Abstract
Due to bicuspid aortic valve aortic stenosis, a 78-year-old man with a history of esophagectomy and presternal gastric tube reconstruction required aortic valve replacement (AVR). AVR with a bioprosthetic valve was performed through a right parasternal thoracotomy. Despite the unfavorable conditions for conventional median sternotomy, AVR was successfully performed through an alternate approach. The right parasternal approach was excellent for AVR in patients with presternal gastric tube reconstruction for esophageal cancer (EC).

Usefulness of frailty assessment using the revised Japanese version of the Cardiovascular Health Study on the prediction of clinical outcomes in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement. Cardiovasc Interv Ther 2024:10.1007/s12928-024-01043-z.

Abstract
Frailty assessment is essential for deciding the treatment strategy for patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). Recently, the revised Japanese version of the Cardiovascular Health Study (J-CHS) criteria has been proposed for the frailty assessment; however, it is unclear whether the criteria are useful for the risk stratification in these patients. We investigated the impact of frailty assessment using the revised J-CHS criteria on clinical outcomes in patients with AS undergoing TAVR. We examined 205 consecutive severe AS patients who underwent TAVR at two tertiary hospitals from May 2018 to December 2022. Frailty was defined by the revised J-CHS criteria (score ≥ 3) before TAVR. The primary outcome was major adverse cardiac or cerebrovascular events (MACCE). Among the studied patients, the mean age was 84 years and 65% were female. Frailty was present in 51% of patients. During a median follow-up period of 1000 (interquartile range 677-1210) days, MACCE occurred in 22 patients. Frailty was significantly independently associated with higher risks of the MACCE adjusted for confounders related to nutritional status, severity of AS, comorbidities [hazard ratio (HR) 5.09, 95% confidence interval (CI) 1.70-15.23; HR 3.94, 95% CI 1.34-11.55; HR 3.12, 95% CI 1.14-8.53; HR 3.31, 95% CI 1.21-9.02, respectively]. Frailty determined by the revised J-CHS criteria was associated with clinical outcomes, suggesting these criteria would be useful for risk stratification in Japanese patients with AS undergoing TAVR.

Abstract
A 67-year-old woman with severe aortic stenosis (AS) was transferred to our hospital for large B-cell lymphoma treatment. Because of her high risk of anthracycline-induced cardiotoxicity due to severe AS and low performance status, the patient was initially treated with doxorubicin-free chemotherapy. However, doxorubicin was considered necessary to achieve complete remission. After multidisciplinary team discussions, transcatheter aortic valve replacement (TAVR) was performed without complications. Nine days after TAVR, the patient received the first cycle of anthracycline-containing chemotherapy (R-CHOP). Currently, 12 months after completing 4 cycles of R-CHOP, the patient remains in complete remission without having developed cardiotoxicity.

Abstract
OBJECTIVE To assess the occurrence, predictors, and outcomes of hypo-attenuated leaflet thickening (HALT) and thrombus outside the prosthetic valve following surgical aortic valve replacement. METHODS A total of 118 patients underwent surgical aortic valve replacement with bioprosthetic valves between July 2020 and June 2022. Sixty-two (52.5%) patients, which is a fairly high number of patients, underwent cardiac computed tomography and transthoracic echocardiography one week after surgery. Patients were divided into two groups, those with HALT (n = 14) and those without HALT (n = 48). RESULTS Of the 62 patients who underwent cardiac computed tomography, HALT was observed in 14 (22.5%) patients during the very early postoperative phase. Reduced leaflet motion was observed in two of the 14 patients. The low-attenuation areas were located outside the prosthetic valve in 10 cases (71.4%) in the HALT group and in 14 cases (29.2%) in the non-HALT group. More than 50% of patients (57.1%) with HALT and 79.2% without HALT were administered warfarin. Neither in-hospital deaths nor postoperative thromboembolic events were observed during hospitalization. No patient had a mean pressure gradient > 20 mmHg in either group. CONCLUSION HALT was observed in one-fifth of the cases after surgical aortic valve replacement during the very early postoperative phase in an institution wherein administration of continuous heparin infusion after surgery is a standard practice. HALT did not affect the early prognosis or incidence of cerebral infarction.

