Kaohsiung J Med Sci 2024; 40:384-394. [PMID: 38332510 DOI: 10.1002/kjm2.12808] [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: 07/29/2023] [Revised: 12/15/2023] [Accepted: 01/08/2024] [Indexed: 02/10/2024] Open
Abstract
Transcatheter aortic valve replacement (TAVR) is a well-established procedure using a catheter-introduced valve prosthesis for patients with severe aortic stenosis (AS). This retrospective study investigated sex-related differences in pre- and post-TAVR clinical and hemodynamic outcomes and analyzed data of the first 100 cases at Kaohsiung Medical University Chung-Ho Memorial Hospital (KMUH) between December 2013 and December 2021. Baseline characteristics, procedural outcomes, mortality rates, and echocardiographic parameters were analyzed and compared between sexes. Among the 100 patients, male (46%) and female (54%) were of similar age (mean age, male 86.0 years vs. female 84.5 years) and of the same severity of AS (mean pressure gradient, male 47.5 mmHg vs. female 45.7 mmHg) at the time receiving the TAVR procedure. Women had smaller aortic valve areas calculated by continuity equation (0.8 ± 0.3 cm2 vs. 0.7 ± 0.2 cm2, p < 0.001). In addition, women had better left ventricle ejection fraction (59.6 ± 14.0% vs. men 54.7 ± 17.2%, p < 0.01). In the post-TAVR follow-up, regression of left ventricle mass and dimension was better in women than in men. None of the patient died within 30 days after the procedure, and women tended to have a more favorable survival than men (2-year mortality and overall mortality rate in 8.3 year, women 9.1% and 22.2% vs. men 22.2% and 34.8%; p = 0.6385 and 0.1277, respectively). In conclusion, the sex-based difference in post-TAVR regression of LV remodeling suggests a need for sex-based evaluation for patients with severe AS and their post TAVR follow-up.

Abstract
Transcatheter aortic valve replacement (TAVR) has emerged as a ground-breaking, minimally invasive alternative to traditional open-heart surgery, primarily designed for elderly patients initially considered unsuitable for surgical intervention due to severe aortic stenosis. As a result of successful large-scale trials, TAVR is now being routinely applied to a broader spectrum of patients. In deciding between TAVR and surgical aortic valve replacement, clinicians evaluate various factors, including patient suitability and anatomy through preprocedural imaging, which guides prosthetic valve sizing and access site selection. Patient surgical risk is a pivotal consideration, with a multidisciplinary team making the ultimate decision in the patient's best interest. Periprocedural imaging aids real-time visualization but is influenced by anaesthesia choices. A comprehensive postprocedural assessment is critical due to potential TAVR-related complications. Numerous trials have demonstrated that TAVR matches or surpasses surgery for patients with diverse surgical risk profiles, ranging from extreme to low risk. However, long-term follow-up data, particularly in low-risk cases, remains limited, and the applicability of published results to younger patients is uncertain. This review delves into key TAVR studies, pinpointing areas for potential improvement while delving into the future of this innovative procedure. Furthermore, it explores the expanding role of TAVR technology in addressing other heart valve replacement procedures.

Abstract
Background There are few reports on the postoperative left ventricular mass (LVM), aortic valve area (AVA), and pressure gradient (PG) after surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) in Japan. We aimed to compare the postoperative LVM, AVA, stroke volume (SV), PG, and long-term outcomes between patients undergoing SAVR and TAVR procedures from single center in Japan. Methods This was a retrospective cohort study. We included 107 patients who underwent simple SAVR between January 2012 and May 2022 (SAVR group, n=107) and 274 who underwent TAVR between January 2016 and May 2022 (TAVR group, n=274). The overall mean follow-up periods was 28.8±25.9 months (median: 24 months; range, 0.03-117 months). Results The aortic valve mean PG (mmHg) was significantly smaller in the TAVR group than in the SAVR group (P<0.001). The AVA index (cm2/m2) was significantly larger in the TAVR group than in the SAVR group (P<0.001). The SV index (mL/m2) was significantly smaller in the SAVR group than in the TAVR group (P=0.02). The LVM index (LVMI) (g/m2) was significantly smaller in the SAVR group than in the TAVR group (P<0.001). The incidence of mild or higher postoperative paravalvular leak (PVL) and pacemaker implantation were significantly higher in the TAVR group. The 5-year postoperative mortality, re-hospitalization, and major adverse cerebral and cardiovascular events (MACCEs) were significantly better in the SAVR group. Conclusions The postoperative aortic valve PG, AVA, and SV were better in the TAVR group; however, LVM regression and postoperative outcomes were better in the SAVR group.

Abstract
BACKGROUND We aim to determine predictors of inadequate left ventricular mass index (LVMi) regression at mid-term after transcatheter aortic valve replacement (TAVR), including the potential role of epicardial adipose tissue (EAT). METHODS We retrospectively reviewed patients with both echocardiographic assessments and multi-slice computed tomography (MSCT) obtained one year after TAVR. The change of LVMi, the volume and the average CT attenuation of EAT from baseline to one-year follow-up was calculated. Patients were divided into two groups by the percentage change of LVMi at a cut-off of 15%. RESULTS A total of 152 patients were included with a median age of 74 years (interquartile range [IQR] 69-78 years) and 56.6% being male. LVMi decreased (P < 0.0001) while EAT volume increased and the average CT attenuation decreased (both P < 0.0001) at one year. Baseline atrial fibrillation (P = 0.042), mitral regurgitation ≥ mild (P = 0.006), aortic regurgitation (AR) > mild (P = 0.001) and the change in the average CT attenuation of EAT (P = 0.026) were different between the decrease of LVMi ≥ 15% and < 15%. AR > mild at baseline was the only statistically significant predictor of a decrease of LVMi < 15% at one year (OR 0.33, 95% CI: 0.13 to 0.84, P = 0.021) in multivariate regression. CONCLUSIONS Concomitant more-than-mild AR might predict better left ventricular reverse remodeling regression after TAVR.

Abstract
Left ventricular hypertrophy is a leading risk factor for cardiovascular morbidity and mortality. Although reverse ventricular remodelling was long thought to be irreversible, evidence from the past three decades indicates that this process is possible with many existing heart disease therapies. The regression of pathological hypertrophy is associated with improved cardiac function, quality of life and long-term health outcomes. However, less than 50% of patients respond favourably to most therapies, and the reversibility of remodelling is influenced by many factors, including age, sex, BMI and disease aetiology. Cardiac hypertrophy also occurs in physiological settings, including pregnancy and exercise, although in these cases, hypertrophy is associated with normal or improved ventricular function and is completely reversible postpartum or with cessation of training. Studies over the past decade have identified the molecular features of hypertrophy regression in health and disease settings, which include modulation of protein synthesis, microRNAs, metabolism and protein degradation pathways. In this Review, we summarize the evidence for hypertrophy regression in patients with current first-line pharmacological and surgical interventions. We further discuss the molecular features of reverse remodelling identified in cell and animal models, highlighting remaining knowledge gaps and the essential questions for future investigation towards the goal of designing specific therapies to promote regression of pathological hypertrophy.

Abstract
Transcatheter aortic valve implantation (TAVI) is an increasingly popular treatment option for patients with severe aortic stenosis. Recent advancements in technology and imaging tools have significantly contributed to the success of TAVI procedures. Echocardiography plays a pivotal role in the evaluation of TAVI patients, both before and after the procedure. This review aims to provide an overview of the most recent technical advancements in echocardiography and their use in the follow-up of TAVI patients. In particular, the focus will be on the examination of the influence of TAVI on left and right ventricular function, which is frequently accompanied by other structural and functional alterations. Echocardiography has proven to be key also in detecting valve deterioration during extended follow-up. This review will provide valuable insights into the technical advancements in echocardiography and their role in the follow-up of TAVI patients.

Abstract
INTRODUCTION In aortic stenosis (AS), the heart transitions from adaptive compensation to an AS cardiomyopathy and eventually leads to decompensation with heart failure. Better understanding of the underpinning pathophysiological mechanisms is required in order to inform strategies to prevent decompensation. AREAS COVERED In this review, we therefore aim to appraise the current pathophysiological understanding of adaptive and maladaptive processes in AS, appraise potential avenues of adjunctive therapy before or after AVR and highlight areas of further research in the management of heart failure post AVR. EXPERT OPINION Tailored strategies for the timing of intervention accounting for individual patient's response to the afterload insult are underway, and promise to guide better management in the future. Further clinical trials of adjunctive pharmacological and device therapy to either cardioprotect prior to intervention or promote reverse remodeling and recovery after intervention are needed to mitigate the risk of heart failure and excess mortality.

