validation. Area under the ROC curve (AUC) was utilized to evaluate the model performance. An ML risk score was used to stratify the risk of heart failure hospitalization and all-cause mortality. Results A total of 606 consecutive patients underwent CMR and echocardiography within 7 days for cardiovascular disease evaluation. LVDD was present in 303 subjects by echocardiography. The performance of the ML algorithm was good using the CMR variables alone with an AUC of 0.868 (95% CI: 0.811-0.917), which was improved by combining with demographic data yielding an AUC 0.895 (95% CI: 0.845-0.939). The algorithm performed well in an independent validation cohort with AUC 0.810 (0.731-0.874). Subjects with higher ML scores (>0.4121) were associated with increased adjusted hazard ratio for a composite outcome than subjects with lower ML scores (1.72, 95% confidence interval 1.09-2.71). Discussion An ML algorithm using variables derived from clinical CMR is effective in identifying patients with LVDD and providing prognostication for adverse clinical outcomes.

Myocardial Work Indices Predict Hospitalization in Patients with Advanced Heart Failure. Diagnostics (Basel) 2024; 14:1196.

Abstract
BACKGROUND An increasing proportion of heart failure (HF) patients progress to the advanced stage (AdHF) with high event rates and limited treatment options. Echocardiography, particularly Speckle Tracking-derived myocardial work (MW), is useful for HF diagnosis and prognosis. We aimed to assess MW's feasibility in the prognostic stratification of AdHF. METHODS We retrospectively screened patients with AdHF who accessed our hospital in 2018-2022. We excluded subjects with inadequate acoustic windows; unavailable brachial artery cuff pressure at the time of the echocardiography; atrial fibrillation; and mitral or aortic regurgitation. We measured standard parameters and left ventricular (LV) strain (LS) and MW. The population was followed up to determine the composite outcomes of all-cause mortality, left ventricular assist device implantation and heart transplantation (primary endpoint), as well as unplanned HF hospitalization (secondary endpoint). RESULTS We enrolled 138 patients, prevalently males (79.7%), with a median age of 58 years (IQR 50-62). AdHF etiology was predominantly non-ischemic (65.9%). Thirty-five patients developed a composite event during a median follow-up of 636 days (IQR 323-868). Diastolic function, pulmonary pressures, and LV GLS and LV MW indices were not associated with major events. Contrarily, for the secondary endpoint, the hazard ratio for each increase in global work index (GWI) by 50 mmHg% was 0.90 (p = 0.025) and for each increase in global constructive work (GCW) by 50 mmHg% was 0.90 (p = 0.022). Kaplan-Meier demonstrated better endpoint-free survival, with an LV GWI ≥ 369 mmHg%. CONCLUSIONS GWI and GCW, with good feasibility, can help in the better characterization of patients with AdHF at higher risk of HF hospitalization and adverse events, identifying the need for closer follow-up or additional HF therapy.