[PMID: 39215784 DOI: 10.1007/s12574-024-00659-7] [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: 05/09/2024] [Revised: 08/07/2024] [Accepted: 08/19/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND Calcification score by cardiac computed tomography (CT) is required for diagnosis of paradoxical low-flow/low-gradient (PLFLG) aortic stenosis (AS). According to the guideline, velocity ratio (VR) < 0.25 by echocardiography is defined as severe AS, but utility of VR in patients with PLFLG AS remains unknown. This retrospective study was therefore conducted to investigate the utility of VR for a diagnosis of severe AS based on CT in patients with PLFLG AS. METHODS We studied 58 patients with PLFLG AS. Severity of AS was defined as calcium score derived from cardiac CT. RESULTS Of the 58 patients, 28 (48.3%) were diagnosed with severe AS based on CT, while 23 of them (82.1%) had VR < 0.25. It was noteworthy that receiver operating characteristic curve analysis showed that the optimal VR cutoff value for a diagnosis of severe AS was 0.25, with an area under the curve of 0.870 (P < 0.001). Sensitivity, specificity, positive predictive value, and negative predictive value of VR < 0.25 for a diagnosis of severe AS were 82.1%, 86.7%, 85.2% and 83.9%, respectively. Furthermore, patients who match the value of VR and severity of AS based on CT had higher prevalence of atrial fibrillation, higher serum brain natriuretic peptide concentration, larger left ventricular end-diastolic volume, and left ventricular stroke volume index. CONCLUSION The measurement of VR is simple, and VR < 0.25 can be used for diagnosis of patients with PLFLG AS as severe. Our findings may thus have clinical implications for routine clinical practice.

Abstract
Background A deep Y descent in the jugular venous pulse (JVP) is associated with diseases such as a decrease in right ventricular (RV) preload reserve. The present study investigated the relationship between RV-pulmonary arterial (PA) coupling and a deep Y descent, examined risk factors for a deep Y descent and clarified whether a deep Y descent was an independent risk factor for cardiac events irrespective of RV-PA coupling in patients with heart failure (HF). Methods We enrolled 350 patients with HF who underwent echocardiography and JVP examination. A deep Y descent was identified by a deeper 'Y' descent than 'X' descent in the JVP waveform. We defined cardiac events of HF as follows: sudden death, death from HF, the emergent infusion of loop diuretics, or hospitalization for decompensated HF. Results and Conclusions A deep Y descent and cardiac events were observed in 129 and 83 patients, respectively. The prevalence of a deep Y descent increased with decreases in the tricuspid annular plane systolic excursion (TAPSE)/systolic pulmonary arterial pressure (SPAP) ratio. Not only the TAPSE/SPAP ratio (odds ratio,0.756 per0.1 mm/mmHg, 95 %confidence interval [CI], 0.660-0.866, p < 0.001), but also age, atrial fibrillation, and the use of beta-blockers were independent factors for a deep Y descent in multivariate logistic model. Multivariate Cox hazard model demonstrated that a deep Y descent was for cardiac events in patients with HF (Hazard ratio,2.682, 95 %CI, 1.599-4.497, p < 0.001) irrespective of the TAPSE/SPAP ratio. The development of therapeutic strategies based on central venous waveform may be needed for patients with HF.

Abstract
BACKGROUND The presence of insomnia exhibits a profound association with diverse cardiovascular pathologies. However, its prognostic implications in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis remain ambiguous. METHODS This retrospective study enrolled patients who underwent TAVR for severe aortic stenosis at a prominent academic center from 2015 to 2022. The impact of insomnia, operationally defined as the prescription of soporific agents, on the two-year composite primary outcome comprising all-cause mortality and hospital readmissions was scrutinized. RESULTS A cohort of 345 patients (median age 85 years, 99 males) was encompassed in the analysis. All subjects underwent successful TAVR and subsequent discharge. The presence of insomnia (N = 91) emerged as an independent predictor of the two-year composite endpoint, with an adjusted hazard ratio of 1.66 (95 % confidence interval 1.08-2.57, p = 0.022), significantly delineating the two-year cumulative incidence of the primary endpoint (40 % versus 30 %, p = 0.035). CONCLUSION Approximately one-fourth of TAVR candidates manifested symptoms of insomnia, a condition autonomously correlated with heightened mortality and morbidity following the TAVR procedure. The optimal strategy for addressing insomnia in TAVR candidates constitutes a paramount consideration for future interventions.