Abstract
AIMS This study aimed to clarify the relationship between cardiovascular prognosis and left ventricular hypertrophy (LVH) in patients with severe aortic stenosis who underwent transcatheter aortic valve replacement (TAVR) and to investigate the relationship between cardiac sympathetic nerve (CSN) function and these factors using 123 I-metaiodobenzylguanidine scintigraphy. METHODS AND RESULTS In this single-centre, retrospective observational study, 349 patients who underwent TAVR at our institution between July 2017 and May 2020 were divided into two groups: those with severe LVH pre-operatively [severe LVH (+) group] and those without LVH pre-operatively [severe LVH (-) group]. The rates of freedom from cardiovascular events (cardiovascular death and heart failure hospitalization) were compared. The relationship between changes in left ventricular mass index (LVMi) and changes in delay heart-mediastinum ratio (H/M) from before TAVR to 6 months after TAVR was also investigated. The event-free rate was significantly lower in the severe LVH (+) group (87.1% vs. 96.0%, log-rank P = 0.021). The severe LVH (+) group exhibited a significantly lower delay H/M value, scored by 123 I-metaiodobenzylguanidine scintigraphy, than the severe LVH (-) group (2.33 [1.92-2.67] vs. 2.67 [2.17-3.68], respectively, P < 0.001). Moreover, the event-free rate of post-operative cardiovascular events was lower among patients with a delay H/M value < 2.50 than that among other patients (87.7% vs. 97.2%, log-rank P = 0.012). LVMi was significantly higher (115 [99-130] vs. 90 [78-111] g/m2 , P < 0.001) and delay H/M value was significantly lower (2.53 [1.98-2.83] vs. 2.71 [2.25-3.19], P = 0.025) in the severe LVH (+) group than in the severe LVH (-) group at 6 months after TAVR. Patients with improved LVH at 6 months after TAVR also had increased delay H/M (from 2.51 [2.01-2.81] to 2.67 [2.26-3.02], P < 0.001), whereas those without improved LVH had no significant change in delay H/M (from 2.64 [2.23-3.06] to 2.53 [1.97-3.00], P = 0.829). CONCLUSIONS Severe LVH before TAVR is a prognostic factor for poor post-operative cardiovascular outcomes. LVH associated with aortic stenosis and CSN function are correlated, suggesting their involvement in LVH prognosis.

Abstract
The impact of left ventricle (LV) hypertrophy (LVH) regression on contractility-associated measures, the extent of residual cardiac dysfunction and prognostic implications after the initial remodeling process after transcatheter aortic valve replacement (TAVR) has not been investigated. We aimed to assess whether greater LV mass regression from pre-TAVR to 12-months after TAVR was associated with increased systolic function; and assess the prognostic value of residual LVH, systolic function and contractility-associated measures 12-months after TAVR. A total of 439 symptomatic patients were included and examined by echocardiography. LVH regression was assessed as percentage change in LV mass index (LVMi) from baseline to 12-months after TAVR. Midwall fractional shortening (mFS) and stress-corrected (SC-mFS) were used as contractility-associated measures. Primary outcome was all-cause mortality. SC-mFS increased from 0.94 (0.7) at baseline (BS) to 1.22 (0.7) (p < 0.05) 12-months after TAVR for patients with the most LVH regression, compared to patients with no LV regression (BS 1.06 (0.7) to 1.04 (0.5), NS). At 12-months after TAVR, multivariate analysis showed independent prognostic value of LVEF < 50% or GLS < 15% (HR 1.59, p = 0.049) and mFS < 14% (HR 1.99, p = 0.002) for future all cause death. LVH regression in AS after TAVR is associated with significant improvements of LV systolic function in contrast to patients without LV regression. Residual LVH and subsequent LV systolic dysfunction is substantial 12 months after TAVR and are associated with reduced survival. Impaired mFS and the combination of abnormal LVEF or GLS independently predicted all-cause mortality beyond 12 months after TAVR.

Chen JS, Huang JH, Chiu KM, Chiang CY. Extent of Left Ventricular Mass Regression and Impact of Global Left Ventricular Afterload on Cardiac Events and Mortality after Aortic Valve Replacement. J Clin Med 2022; 11:jcm11247482. [PMID: 36556098 PMCID: PMC9783780 DOI: 10.3390/jcm11247482] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/09/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022] Open
Abstract
Patient-prosthesis mismatch (PPM) causes a high transvalvular pressure gradient and residual left ventricular (LV) hypertrophy, consequently influencing long-term results. This study aimed to find the relationships between hemodynamic parameters and LV mass regression and determine the risk predictors of major adverse cardiovascular and cerebral events (MACCE) after aortic valve replacement (AVR) for aortic stenosis. Methods and Results: Preoperative and postoperative Doppler echocardiography data were evaluated for 120 patients after AVR. The patients' mean age was 67.7 years; 55% of the patients were male. Forty-four (37%) patients suffered from MACCE during a mean follow-up period of 3.6 ± 2 years. The following hemodynamic parameters at follow-up were associated with lower relative indexed LV mass (LVMI) regression: lower postoperative indexed effective orifice area, greater mean transvalvular pressure gradient (MPG), greater stroke work loss (SWL), and concentric or eccentric LV remodeling mode. The following hemodynamic parameters at follow-up were associated with a higher risk of MACCE: higher valvuloarterial impedance (ZVA), greater SWL, greater MPG, greater relative wall thickness, greater LVMI, and hypertrophic LV remodeling mode. Lower relative LVMI regression was associated with a higher risk of MACCE (hazard ratio, 1.01: 95% confidence interval, 1.003-1.03). The corresponding cutoff of relative LVMI regression was -14%. Conclusions: Changes in hemodynamic parameters were independently associated with relative LVMI regression. Impaired reverse remodeling and persistent residual LV hypertrophy were independent risk predictors of MACCE. An LVMI regression lower than 14% indicated higher MACCE. A postoperative ZVA greater than 3.5 mmHg/mL/m2 was an independent risk predictor of cardiac events and mortality after AVR. Preventive strategies should be used at the time of the operation to avoid PPM.

The cardiac computed tomography-derived extracellular volume fraction predicts patient outcomes and left ventricular mass reductions after transcatheter aortic valve implantation for aortic stenosis. J Cardiol 2022; 81:476-484. [PMID: 36503064 DOI: 10.1016/j.jjcc.2022.12.002] [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: 07/21/2022] [Revised: 11/23/2022] [Accepted: 11/25/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Transcatheter aortic valve implantation (TAVI) improved outcome of patients with severe aortic valve stenosis (AS). Myocardial fibrosis is associated with AS-related pathological left ventricular (LV) remodeling and predicts cardiovascular mortality after TAVI. The present study aimed to investigate the impact of preoperative extracellular volume (ECV) assessed by computed tomography (CT) on left ventricular mass (LVM) regression and clinical outcomes in severe AS patients after TAVI. METHODS We examined 71 consecutive severe AS patients who underwent CT with ECV determination before TAVI. ECV was calculated as the ratio of the change in Hounsfield units in the myocardium and LV blood before and after contrast administration, multiplied by (1-hematocrit). Delayed scan was performed at 5 min after contrast injection. Echocardiography was performed before and 6 months after TAVI. The primary endpoint was heart failure (HF) hospitalization after TAVI. Patients were divided into two subgroups according to the median value of global ECV with 32 % (Low-ECV group: n = 35, and High-ECV group: n = 36). RESULTS No significant differences were observed in background characteristics between the 2 groups. However, the preoperative LV ejection fraction and LVM index were similar between the 2 groups, the Low-ECV group had greater LVM index reduction than the High-CV group after 6 months (p < 0.001). Kaplan-Meier curves demonstrated that the High-ECV group had significantly higher rate of HF hospitalization than the Low-ECV group (p = 0.016). In addition, multivariate analyses identified high global ECV as an independent predictor of HF hospitalization (HR 10.8, 95 % confidence interval 1.36 to 84.8, p = 0.024). CONCLUSION The low preoperative ECV assessed by CT is associated with the greater LVM regression, and predict better outcome in AS patients after TAVI.

Abstract
BACKGROUND The impact of aortic valve replacement (AVR) on progression/regression of extra-valvular cardiac damage and its association with subsequent prognosis is unknown. OBJECTIVES To describe evolution of cardiac damage post-AVR and its association with outcomes. METHODS Patients undergoing transcatheter or surgical AVR from the PARTNER 2 and 3 trials were pooled and classified by cardiac damage stage at baseline and 1-year (Stage 0, no damage; Stage 1, left ventricular damage; Stage 2, left atrial or mitral valve damage; Stage 3, pulmonary vasculature or tricuspid valve damage; Stage 4, right ventricular damage). Proportional hazards models determined association between change in cardiac damage post-AVR and 2-year outcomes. RESULTS Among 1974 patients, 121 (6.1%) were Stage 0, 287 (14.5%) Stage 1, 1014 (51.4%) Stage 2, 412 (20.9%) Stage 3, and 140 (7.1%) Stage 4 pre-AVR. Two-year mortality was associated with extent of cardiac damage at baseline and 1-year. Compared with baseline, cardiac damage improved in ∼15%, remained unchanged in ∼60%, and worsened in ∼25% of patients at 1-year. One-year change in cardiac damage stage was independently associated with mortality (adjHR for improvement=0.49; no change=1.0; worsening=1.95; p=0.023) and composite of death or heart failure hospitalization (adjHR for improvement=0.60; no change=1.0; worsening=2.25; p<0.001) at 2 years. CONCLUSION In patients undergoing AVR, extent of extravalvular cardiac damage at baseline and its change at 1-year have important prognostic implications. These findings suggest that earlier detection of AS and intervention prior to development of irreversible cardiac damage may improve global cardiac function and prognosis.

Abstract
Aims There are limited data about the intraprocedural haemodynamic study performed immediately before and after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis (AS). We aimed to evaluate the acute haemodynamic impact of TAVI in patients with severe AS and to investigate invasive and non‐invasive parameters predicting all‐cause mortality. Methods and results A total of 245 consecutive AS patients (43% male, mean age 80.3 ± 7.3 years) undergoing TAVI were enrolled. Intraprocedural left heart catheterization (LHC) and echocardiogram before and after TAVI were performed. The clinical endpoint was the death for any cause. LHC after TAVI revealed significant changes in aortic and left ventricular (LV) pressures, including indexes of intrinsic myocardial contractility and diastolic function such as positive dP/dT (1128.9 ± 398.7 vs. 806.3 ± 247.2 mmHg/s, P ˂ 0.001) and negative dP/dT (1310.7 ± 431.1 vs. 1075.1 ± 440.8 mmHg/s, P ˂ 0.001). Post‐TAVI echo showed a significant reduction in LV end‐diastolic (P = 0.036) and end‐systolic (P ˂ 0.001) diameters, improvement in LV ejection fraction (from 55 ± 12% to 57.2 ± 10.5%, P ˂ 0.001), and pulmonary artery systolic pressure (42.1 ± 14.2 vs. 33.1 ± 10.7 mmHg, P < 0.001). After a mean follow‐up time interval of 24 months, 47 patients died. Post‐TAVI significant aortic regurgitation at echocardiography was the only independent predictor of mortality (hazard ratio 5.592, confidence interval 1.932–16.184, P = 0.002). Conclusions Left heart catheterization performed immediately before and after prosthesis release offers a unique insight in the assessment of LV adaptation to severe AS and the impact of TAVI on LV, catching changes in indexes of intrinsic contractility and myocardial relaxation. Aortic regurgitation assessed by echocardiography was the only independent predictor of mortality in patients undergoing TAVI.

Abstract
Background Transcatheter aortic valve replacement (TAVR) is increasingly utilized for most patients with symptomatic severe aortic stenosis. TAVR is linked to enhanced long-term cardiac hemodynamics, reversal of left ventricle (LV) hypertrophy, and improved aortic valve gradients. We present a retrospective observational study assessing cardiac remodeling and valvular flow patterns post-TAVR. Methods Retrospective echocardiographic data were collected, evaluating cardiac function and valvular flow patterns before and after TAVR at a single institution. Data was compiled and statistically analyzed using a paired t-test evaluating variations at approximately 30 days and one-year post-TAVR. Results On echocardiogram 30 days and one-year post-TAVR, there was a reduction in LV mass index from 132 g/m² to 110 g/m² (95%CI: 98-122; p=0.01) and 118 g/m² (95%CI: 102-133; p=0.03), and a reduction in relative wall thickness from 0.54 to 0.49 (95%CI: 0.46-0.52; p=0.05) and 0.44 (95%CI: 0.38-0.49; p=0.03), respectively. Doppler velocity indices (DVI) increased from 0.24 to 0.61 (95%CI: 0.49-0.73; p<0.001) and 0.57 (95%CI: 0.48-0.65; p<0.001). Expected improvement in aortic valve velocities and gradients were observed post-TAVR. Conclusions Following TAVR, LV remodeling can be observed as early as 30 days. This is demonstrated by a reduction in LV mass index and relative wall thickness in conjugation with an anticipated improvement in valvular flow patterns and flow across the aortic valve.

Abstract
Hypo-attenuated leaflet thickening (HALT) of transcatheter aortic valves is detected on multidetector computed tomography (MDCT) and reflects leaflet thrombosis. Whether HALT affects left ventricular (LV) reverse remodeling, a favorable effect of LV afterload reduction after transcatheter aortic valve implantation (TAVI) is unknown. The aim of this study was to examine the association of HALT after TAVI with LV reverse remodeling. In this multicenter case–control study, patients with HALT on MDCT were identified, and patients without HALT were propensity matched for valve type and size, LV ejection fraction (LVEF), sex, age and time of scan. LV dimensions and function were assessed by transthoracic echocardiography before and 12 months after TAVI. Clinical outcomes (stroke or transient ischemic attack, heart failure hospitalization, new-onset atrial fibrillation, all-cause mortality) were recorded. 106 patients (age 81 ± 7 years, 55% male) with MDCT performed 37 days [IQR 32–52] after TAVI were analyzed (53 patients with HALT and 53 matched controls). Before TAVI, all echocardiographic parameters were similar between the groups. At 12 months follow-up, patients with and without HALT showed a significant reduction in LV end-diastolic volume, LV end-systolic volume and LV mass index (from 125 ± 37 to 105 ± 46 g/m2, p = 0.001 and from 127 ± 35 to 101 ± 27 g/m2, p < 0.001, respectively, p for interaction = 0.48). Moreover, LVEF improved significantly in both groups. In addition, clinical outcomes were not statistically different. Improvement in LVEF and LV reverse remodeling at 12 months after TAVI were not limited by HALT.

Abstract
AIMS Rheumatic heart disease (RHD) remains a major global health problem. Renin-angiotensin-aldosterone system inhibitors (RAASi) are commonly administered in the treatment of cardiovascular disease, but its role in RHD patients is still limited. We performed a retrospective study to determine the effect of RAASi on long-term outcomes for RHD patients. METHODS AND RESULTS A 1:1 propensity score matching was implemented to balance baseline characteristics between groups RAASi and non-RAASi. Cox proportional hazards regression model was used to investigate the associations of RAASi with the risks of all-cause mortality, cardiovascular death (CVD), and cerebrovascular death. Binary logistic regression analysis was used to evaluate the associations of RAASi with the risks of 1, 3, and 5 year heart failure (HF) rehospitalization, new-onset atrial fibrillation (AF), and new-onset stroke. A total of 734 RHD patients were enrolled as study participants; nearly half of these participants had combined valve damage (54.4%), worse New York Heart Association functional class status (III and IV, 55.2%), surgical treatment (54.2%), and AF (65.0%). After propensity score matching, 514 RHD patients were finally analysed. RAASi treatment was associated with decreased risks of all-cause mortality [adjusted hazard ratio (HR) = 0.52, 95% confidence interval (CI): 0.37-0.73, P < 0.001], CVD (adjusted HR = 0.48, 95% CI: 0.30-0.76, P = 0.002), and cerebrovascular death (adjusted HR = 0.22, 95% CI: 0.08-0.60, P = 0.003). Further subgroup analysis showed that RAASi treatment was associated with decreased risks of all-cause mortality (adjusted HR = 0.50, 95% CI: 0.31-0.79, P = 0.004), CVD (adjusted HR = 0.48, 95% CI: 0.25-0.91, P = 0.025), and cerebrovascular death (adjusted HR = 0.19, 95% CI: 0.05-0.65, P = 0.008) in RHD patients without surgical treatment, and better effect was observed in RHD patients with surgical treatment on the risks of all-cause mortality (adjusted HR = 0.47, 95% CI: 0.26-0.85, P = 0.012) and CVD (adjusted HR = 0.43, 95% CI: 0.21-0.90, P = 0.024) except cerebrovascular death (adjusted HR = 0.52, 95% CI: 0.08-3.36, P = 0.491). RAASi treatment was associated with decreased HF rehospitalization risk of 1 year [adjusted odds ratio (OR) = 0.38, 95% CI: 0.23-0.61, P < 0.001], 3 year (adjusted OR = 0.43, 95% CI: 0.28-0.68, P < 0.001), and 5 year (adjusted OR = 0.48, 95% CI: 0.30-0.77, P = 0.002) as well as new-onset AF risk (adjusted OR = 0.38, 95% CI: 0.21-0.68, P = 0.001). RAASi treatment had nothing to do with new-onset stroke risk (adjusted OR = 0.80, 95% CI: 0.47-1.38, P = 0.428). CONCLUSION Renin-angiotensin-aldosterone system inhibitor treatment was significantly associated with decreased risks of mortality, HF rehospitalization, and new-onset AF in RHD patients in median 5.9 year follow-up.