Abstract
BACKGROUND Current guidelines recommend direct oral anticoagulants (DOACs) and warfarin for patients with atrial fibrillation (AF) who have a bioprosthetic valve (BPV). However, the data related to elderly patients (aged ≥80 years) with BPV replacement and AF are limited. METHODS This post-hoc subgroup analysis of a BPV-AF Registry enrolled 752 patients with BPV replacement and AF. The primary net outcome was a composite of cardiac death, stroke, systemic embolism, major bleeding, and cardiovascular events. RESULTS Among 752 patients, 429 (57%) patients were ≥ 80 and 323 (43%) were < 80 years old. The higher risk in patients aged ≥80 than <80 years was significant for the net outcome (hazard ratio [HR], 2.04; 95% confidence interval [CI], 1.31-3.17; P = 0.001). After adjustment for confounders, there was no statistically significant difference between warfarin (reference) and DOAC users in the risk of net outcomes (adjusted HR, 1.26; 95% CI, 0.71-2.24; P = 0.44), stroke and systemic embolism (adjusted HR, 2.01; 95% CI, 0.48-8.38; P = 0.34), and major bleeding (adjusted HR, 0.73; 95% CI, 0.11-4.98; P = 0.75) in patients aged ≥80 years old as well as those aged <80 years. Among 489 warfarin users, the cumulative incidence of net outcomes tended to be higher in patients aged ≥80 than <80 years (12.2% vs. 5.7% at 1 year, log-rank P = 0.002). Among 263 DOAC users, however, it was similar between patients aged ≥80 and < 80 years. CONCLUSIONS The present study demonstrated that DOAC showed similar efficacy and safety compared with warfarin even in elderly patients aged ≥80 years with BPV replacement and AF.

Cerebrovascular Disease Detected on Preprocedural Computed Tomography in Patients With Severe Aortic Stenosis Undergoing Aortic Valve Replacement. J Am Heart Assoc 2024; 13:e035078. [PMID: 38979790 PMCID: PMC11292776 DOI: 10.1161/jaha.124.035078] [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: 02/19/2024] [Accepted: 05/16/2024] [Indexed: 07/10/2024]
Abstract
BACKGROUND There is a scarcity of data on the prevalence and clinical impact of cerebrovascular disease detected on preprocedural computed tomography (CT) before aortic valve replacement (AVR) in patients with severe aortic stenosis. METHODS AND RESULTS Among patients with severe aortic stenosis undergoing AVR, the authors compared clinical outcomes between patients with and without cerebrovascular disease detected on preprocedural CT, which was defined as chronic brain infarction or hemorrhage. The primary outcome measure in this study was a composite of all-cause death or stroke. Among 567 study patients, 200 patients (35.3%) had cerebrovascular disease on preprocedural CT. Among 200 patients with cerebrovascular disease on preprocedural CT, only 28.5% of patients had a clinical history of symptomatic stroke. The cumulative 3-year incidence of death or stroke was higher in patients with cerebrovascular disease on preprocedural CT than in those without cerebrovascular disease on preprocedural CT (40.7% versus 24.1%, log-rank P<0.001). After adjusting for confounders, the higher risk of patients with cerebrovascular disease on preprocedural CT relative to those without remained significant for death or stroke (hazard ratio [HR], 1.42 [95% CI, 1.02-1.98]; P=0.04). Among 200 patients with cerebrovascular disease on preprocedural CT, patients with prior symptomatic stroke compared with those without were not associated with higher adjusted risk for death or stroke (HR, 1.18 [95% CI, 0.72-1.94]; P=0.52). CONCLUSIONS Among patients with severe aortic stenosis undergoing AVR, a substantial proportion had cerebrovascular disease on preprocedural CT, with a clinical history of symptomatic stroke in one-fourth of patients. Regardless of history of symptomatic stroke, patients with cerebrovascular disease on preprocedural CT had worse clinical outcomes compared with those without cerebrovascular disease on preprocedural CT.