[PMID: 34416227 DOI: 10.1016/j.athoracsur.2021.07.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 06/11/2021] [Accepted: 07/08/2021] [Indexed: 11/01/2022]
Abstract
BACKGROUND Differences in left ventricular mass regression (LVMR) between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) have not been studied. We present clinical and echocardiographic data from veterans who underwent TAVR and SAVR, evaluating the degree of LVMR and its association with survival. METHODS We retrospectively reviewed TAVR (n = 194) and SAVR (n = 365) procedures performed in veterans from 2011 to 2019. After 1:1 propensity matching, we evaluated mortality and secondary outcomes. Echocardiographic data (median follow-up 957 days, interquartile range 483-1652 days) were used to evaluate LVMR, its association with survival, and predictors of LVMR. RESULTS There was no difference between SAVR and TAVR patients in mortality (for up to 8 years), stroke at 30 days, myocardial infarction, renal failure, prolonged ventilation, reoperation, or structural valve deterioration. SAVR patients (67.3% [101 of 150]) were more likely to have LVMR than TAVR patients (55.7% [44 of 79], P = .11). The magnitude of LVMR was greater for the SAVR patients (median, -23.3%) than for the TAVR patients (median, -17.8%, P = .062). SAVR patients with LVMR had a survival advantage over SAVR patients without LVMR (P = .016). However, LVMR was not associated with greater survival in TAVR patients (P = .248). CONCLUSIONS SAVR patients were more likely to have LVMR and had a greater magnitude of LVMR than TAVR patients. LVMR was associated with better survival in SAVR patients, but not in TAVR patients.

Incidence, Predictors, and Prognostic Impact of Immediate Improvement in Left Ventricular Systolic Function After Transcatheter Aortic Valve Implantation. Am J Cardiol 2021; 152:99-105. [PMID: 34127247 DOI: 10.1016/j.amjcard.2021.04.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Revised: 04/15/2021] [Accepted: 04/20/2021] [Indexed: 10/21/2022]
Abstract
Immediate improvement in left ventricular ejection fraction (LVEF) following transcatheter aortic valve implantation (TAVI) is common; however, data on the pattern and prognostic value of this improvement are limited. To evaluate the incidence, predictors, and clinical impact of immediate improvement in LVEF, we studied 694 consecutive patient who had underwent successful TAVI for severe aortic stenosis (AS) between March 2010 and December 2019. We defined immediate improvement of LVEF as an absolute increase of ≥5% in LVEF at post-procedure echocardiogram. The primary outcome was major adverse cardiac or cerebrovascular event (MACCE), defined as a composite of death from cardiovascular cause, myocardial infarction, stroke, or rehospitalization from cardiovascular cause. Among them, 160 patients showed immediate improvement in LVEF. The independent predictors of immediate LVEF improvement were absence of hypertension and baseline significant aortic regurgitation, and greater baseline LV mass index. Immediate improvement in LVEF was significantly associated with a lower risk of MACCE (adjusted hazard ratio, 0.48; 95% confidence interval, 0.28-0.81; p = 0.01). In conclusion, approximately one-fourth of patients with severe AS who underwent TAVI showed immediate improvement in LVEF during index hospitalization. Immediate LVEF recovery was associated with a lower risk of MACCE during follow-up.

High Post-Procedural Transvalvular Gradient or Delayed Mean Gradient Increase after Transcatheter Aortic Valve Implantation: Incidence, Prognosis and Associated Variables. The FRANCE-2 Registry. J Clin Med 2021; 10:jcm10153221.

Abstract
Mean Gradient (MG) elevation can be detected immediately after transcatheter aortic valve implantation (TAVI) or secondarily during follow-up. Comparisons and interactions between these two parameters and their impact on outcomes have not previously been investigated. This study aimed to identify incidence, influence on prognosis, and parameters associated with immediate high post-procedural mean transvalvular gradient (PPMG) and delayed mean gradient increase (6 to 12 months after TAVI, DMGI) in the FRANCE 2 (French Aortic National CoreValve and Edwards 2) registry. The registry includes all consecutive symptomatic patients with severe aortic stenosis who have undergone TAVI. Three groups were analyzed: (1) PPMG < 20 mmHg without DMGI > 10 mmHg (control); (2) PPMG < 20 mmHg with DMGI > 10 mmHg (Group 1); and (3) PPMG ≥ 20 mmHg (Group 2). From January 2010 to January 2012, 4201 consecutive patients were prospectively enrolled in the registry. Controls comprised 2078 patients. In Group 1(n = 131 patients), DMGI exceeded 10 mmHg in 5.6%, and was not associated with greater 4-years mortality than in controls (32.6% vs. 40.1%, p = 0.27). In Group 2 (n = 144 patients), PPMG was at least 20 mmHg in 6.1% and was associated with higher 4-year mortality (48.7% versus 40.1%, p = 0.005). A total of two-thirds of the patients with PPMG ≥ 20 mmHg had MG < 20 mmHg at 1 year, with mortality similar to the controls (39.2% vs. 40.1%, p = 0.73). Patients with PPMG > 20 mmHg 1 year post-TAVI had higher 4-years mortality than the general population of the registry, unlike patients with MG normalization.

Abstract
Background With the expanded utilization of transcatheter aortic valve implantation (TAVI) to younger and lower surgical risk patients with severe aortic stenosis (AS), optimal medical therapy after TAVI procedure has become the main concern. Renin-angiotensin system inhibitors (RASi) are widely utilized in the area of cardiovascular disease including heart failure and myocardial infarction and revealed the ability to reverse left ventricular (LV) remodeling. Interests have, thus, been drawn in investigating whether the prescription of RASi after the TAVI procedure can prevent or reverse cardiac remodeling and improve long-term clinical outcomes. No recommendation regarding the prescription of RASi after TAVI is proposed yet due to the lack of evidence from randomized controlled trials, especially in the Chinese population. We, therefore, designed this randomized controlled trial to explore the effect of adding fosinopril to standard care in patients who underwent a successful TAVI procedure on the LV remodeling. Methods A total of 200 post-TAVI patients from seven academic hospitals across China will be recruited and randomized with a ratio of 1:1 to receive standard care or standard care plus fosinopril. Follow-up visits will take place at 30 days, 3 months, 6 months, 12 months, and 24 months from randomization to assess the clinical symptoms, any adverse events, cardiac function, and quality of life. Cardiac magnetic resonance will be performed at baseline and repeated at the 24-month follow-up visit to assess LV remodeling. Discussion This study will provide evidence regarding medical therapy for AS patients who underwent TAVI and filling the gap in the Chinese population.

Abstract
Introduction: Over the past decade, the number of transcatheter aortic valve replacement (TAVR) procedures has increased exponentially. Despite major improvements in both device and successes, the rate of hospital readmission after TAVR remains high, with heart failure (HF) decompensation being one of the most important causes.Areas covered: This review provides an overview of the current status of HF following TAVR, including details about its incidence, clinical impact, contributing factors, and current and future treatment perspectives.Expert opinion: HF decompensation has been identified as the most common cause of rehospitalization following TAVR, and it has been associated with a negative prognosis. Multiple preexisting factors including low flow status, cardiac amyloidosis, myocardial fibrosis, multivalvular disease, pulmonary hypertension, coronary artery disease, and atrial fibrillation have been associated with an increased risk of HF events. Also, multiple post-procedural factors like the occurrence of significant paravalvular leaks, severe prosthesis-patient mismatch, and conduction disturbances have also contributed to increase this risk . Thus, reducing HF events in TAVR recipients would require a multifactorial and multidisciplinary effort including the optimization of the medical treatment and close follow-up and treatment of residual or concomitant valvular disease and conduction disturbance issues. Future studies in this challenging group of patients are warranted.

Abstract
BACKGROUND Left ventricular noncompaction cardiomyopathy (LVNC) is characterized by prominent ventricular trabeculations on cardiovascular imaging. Acquired reversible LVNC has not been reported in pediatrics without a genetic background. CASE PRESENTATION A 9-year-old girl with a ventriculoperitoneal (VP) shunt for neonatal posthemorrhagic hydrocephalus was referred due to exacerbation of hydrocephalus caused by VP shunt dysfunction. Transthoracic echocardiography (TTE) revealed depressed left ventricular (LV) systolic function and thick prominent trabeculae in the LV, predominantly in the apex, suggesting LVNC. Following treatment with extraventricular drainage for hydrocephalus, prominent trabeculation of the LV was diminished on TTE within 3 months. Genetic testing using next-generation sequencing was performed, and no significant variants were identified. CONCLUSIONS We revealed for the first time a pediatric case of reversible LVNC without genetic predisposition. This case report provides valuable information on the pathogenesis of acquired LVNC and suggests that detailed evaluation is required to elucidate the diagnosis of this wide spectrum of etiologic-pathogenetic disorders.