Heart Vessels 2024:10.1007/s00380-024-02437-y. [PMID: 39008083 DOI: 10.1007/s00380-024-02437-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Accepted: 06/30/2024] [Indexed: 07/16/2024]
Abstract
Transcatheter aortic valve replacement (TAVR) offers a solution, especially for high-risk aortic stenosis (AS) patients. However, patient outcomes post-TAVR show variability, highlighting the need for reliable prognostic indicators. Brachial-ankle pulse wave velocity (baPWV), a measure of arterial stiffness, may predict outcomes post-TAVR. This study aims to explore baPWV's prognostic value in relation to all-cause mortality post-TAVR. This study prospectively enrolled 212 severe AS patients undergoing TAVR between September 2015 and December 2021, focusing on pre- and post-TAVR baPWV measurements to explore associations with all-cause mortality. Of the 212 patients (119 females, 93 males, mean age 85 years), post-TAVR baPWV increased significantly from 1589 ± 376 to 2010 ± 521 cm/s (p < 0.001). Aortic valve (AV) peak velocity and mean pressure gradient decreased, while AV area increased, indicating procedural success. Despite this, 88% of patients experienced an increase in baPWV, with higher pre-procedure AV peak velocity and mean pressure gradient identified as predictors of increased baPWV post-TAVR. Over 23 months, 29 patients (14%) reached the primary endpoint of all-cause mortality. Notably, changes in baPWV, rather than baseline values, were significantly associated with event-free survival (HR: 0.64 per 1SD increase, p = 0.009). The study highlights the prognostic value of baPWV changes post-TAVR in predicting patient outcomes. Elevated baPWV post-TAVR may reflect a beneficial adaptation to altered hemodynamics, suggesting the need for individualized patient evaluation and the integration of baPWV measurements into clinical practice for improved post-TAVR management.

Abstract
BACKGROUND Perioperative management of patients on dialysis is critical for controlling bleeding and thrombotic risk, in addition to infection control. Postoperative anticoagulation is often difficult to control, and different institutions have different policies. Therefore, in this study, we aimed to investigate factors associated with postoperative bleeding events and whether warfarin (WF) therapy affects the incidence of postoperative bleeding events, total mortality, and stroke. METHODS Patients who were admitted to the cardiovascular surgery department and underwent valve replacement or plasty were included, and those who underwent mechanical valve introduction were excluded. Thirty-nine patients were included in the study. The primary endpoint was to identify factors associated with the composite endpoint of postoperative bleeding events, and the secondary endpoint was to determine the effect size of WF therapy on postoperative bleeding events, all-cause mortality, and stroke and the strength of association between the crossed endpoints. The strength of the association between the crossed items was examined. RESULTS Low body weight (p = 0.038) was identified as a factor associated with the primary endpoint of postoperative bleeding events. The secondary endpoint of whether or not patients received WF therapy was largely unrelated to bleeding events, all-cause mortality, and postoperative stroke up to 90 days after surgery. CONCLUSIONS Preliminary studies suggest that low body weight is a risk factor for postoperative bleeding events in patients on dialysis, although further exploration of other factors will be necessary with the accumulation of similar cases.