Abstract
BACKGROUND The effect of sex on mortality is controversial; furthermore, sex differences in left ventricular (LV) remodeling after transcatheter aortic valve implantation (TAVI) remain unknown.Methods and Results:This study included 2,588 patients (1,793 [69.3%] female) enrolled in the Optimized CathEter vAlvular iNtervention (OCEAN)-TAVI Japanese multicenter registry between October 2013 and May 2017. We retrospectively analyzed the effect of sex on mortality, and evaluated changes in the LV mass index (LVMI) after TAVI. Female sex was significantly associated with lower all-cause and cardiovascular mortality (log-rank P<0.001 for both). Multivariate analysis showed that female sex was independently associated with lower cumulative long-term mortality (hazard ratio 0.615; 95% confidence interval 0.512-0.738; P<0.001). Regression in the LVMI was observed in both sexes, and there was no significant difference in the percentage LVMI regression from baseline to 1 year after TAVI between women and men. Women had a survival advantage compared with men among patients with LVMI regression at 1 year, but not among patients with no LVMI regression. CONCLUSIONS We found that female sex is associated with better survival outcomes after TAVI in a large Japanese registry. Although LVMI regression was observed in women and men after TAVI, post-procedural LV mass regression may be related to the sex differences in mortality.

Abstract
BACKGROUND Calcific aortic valve disease (CAVD) is a rapidly growing global health problem with an estimated 12.6 million cases globally in 2017 and a 112% increase of deaths since 1990 due to aging and population growth. CAVD may develop into aortic stenosis (AS) by progressive narrowing of the aortic valve. AS is underdiagnosed, and if treatment by aortic valve replacement (AVR) is delayed, this leads to poor recovery of cardiac function, absence of symptomatic improvement and marked increase of mortality. Considering the current limitations to define the stage of AS-induced cardiac remodeling, there is need for a novel method to aid in the diagnosis of AS and timing of intervention, which may be found in metabolomics profiling of patients. METHODS Serum samples of nine healthy controls and 10 AS patients before and after AVR were analyzed by untargeted mass spectrometry. Multivariate modeling was performed to determine a metabolic profile of 30 serum metabolites which distinguishes AS patients from controls. Human cardiac microvascular endothelial cells (CMECs) were incubated with serum of the AS patients and then stained for ICAM-1 with Western Blot to analyze the effect of AS patient serum on endothelial cell activation. RESULTS The top 30 metabolic profile strongly distinguishes AS patients from healthy controls and includes 17 metabolites related to nitric oxide metabolism and 12 metabolites related to inflammation, in line with the known pathomechanism for calcific aortic valve disease. Nine metabolites correlate strongly with left ventricular mass, of which three show reversal back to control values after AVR. Western blot analysis of CMECs incubated with AS patient sera shows a significant reduction (14%) in ICAM-1 in AS samples taken after AVR compared to AS patient sera before AVR. CONCLUSION Our study defined a top 30 metabolic profile with biological and clinical relevance, which may be used as blood biomarker to identify AS patients in need of cardiac surgery. Future studies are warranted in patients with mild-to-moderate AS to determine if these metabolites reflect disease severity and can be used to identify AS patients in need of cardiac surgery.

Prognostic impact of left ventricular mass regression after transcatheter aortic valve replacement in patients with left ventricular hypertrophy. Int J Cardiol 2021; 332:60-66. [PMID: 33781852 DOI: 10.1016/j.ijcard.2021.03.053] [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: 01/22/2021] [Revised: 02/23/2021] [Accepted: 03/22/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Paravalvular regurgitation (PVR) has been known to be the primary determinant of poor left ventricular (LV) mass regression after transcatheter aortic valve replacement (TAVR). However, the incidence of significant PVR has been reduced considerably as TAVR technology evolved rapidly. This study aimed to investigate the time course and impact of LV mass index (LVMi) regression on long-term clinical outcomes in severe aortic stenosis (AS) patients without significant PVR after TAVR. METHODS Of 412 patients who underwent TAVR, 146 who had LV hypertrophy (LVMi ≥115 g/m2 for men and ≥ 95 g/m2 for women) at baseline and were alive at one year after TAVR were enrolled. The primary outcome was cardiovascular deaths and the impact of LVMi regression on clinical outcomes were examined. The patients with significant PVR were excluded. RESULTS During a median follow-up of 40 months (interquartile range, 26-58 months), 9 (6.2%) cardiovascular deaths, 21 (14.4%) all-cause deaths, and 9 (6.2%) hospitalizations occurred. In the multivariable analysis, the percentage change of LVMi was an independent predictor of cardiovascular deaths (adjusted hazard ratio [HR], 1.03; 95% confidential interval [CI], 1.01-1.05; P = 0.010), and composite outcome of cardiovascular deaths and rehospitalization for heart failure (adjusted HR, 1.02; 95% CI, 1.00-1.04; P = 0.022). Baseline LVMi, eccentric hypertrophy, and TAVR-induced left bundle branch block were independently associated with LVMi regression. CONCLUSIONS In patients with severe AS who received successful TAVR without significant PVR, the degree of LVMi regression is an independent predictor of postoperative outcomes after TAVR.

Abstract
INTRODUCTION This study aims to investigate the correlation between severe aortic stenosis (sAS) and impairment of left ventricular global longitudinal strain (LVGLS) in particular segments, using two-dimensional speckle tracking echocardiography in patients with sAS and normal ejection fraction of left ventricle (LVEF). METHODS The study included 53 consecutive patients with asymptomatic sAS and preserved LVEF. The regional longitudinal systolic LV wall strain was evaluated at the area opposite of the aorta as the median strain value of the basal, middle, and apical segments of the lateral and posterior walls and was compared to the average strain value of the interventricular septum (IVS) at the same views. RESULTS LVGLS was decreased and was not statistically different between three- and four-chamber views (-12.5 ± 3.6 vs -11.4 ± 5.5%, p = 0.2). The average strain values of the lateral and posterior walls were statistically reduced compared to the average value of the IVS (lateral vs IVS: -7.8 ± 3.7 vs -10 ± 5.3%, p = 0.005, posterior vs IVS: -7.7 ± 4.2 vs -10.3 ± 3.8%, p < 0.0001). There was no significant difference between lateral and posterior walls (-7.8 ± 3.7 vs -7.7 ± 4.2%, p = 0.9). CONCLUSIONS The strain of lateral and posterior walls of left ventricle, which lay just opposite to the aortic valve seem to be more reduced compared to other walls in patients with sAS and preserved LVEF possibly due to their anatomical position. This impairment seems to be the reason of the overall LVGLS reduction. Regional strain could be used as an extra tool for the estimation of the severity of AS as well as for prognostic information in asymptomatic patients.

Abstract
Background In patients undergoing transcatheter aortic valve replacement (TAVR), those with small left ventricle (LV) may have an increased risk of poor outcomes, because small LV is associated with low‐flow (LF), left ventricular hypertrophy. However, the impact of small LV on patients undergoing TAVR remains unknown. Methods and Results We examined 2584 patients who underwent TAVR between October 2013 and May 2017 using data from the Japanese multicenter registry. On the basis of the American Society of Echocardiography guidelines, small LV was defined as left ventricular end‐diastolic dimension <42.0 mm for men or <37.8 mm for women. The 2‐year clinical outcomes were compared between patients with and without small LV using multivariable Cox regression analyses and propensity score matching. Subgroup analyses by LF, left ventricular hypertrophy were performed. Of 2584 patients who underwent TAVR, 466 (18.0%) had small LV. Patients with small LV had smaller body size and less comorbidity, and were more likely to have LF status compared with those without. Small LV was associated with a higher 2‐year all‐cause (20.8% versus 14.3%; adjusted hazard ratio [HR],1.58 [95% CI, 1.20–2.09]; P=0.0013) and cardiovascular mortality (8.8% versus 5.5%; adjusted HR, 1.93 [95% CI, 1.25–2.98]; P=0.0028). Propensity score matching analysis showed consistent findings. In subgroup analyses, LF, left ventricular hypertrophy did not interact with small LV. Conclusions Small LV, determined by a simple echocardiographic parameter, was associated with poorer clinical outcomes after TAVR regardless of LF, left ventricular hypertrophy. LV size may be useful for assessing clinical outcomes after TAVR. Registration URL: https://www.umin.ac.jp/ctr/index.htm; Unique identifier: UMIN000020423.