Abstract
AIM Although current guidelines recommend concomitant tricuspid annuloplasty for moderate or greater tricuspid regurgitation (TR) and/or dilated annulus, there remains significant variation in undertaking concomitant tricuspid valve surgery (TVA) across different centres. This meta-analysis aimed to compare the clinical outcomes of concomitant tricuspid valve surgery for patients with moderate or greater TR and/or dilated annulus at the time of mitral valve (MV) surgery. METHOD A systematic review of the literature using six databases. Eligible studies include comparative studies on TVA concomitant with MV surgery versus MV surgery alone. A meta-analysis was performed on studies reporting outcomes of interest to quantify the effects of concomitant tricuspid ring annuloplasty. RESULTS Two randomised controlled trials and six cohort studies were included in the analysis. 1,941 patients were included in the analysis, of whom, 1,090 underwent concomitant TVA and 851 underwent MV surgery alone. Pooled analysis demonstrated that there was less progression of moderate/severe TR in the concomitant group (3.0% vs 9.6%; odds ratio [OR] 0.29; 95% confidence interval [CI] 0.13-0.55; p=0.0001). There was no significant difference in in-hospital mortality (3.0% vs 3.8%; OR 0.79; 95% CI 0.47-1.34; p=0.38). The rate of permanent pacemaker implantation was higher in the concomitant group although this did not reach statistical significance (7.6% vs 5.3%; OR 1.30; 95% CI 0.85-1.98; p=0.23). Cardiopulmonary bypass was longer in the concomitant TVA group by 20 minutes (mean difference 13.9-26.0; p<0.00001). CONCLUSIONS Our study demonstrated that concomitant tricuspid ring annuloplasty at the time of MV surgery is associated with a significantly lower rate of TR progression without increasing the operative mortality. There is a trend towards a higher permanent pacemaker implantation rate although this did not reach statistical significance.

Abstract
Despite advances in multidisciplinary acute care for myocardial infarction (MI), the clinical need to manage heart failure and elevated mortality risks in the remote phase of MI remains unmet. Various prognostic models have been established using clinical indicators obtained during the acute phase of MI; however, most of these indicators also show chronic changes in the post-MI phase. Although relevant guidelines recommend follow-up assessments of some clinical indicators in the chronic phase, systematic reassessment has not yet been fully established and implemented in a real-world clinical setting. Therefore, clinical evidence of the impact of such chronic transitions on the post-MI prognosis is lacking. We speculate that post-MI reassessment of key clinical indicators and the impact of their chronic transition patterns on long-term prognoses can improve the quality of post-MI risk stratification and help identify residual risk factors. Several recent studies have investigated the impact of the chronic transition of some clinical indicators, such as serum albumin level, mitral regurgitation, and left-ventricular dysfunction, on post-MI prognosis. Interestingly, even in MI survivors with these indicators within their respective normal ranges in the acute phase of MI, chronic transition to an abnormal range was associated with worsening cardiovascular outcomes. On the basis of these recent insights, we discuss the clinical significance of post-MI reassessment to identify the trajectories of several clinical indicators and elucidate the potential residual risk factors affecting adverse outcomes in MI survivors.

Abstract
BACKGROUND This study investigated the long-term outcomes of physiological and anatomical repair for corrected transposition of the great arteries and double-outlet right ventricle with discordant atrioventricular connection. METHODS This single-center retrospective study included 146 patients who underwent biventricular repair of corrected transposition of the great arteries or double-outlet right ventricle with discordant atrioventricular connections from 1972 to 2023. Survival rate, freedom from reoperation, New York Heart Association (NYHA) Functional Classification, and incidence of systemic ventricular dysfunction in the long-term were compared between physiological repair (PR) and anatomical repair (AR) groups. RESULTS The PR group consisted of 55 patients, with median age at repair of 10.3 years. Thirty-one patients underwent conventional Rastelli procedure, and 24 patients underwent atrial and/or ventricular septal defect closure. The AR group consisted of 91 patients, with median age at repair of 5.8 years. Seventy-two patients underwent atrial switch plus Rastelli procedure and 19 patients underwent atrial plus arterial switch operation. The 30-year survival was 63.5% in the PR group and 72.3% in the AR group (P = .448). The 30-year freedom from reoperation was 71.9% in the PR group and 62.2% in the AR group (P = .220). There was a significant difference in the incidence of systemic ventricular dysfunction between the groups (87.5% in the PR group and 35.3% in the AR group, P < .001) and in the NYHA classification of long-term survivors (mean NYHA class of 1.9 in the PR group and 1.5 in the AR group, P = .009). CONCLUSIONS The systemic ventricular function and general status in the long-term were significantly better in AR patients, suggesting the potential advantage of AR.

Abstract
BACKGROUND AND PURPOSE Anticoagulant therapy with vitamin K antagonists is recommended within 3 to 6 months after bioprosthetic valve replacement to prevent thromboembolic events. However, data regarding whether direct oral anticoagulants can be an alternative to warfarin in such patients are limited. The purpose of this study is to compare the efficacy and safety of edoxaban versus warfarin within 3 months after bioprosthetic valve replacement. METHODS The ENBALV trial is an investigator-initiated, phase 3, randomized, open-label, multicenter study. It involves patients aged 18 to 85 years undergoing bioprosthetic valve replacement at the aortic and/or mitral position. They are randomized 1:1 to receive either edoxaban or warfarin. Administration of edoxaban or warfarin is to be continued for 12 weeks after surgery. The primary outcome is the occurrence rate of stroke or systemic embolism at 12 weeks after surgery. The net clinical outcome is a composite of stroke, systemic embolism, or major bleeding, which is included in the secondary outcomes. CONCLUSION The ENBALV trial demonstrates the efficacy and safety of edoxaban compared with warfarin in patients early after bioprosthetic valve replacement, including patients with sinus rhythm, which will bring a significant benefit to patients in clinical practice.

Association of computed tomography-derived muscle mass and quality with delayed acquisition independent walking after cardiovascular surgery. J Cachexia Sarcopenia Muscle 2024. [PMID: 38898544 DOI: 10.1002/jcsm.13521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 03/21/2024] [Accepted: 04/29/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND In the context of cardiovascular surgery, the foremost concern lies in delayed functional recovery, as typified by the acquisition of independent walking after surgery, among older patients with decline in skeletal muscle mass and quality. Computed tomography (CT), which is typically employed for the preoperative assessment of pathological conditions in patients undergoing cardiovascular surgery, is also suitable for screening for potential decline in skeletal muscle mass and quality. The aim of this study was to examine the predictive capabilities of CT-derived parameters such as muscle mass and muscle quality for the delayed acquisition of independent walking in the postoperative period. METHODS This retrospective study enrolled consecutive Japanese patients who underwent elective cardiovascular surgery between May 2020 and January 2023. In total, 139 patients were included in the analyses. Based on the preoperative CT image, the psoas muscle volume index (PMVI) and psoas muscle attenuation (PMA) were calculated. Information on patient characteristics, including preoperative physical fitness such as handgrip strength/body mass index (GS/BMI), short physical performance battery (SPPB), and 6-min walking distance (6MWD), were obtained from the medical records. We defined delayed acquisition of independent walking after surgery as the inability to walk 100 m within 4 days after surgery. RESULTS The median age of the patients was 72 (interquartile: 64-78) years, and 74.8% (104/139) were men; 47.5% corresponded to the delayed group. The areas under the curves of SPPB, GS/BMI, 6MWD, PMVI, and PMA against delayed acquisition of independent walking after surgery were 0.68 [95% confidence interval (CI): 0.59 to 0.77], 0.72 (95% CI: 0.63 to 0.80), 0.73 (95% CI: 0.65 to 0.82), 0.69 (95% CI: 0.60 to 0.78), and 0.78 (95% CI: 0.70 to 0.85), respectively. In the multivariate logistic regression analysis, low PMA was significantly associated with delayed acquisition of independent walking even after adjustment for patient characteristics including physical fitness [model 1: SPPB (OR, 1.14; 95% CI: 1.03-1.25), model 2: GS/BMI (OR, 1.13; 95% CI: 1.03-1.25), and model 3: 6MWD (OR, 1.14; 95% CI: 1.03-1.25)], but PMVI was not. CONCLUSIONS Our study revealed a strong association between PMA, a marker of CT-derived muscle quality, and the postoperative delay in achieving independent walking in patients who underwent cardiovascular surgery. The technique to obtain information on muscle quality during the time period before surgery may be an option for timely therapeutic intervention in patients who may have delayed acquisition of independent walking after surgery.