Abstract
AIMS Atrial fibrillation (AF) is associated with increased mortality after transcatheter aortic valve replacement (TAVR). Cerebrovascular complications and bleeding events associated with anticoagulation therapy are discussed to be possible causes for this increased mortality. The present study sought to assess whether AF is associated with impaired left ventricular (LV) reverse remodeling representing another possible mechanism for poor outcome. METHODS All patients who underwent TAVR in our institution and had 1-year echocardiography follow-up were included. LV mass index (LVMI) at baseline and follow-up as well as LVMI change at 1 year were assessed with respect to the presence of AF (either at baseline or during hospitalization after TAVR) and sinus rhythm (SR). RESULTS A total of 213 patients (n = 95 in AF; n = 118 in SR) were enrolled in the present study. Patients with AF had higher LVMI at 1 year compared to those with SR (173 ± 61 g/m2 vs. 154 ± 55 g/m2; p = 0.02) and they showed lower relative LVMI change at 1 year (- 2 ± 28% vs. - 9 ± 29%; p = 0.04). In linear regression analysis, AF was independently associated with relative LVMI change (regression coefficient ß 0.076 [95% CI 0.001-0.150]; p = 0.04). With respect to clinical outcome depending on AF and LVMI regression, the Kaplan-Meier estimated event-free of death or cardiac rehospitalization at 3 years was lowest among patients with AF and no LVMI regression. CONCLUSIONS The present study identified a significant association of AF with changes in LVMI after TAVR, which was also shown to be associated with clinical outcome.

Abstract
The impact of reverse left ventricular remodeling (r-LVR) on clinical outcomes after surgical correction of anomalous left coronary artery from the pulmonary artery (ALCAPA) remains unclear. This study aims to examine the prognostic significance of r-LVR in patients with ALCAPA after surgery. We prospectively identified 61 patients undergoing surgical correction for ALCAPA; 54 patients had adequate echocardiographic image quality with quantitative biplane analysis performed both at baseline and at 30-day postoperative follow-up. Postoperative r-LVR was defined as a reduction of ≥ 10% in left ventricular end-diastolic volume index during follow-up. Cox proportional-hazards regression was used to investigate the independent association of r-LVR and all-cause mortality. Among 54 patients (age: 21.2 ± 7 months; 37% females), r-LVR occurred in 35 patients (64.8%) after surgery. Compared to patients with r-LVR, patients without r-LVR had significantly higher level of N-terminal pro B-type natriuretic peptide (NT-proBNP) [2176 (711, 4219) vs 998 (623, 2145) P < 0.001] and lower survival rate (47.3% vs 82.9%, HR = 5.72 [1.96 to 17.20], P < 0.001) at 1-year follow-up. NT-proBNP (OR = 2.27 [1.67 to 18.3], P = 0.02) was an independent predictor of r-LVR in multivariate analysis. Moreover, r-LVR was significantly associated with a lower rate of all-cause mortality (HR = 0.27 [0.08 to 0.98], P = 0.03) in multivariate analysis, even after adjustment for clinical and echocardiographic variables. R-LVR occurred in more than half of patients with ALCAPA undergoing surgical correction and it was associated with better clinical outcomes. NT-proBNP is an independent predictor of r-LVR.

Abstract
BACKGROUND Increased left ventricular (LV) afterload in patients with aortic stenosis consists of valvular and vascular loads; however, the effects of vascular load induced by arterial stiffness on clinical outcomes after transcatheter aortic valve replacement (TAVR) remain unclear. This study evaluated the prognostic value of brachial-ankle pulse wave velocity (baPWV) after TAVR. METHODS A retrospective study including 161 consecutive patients who underwent TAVR with a pre-procedural baPWV assessment was conducted. We investigated the association between baPWV and the 1-year composite outcome comprising all-cause death and rehospitalization related to heart failure. Echocardiographic measurements including the LV mass index (LVMi) and LV diastolic function at 1, 6, and 12 months after TAVR were assessed. RESULTS Of the 161 patients, 31 patients experienced composite outcome within 1 year after TAVR. The receiver operating characteristic curve analysis revealed that the discriminating baPWV level to discern 1-year composite outcome was 1,639 cm/s, and all subjects were allocated to two groups based on the result. Baseline characteristics were comparable between the high baPWV (n = 72) and low baPWV groups (n = 89). The Kaplan-Meier curve revealed a significantly higher cumulative 1-year composite outcome in the high baPWV group than in the low baPWV group (31% vs. 10%; log-rank test, p<0.001). High baPWV was an independent predictor of the 1-year composite outcome (adjusted hazard ratio, 3.42; 95% confidence interval, 1.62-7.85; p = 0.002). Furthermore, post-procedural echocardiography revealed that the high baPWV group had less LVMi regression and higher E/e' after TAVR compared to the low baPWV group. The delayed reversal in LVMi and diastolic function attributable to arterial stiffness might be linked to impaired clinical outcomes after TAVR. CONCLUSIONS Higher baPWV could be associated with adverse clinical outcomes and delayed reverse LV remodeling after TAVR.

Abstract
INTRODUCTION Transcatheter aortic valve implantation (TAVI) is a widely used treatment option as an alternative to surgical aortic valve replacement in patients with severe aortic stenosis (AS) at high or intermediate surgical risk. TAVI improves symptoms, induces reverse left ventricular (LV) remodelling and increases overall survival. However, a careful patient selection is essential to achieve better outcome. Evidence on LV functional recovery and LV mass regression after TAVI based on contemporary registry data is scarce. The impact of TAVI on the arterial vasculature is also less explored. METHOD AND ANALYSES This is a study of 600 consecutive patients with AS who underwent a TAVI at Haukeland University Hospital, Bergen, Norway. Demographics, clinical data, arterial haemodynamics and echocardiographic parameters were prospectively collected. In the present paper, we describe the design, major scientific objectives and echocardiography imaging protocol of the TAVI-NOR (TAVI in western NORway) study. The main objectives are: To explore the impact of TAVI on cardiac structure and function in patients with severe AS, identify the echocardiographic predictors of reverse LV remodelling, assess survival benefits according to baseline risk profile, evaluate long-term therapeutic success as reflected by reduction in valvular-arterial impedance and to investigate the impact of various types of blood pressure response immediately after TAVI on clinical outcome. ETHICS AND DISSEMINATION The study was approved by the Regional Committees for Medical and Health Research Ethics (REK vest, ref. number 33814) and the Institutional Data Protection Services. Patients' consent was waived. The study findings will be disseminated via peer-reviewed publications and presentation in national and international scientific meetings and conferences. TRAIL REGISTRATION NUMBER The study was registered in the international database: ClinicalTrials.gov, Identifier: NCT04417829.

Abstract
Background It is unclear whether increased left ventricular (LV) thickness is associated with worse clinical outcomes in severe aortic stenosis (AS). The aim of this study was to determine the effect of increased LV wall thickness (LVWT) on major clinical outcomes in patients with severe AS. Methods and results This study included 290 severe AS patients (mean age 69.4 ± 11.0 years; 136 females) between January 2008 and December 2018. For outcome assessment, the endpoint was defined as death from all causes, cardiovascular death, and the aortic valve replacement (AVR) surgery rate. During follow-up (48.7 ± 39.0 months), 157 patients had AVR, 43 patients died, and 28 patients died from cardiovascular causes. Patients with increased LVWT underwent AVR surgery much more than those without LVWT (60.0% vs. 39.0%, p < 0.001). Furthermore, in patients with increased LVWT, the all-cause and cardiovascular death rates were significantly lower in the AVR group than in the non-AVR group (8.8% vs. 27.3%, p < 0.001, 4.8%, vs. 21.0%, p < 0.001). Multivariate analysis revealed that increased LVWT, age, dyspnea, and AVR surgery were significantly correlated with cardiovascular death. Conclusions In patients with severe AS, increased LVWT was associated with a higher AVR surgery rate and an increased rate of cardiovascular death independent of other well-known prognostic variates. Thus, these findings suggest that increased LVWT might be used as a potential prognostic factor in severe AS patients.

Abstract
OBJECTIVES We aimed to evaluate the impact of renin-angiotensin system (RAS) inhibitors on outcomes after transcatheter aortic valve replacement (TAVR). BACKGROUND The impact of RAS inhibitors on outcomes after TAVR was unclear. METHODS A systematic review of articles comparing outcomes of patients using and not using RAS inhibitors after TAVR was performed through PubMed, Embase, and Cochrane. Primary outcome was midterm all-cause mortality. Risk ratios (RRs) were calculated with the corresponding 95% confidence interval using random effect models. RESULTS Five studies with 23,319 patients were included. Patients treated with RAS inhibitors had lower midterm all-cause mortality after TAVR than those without RAS inhibitors in both the unmatched (13.3 vs. 17.2%, RR 0.77, p = .005) and propensity score matched cohorts (13.5 vs 16.2%, RR 0.83, p < .001). Cardiovascular mortality (10.4 vs. 15.6%, RR 0.68, p < .001), rate of heart failure readmission (12.2 vs. 14.5%, RR 0.80, p = .006), and new-onset atrial fibrillation (14.0 vs. 23.7%, RR 0.73, p = .003) were also lower with RAS inhibitors. No difference was found between two groups regarding cerebrovascular events, myocardial infarction, major bleeding, major vascular complications, acute kidney injury, permanent pacemaker implantation, and moderate/severe paravalvular aortic regurgitation. CONCLUSIONS RAS inhibitors were associated with lower midterm all-cause mortality after TAVR.

Abstract
Importance Among those with aortic stenosis, natriuretic peptide levels can provide risk stratification, predict symptom onset, and aid decisions regarding the timing of valve replacement. Less is known about the prognostic significance and potential clinical utility of natriuretic peptide levels measured after valve replacement. Objective To determine the associations of elevated B-type natriuretic peptide (BNP) levels after transcatheter aortic valve replacement (TAVR) and change in BNP levels between follow-up time points with risk of subsequent clinical outcomes. Design, Setting, and Participants In this cohort study, patients with severe symptomatic aortic stenosis at intermediate, high, or prohibitive surgical risk for aortic valve replacement who underwent TAVR from the PARTNER IIA cohort, PARTNER IIB cohort, SAPIEN 3 intermediate-risk registry, and SAPIEN 3 high-risk registry were included. B-type natriuretic peptide levels were obtained at baseline and discharge as well as 30 days and 1 year after TAVR. For each measurement, a BNP ratio was calculated using measured BNP level divided by the upper limit of normal for the assay used. Outcomes were evaluated in landmark analyses out to 2 years. Data were collected from April 2011 to January 2019. Main Outcomes and Measures All-cause death, cardiovascular death, rehospitalization, and the combined end point of cardiovascular death or rehospitalization. Results Among 3391 included patients, 1969 (58.1%) were male, and the mean (SD) age was 82 (7.5) years. Most patients had a BNP ratio greater than 1 at each follow-up time point, including 2820 of 3256 (86.6%) at baseline, 2652 of 2995 (88.5%) at discharge, 1779 of 2209 (80.5%) at 30 days, and 1799 of 2391 (75.2%) at 1 year. After adjustment, every 1-point increase in BNP ratio at 30 days (approximately equivalent to an increase of 100 pg/mL in BNP) was associated with an increased hazard of all-cause death (adjusted hazard ratio [aHR], 1.11; 95% CI, 1.07-1.15), cardiovascular death (aHR, 1.16; 95% CI, 1.11-1.21), and rehospitalization (aHR, 1.08; 95% CI, 1.03-1.14) between 30 days and 2 years. Among those with a BNP ratio of 2 or more at discharge, after adjustment, every 1-point decrease in BNP ratio between discharge and 30 days was associated with a decreased hazard of all-cause death (aHR, 0.92; 95% CI, 0.88-0.96) between 30 days and 2 years. Conclusions and Relevance Elevated BNP levels after TAVR was independently associated with increased subsequent mortality and rehospitalizations. Further studies to determine how best to mitigate this risk are warranted.

Subclinical leaflet thrombosis is associated with impaired reverse remodelling after transcatheter aortic valve implantation. Eur Heart J Cardiovasc Imaging 2020; 21:1144-1151.

Abstract
AIMS Cardiac CT is increasingly applied for planning and follow-up of transcatheter aortic valve implantation (TAVI). However, there are no data available on reverse remodelling after TAVI assessed by CT. Therefore, we aimed to evaluate the predictors and the prognostic value of left ventricular (LV) reverse remodelling following TAVI using CT angiography. METHODS AND RESULTS We investigated 117 patients with severe, symptomatic aortic stenosis (AS) who underwent CT scanning before and after TAVI procedure with a mean follow-up time of 2.6 years after TAVI. We found a significant reduction in LV mass (LVM) and LVM indexed to body surface area comparing pre- vs. post-TAVI images: 180.5 ± 53.0 vs. 137.1 ± 44.8 g and 99.7 ± 25.4 vs. 75.4 ± 19.9 g/m2, respectively, both P < 0.001. Subclinical leaflet thrombosis (SLT) was detected in 25.6% (30/117) patients. More than 20% reduction in LVM was defined as reverse remodelling and was detected in 62.4% (73/117) of the patients. SLT, change in mean pressure gradient on echocardiography and prior myocardial infarction was independently associated with LV reverse remodelling after adjusting for age, gender, and traditional risk factors (hypertension, body mass index, diabetes mellitus, and hyperlipidaemia): OR = 0.27, P = 0.022 for SLT and OR = 0.22, P = 0.006 for prior myocardial infarction, OR = 1.51, P = 0.004 for 10 mmHg change in mean pressure gradient. Reverse remodelling was independently associated with favourable outcomes (HR = 0.23; P = 0.019). CONCLUSION TAVI resulted in a significant LVM regression on CT. The presence of SLT showed an inverse association with LV reverse remodelling and thus it may hinder the beneficial LV structural changes. Reverse remodelling was associated with improved long-term prognosis.

J Clin Med 2020; 9:jcm9103143.

Abstract
Increase in left ventricular (LV) mass develops as a compensatory mechanism against pressure overload in aortic valve stenosis. However, long-standing LV geometrical changes are related to poor prognosis. The LV geometrical change occurs after transcatheter aortic valve replacement (TAVR). The present study aimed to investigate the relationship between improvement in valvuloarterial impedance (Zva) and change in LV mass index (LVMI) and the ratio of LVMI to LV end-diastolic volume index (LVMI/LVEDVI). We compared these relationships to that between Zva and mean pressure gradient (MPG). Baseline and follow-up transthoracic echocardiograms of 301 patients who underwent TAVR from November 2011 to December 2015 were reviewed. Spearman correlation coefficient (ρ) was used to compare ΔLVMI and ΔLVMI/LVEDVI with Zva or MPG. The correlation between ΔZva and ΔLVMI (ρ = 0.47, p < 0.001) was superior to that between ΔMPG and ΔLVMI (ρ = 0.15, p = 0.009) (p for comparison < 0.001). The correlation between ΔZva and ΔLVMI/LVEDVI was statistically significant (ρ = 0.54, p < 0.001); in contrast, that of ΔMPG and ΔLVMI/LVEDVI was not. The improvement in Zva after TAVR was more closely related to LVMI and LVMI/LVEDVI reduction than MPG reduction.

Abstract
The use of LDT may signify significant hemodynamic changes and left ventricular remodeling in severe aortic stenosis (AS). Therefore, we sought to determine whether loop diuretic therapy (LDT) is associated with adverse outcomes following transcatheter aortic valve implantation (TAVI) in patients with severe symptomatic AS. Subjects undergoing TAVI at a single institution from June 2008 to December 2017 were analyzed. LDT doses were normalized to oral furosemide daily equivalents. All outcomes were adjudicated using VARC2 criteria. Descriptive statistics, multivariate logistic regression, and propensity score matching were used. Of the 804 subjects studied, 48.3% were on pre-TAVI LDT with a mean dose of 51.1 mg furosemide dose-equivalents. Subjects on LDT were higher risk, frail patients with more co-morbidities including chronic kidney disease, coronary artery disease requiring prior bypass grafting, peripheral arterial disease, atrial fibrillation or flutter, and diabetes with more severe heart failure symptoms. Those on LDT also had worse left ventricular systolic function, lower transvalvular gradients, and markers of adverse left ventricular remodeling, including increased left ventricular mass index and higher rates of concentric and eccentric hypertrophy. On propensity-score matching, death within one year post-TAVI was borderline significantly higher in the pre-LDT as compared with no-LDT group (16.9% vs 10.4 %, p = 0.068). In conclusion, use of pre-TAVI LDT for severe symptomatic AS is associated with a trend towards worse 1-year mortality and is a marker of high-risk, frail individuals with advanced left ventricular remodeling.

Abstract
Aortic stenosis (AS) is a common valvular heart disease in the aging population that is characterized by a variable period of asymptomatic phase before development of symptoms and severe AS. Mortality and morbidity is substantial even after aortic valve replacement, in part related to persistent left ventricular hypertrophy, diastolic dysfunction, and heart failure. Renin-angiotensin system (RAS) blockade therapy is associated with modulation of adverse left ventricular remodeling, reduction in myocardial hypertrophy, and fibrosis, resulting in clinical improvements in patients with congestive heart failure There are emerging data to suggest benefit of RAS blockade in patients with AS before and after AVR with regard to potentially slower progression of aortic valve calcification, left ventricular mass and survival benefit in favor of RAS blockade group before AVR, and also survival benefit in patients after AVR. We review the available data to understand the role of RAS blockade before AVR and in patients undergoing surgical AVR and transcatheter AVR. There are significant survival advantages of RAS inhibition in patients with AS undergoing surgical AVR or transcatheter AVR. On the basis of existing literature, adequately powered randomized trials are needed to evaluate the role of RAS inhibition in patients with AS.

Abstract
Since the introduction of transcatheter aortic valve replacement (TAVR), there has been a paradigm shift in the management of severe aortic stenosis. While women represent almost half of the patients undergoing TAVR, there are limited data on sex-based comparisons in hospital outcomes and predictors of mortality in women and men. The National Inpatient Sample database from 2012 to 2015 was used to identify TAVR using international classification of diseases-9 clinical modification procedure codes 35.05 and 35.06. We identified 61,239 patients who underwent TAVR between 2012 and 2015. After adjusting for potential confounders, women had higher odds of all-cause mortality as compared to men [odds ratio (OR) 1.25, 95% confidence interval (CI): 1.01-1.54; P = 0.036]. Moreover, women had significantly increased odds of cardiac complications [OR 2.41, 95% CI: 1.67-3.49; P ≤ 0.01], respiratory complications [OR 1.20 95% CI: 1.07-1.34; P = 0.001], major hemorrhage requiring transfusion [OR 1.51, 95% CI: 1.37-1.67; P ≤ 0.001], neurological complications [OR 1.38, 95% CI: 0.95-1.99; P = 0.08], need for vasopressor treatment [OR 1.33, 95% CI: 1.01-1.75; P = 0.04], and vascular complications [OR 1.73, 95% CI: 1.19-2.52; P = 0.004]. On the contrary, the odds of pacemaker requirement [OR 0.85, 95% CI: 0.75-0.97; P = 0.02], and acute kidney injury [OR 0.80, 95% CI: 0.71-0.91; P = 0.001] were significantly lower in women. Among patients undergoing TAVR, women were more likely to have in-hospital complications and mortality as compared with men. Further studies are needed to identify the discrepancy in in-hospital outcomes with sex-specific factors being considered.

Abstract
BACKGROUND There is growing body of evidence from retrospective studies that renin-angiotensin system (RAS) blockade is associated with improved outcome after transcatheter aortic valve replacement (TAVR). However, it remains unknown whether the effect of RAS blockade is dose dependent. The current study sought to assess the dose-dependent effect of RAS blockade on survival and left-ventricular (LV) remodelling after TAVR. METHODS Patients who were enrolled into our observational TAVR study at our institution were retrospectively assessed according to different doses of RAS blockade: group 1 (no RAS blockade), group 2 (25% of maximum daily dose), group 3 (50% of maximum daily dose), and group 4 (full daily dose). RESULTS A total of 323 patients between January 2015 and September 2019 were included. Patients with higher doses of RAS blockade showed a trend toward higher overall survival at 3-year follow-up (56% with no RAS blockade vs 66% with the 25% dose vs 79% with the 50% dose vs 78% with the full dose; P = 0.063). After adjustment for baseline characteristics, the difference in survival was significant (P = 0.042). Besides New York Heart Association class and left-ventricular ejection fraction (LVEF), RAS blockade dose was identified as independent predictor for all-cause mortality (hazard ratio [HR] 0.72; 95% confidence interval [CI], 0.54-0.97; P = 0.03). With respect to LV remodelling, a significantly larger reduction of LV mass index was observed during the follow-up with higher doses of RAS blockade. CONCLUSIONS The current study showed that the impact of RAS blockade treatment on clinical outcome and LV remodelling after TAVR is dose dependent.

[PMID: 31857020 DOI: 10.1016/j.jcin.2019.09.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Revised: 08/15/2019] [Accepted: 09/05/2019] [Indexed: 12/25/2022]
Abstract
OBJECTIVES The aim of this study was to investigate the prognostic impact of the decline in left ventricular ejection fraction (LVEF) at 1-year follow-up in patients with severe aortic stenosis (AS) managed conservatively. BACKGROUND No previous study has explored the association between LVEF decline during follow-up and clinical outcomes in patients with severe AS. METHODS Among 3,815 patients with severe AS enrolled in the multicenter CURRENT AS (Contemporary Outcomes After Surgery and Medical Treatment in Patients With Severe Aortic Stenosis) registry in Japan, 839 conservatively managed patients who underwent echocardiography at 1-year follow-up were analyzed. The primary outcome measure was a composite of AS-related deaths and hospitalization for heart failure. RESULTS There were 91 patients (10.8%) with >10% declines in LVEF and 748 patients (89.2%) without declines. Left ventricular dimensions and the prevalence of valve regurgitation and atrial fibrillation or flutter significantly increased in the group with declines in LVEF. The cumulative 3-year incidence of the primary outcome measure was significantly higher in the group with declines in LVEF than in the group with no decline (39.5% vs. 26.5%; p < 0.001). After adjusting for confounders, the excess risk of decline in LVEF over no decline for the primary outcome measure remained significant (hazard ratio: 1.98; 95% confidence interval: 1.29 to 3.06). When stratified by LVEF at index echocardiography (≥70%, 60% to 69%, and <60%), the risk of decline in LVEF on the primary outcome was consistently seen in all the subgroups, without any interaction (p = 0.77). CONCLUSIONS Patients with severe AS with >10% declines in LVEF at 1 year after diagnosis had worse AS-related clinical outcomes than those without declines in LVEF under conservative management.

Abstract
Background:
Heart failure (HF) readmission is common post–transcatheter aortic valve replacement (TAVR). Nonetheless, limited data are available regarding its predictors and clinical impact. This study evaluated the incidence, predictors, and impact of HF readmission within 1-year post-TAVR, and assessed the effects of the prescription of HF therapies at discharge on the risk of HF readmission and death.
Methods:
Patients included in the TAVR registry of a single expert center from 2009 to 2017 were analyzed. Competing-risk and Cox regressions were performed to identify predictors of HF readmission and death.
Results:
Among 750 patients, 102 (13.6%) were readmitted for HF within 1-year post-TAVR. Overall, 53 patients (7.1%) experienced late readmissions (>30 days post-TAVR), and 17 (2.3%) had multiple readmissions. In ≈30% of readmissions, no trigger could be identified. Predominant causes of readmissions were changes in medication/nonadherence and supraventricular arrhythmia. Independent predictors of HF readmission included diabetes mellitus, chronic lung disease, previous acute HF, grade III or IV aortic regurgitation, and pulmonary hypertension both at discharge from the index hospitalization but not HF therapies. Overall, HF readmission did not significantly impact all-cause mortality (hazard ratio [HR], 1.36 [95% CI, 0.99–1.85]). However, late (HR, 1.90 [95% CI, 1.30–2.78]) and multiple HF readmissions (HR, 2.10 [95% CI,1.17–3.76]) were significantly associated with all-cause mortality. Prescription of renin-angiotensin system inhibitors at discharge was associated with a lower rate of all-cause mortality, especially among patients receiving doses of 25% to <50% (HR, 0.67 [95% CI, 0.48–0.94]) and 75% to 100% (HR, 0.61 [95% CI, 0.37–0.98]) of the optimal daily dose.
Conclusions:
HF readmission is common within 1-year of TAVR. Late and multiple HF readmissions associate with an increased risk of long-term all-cause mortality. Baseline comorbidities (diabetes, chronic lung disease, previous acute HF) and echocardiographic findings at discharge (grade III or IV aortic regurgitation, pulmonary hypertension) identified patients at high risk of HF readmission.

Abstract
Introduction: In aortic stenosis (AS), there are clear sex differences in clinical presentation, left ventricular (LV) response to pressure overload, and pathophysiology of valvular calcification. These differences may affect outcome following valve intervention.Area covered: This review aims to discuss sex differences in clinical presentation, pathophysiology of aortic valve calcification, LV remodeling in view of historic and recent echocardiographic and cardiac magnetic resonance imaging studies, and outcome after valve intervention. In addition, it will also provide some brief insights on the exercise physiology in women and men with AS.Expert commentary: Women at presentation are often older, have higher prevalence of hypertension and diastolic dysfunction, while men are younger, and more often have a bicuspid aortic valve and higher atherosclerotic disease burden. Men have more valve calcification than women for a given severity of AS and develop different patterns of LV remodeling and myocardial fibrosis. Although women tend to walk shorter on treadmill and achieve lower metabolic equivalents, they achieve similar peak heart rates and blood pressure, and the frequency of revealed symptoms during exercise test is comparable in both sexes. Men are more likely to undergo a surgical AVR with better outcome, while women have generally better outcome after TAVI.