Abstract
Basic mechanism of ventricular functional mitral regurgitation (FMR) is subvalvular tethering. Left ventricular (LV) dilatation, in association with mitral valve (MV) annular dilatation, causes outward displacement of papillary muscles (PMs), which abnormally pulls or tethers MV leaflets, resulting in MV tenting, reduction in leaflets coaptation and MR. Because surgical annuloplasty does shorten distance between anterior and posterior MV annuli to improve coaptation but does not address this subvalvular tethering, ventricular FMR frequently persists or recurs in the chronic stage after surgical annuloplasty. This high incidence of persistent/recurrent MR requires additional procedures to reduce subvalvular tethering. Although patients occasionally show marked improvements after annuloplasty with surgical tethering reduction procedures such as PM approximation, evidence to support benefits of such surgery is limited, requiring further trials. Recently, MV adaptation or MV leaflets tissue growth associated with LV dilatation attracts attention. Patients with larger MV leaflets with significant LV dilatation/dysfunction show less MV tethering and MR compared to those with smaller MV leaflets but with similar LV remodeling, suggesting the protective or beneficial role of MV leaflets tissue growth against LV remodeling. The MV leaflets tissue growth has the potential to lead to novel strategies of treatment for ventricular FMR. It is well known that atrial FMR is frequent in patients with left atrial dilatation, typically in those with isolated atrial fibrillation. The degree of atrial FMR is usually mild, even when it is present, and occasionally moderate, and severe atrial FMR is really rare. It is known that only severe regurgitation causes heart failure in primary MR, resulting in description on indications of surgery or intervention for only severe MR in current guidelines. Therefore, this atrial FMR up to moderate degree did not attract attention for a long time. However, recent studies have shown that patients with only moderate atrial FMR develop severe heart failure, suggesting more aggressive indication of MV surgery or intervention for "moderate" regurgitation in patients with atrial FMR. Therefore, atrial FMR is now recognized highly important. The unveiled malignant nature of atrial FMR arises many questions, including (1) why patients with only moderate atrial FMR develop heart failure? (2) do patients with mild atrial FMR develop heart failure or not?, and many others. Atrial FMR seems even more mysterious after the unveiling of its significance.

Abstract
Background: The prognostic significance of different presentations of aortic stenosis (AS) remains unclear. Our aim was to analyze outcomes after transcatheter aortic valve replacement (TAVR) according to preoperative AS symptoms. Methods and Results: We retrospectively enrolled 369 consecutive patients (age 84.3±5.0 years, and 64% females) who underwent TAVR from 2014 to 2021. We divided them into 4 groups by the main preoperative symptom: asymptomatic (n=50), chest pain (n=46), heart failure (HF; n=240), and syncope (n=33). Post-TAVR rates of HF readmission, all-cause death and cardiac death were compared among the 4 groups. The 4 groups showed no significant trends in age, sex, stroke volume index, or echocardiography indices of AS severity. During a follow-up, the overall survival rate at 1 and 5 years after TAVR was 97% and 90% in the asymptomatic group, 96% and 69% in the chest pain group, 93% and 69% in the HF group, and 90% and 72% in the syncope group, respectively. HF and syncope symptom had significantly lower HF readmission or cardiac death-free survival at 5 years after TAVR (log-rank test P=0.038). In the Cox hazard multivariate analysis, preoperative syncope was an independent predictor of future HF readmission or cardiac death after TAVR (HR=9.87; 95% CI 1.67-97.2; P=0.035). Conclusions: AS patients with preoperative syncope or HF had worse outcomes after TAVR than those with angina or no symptoms.

Abstract
The indication for surgery for tricuspid regurgitation (TR) has reached a major turning point. It has become clear that the presence of moderate or severe TR alone worsens the prognosis of life, and the previous guidelines of Japanese Circulation Society, in which the indication for surgery was recommended at the timing of "right heart failure difficult to treat medically," now recommends surgery with a trigger of "repeated right heart failure" in the 2020 edition. In addition, a new repair technique targeting at subvalvular structure has been developed for end-stage TR to overcome a high TR recurrence rate that is associated with severe right ventricular enlargement and leaflet tethering. This review focuses on the spiral suspension technique, in which the papillary muscles are spirally suspended towards the septal leaflet annulus to correct tethering and enhances the understanding of its application in the context of TR management.

Abstract
Coronary artery disease (CAD) is a common condition caused by the accumulation of atherosclerotic plaques. It can be classified into stable CAD or acute coronary syndrome. Coronary computed tomography angiography (CCTA) has a high negative predictive value and is used as the first examination for diagnosing stable CAD, particularly in patients at intermediate-to-high risk. CCTA is also adopted for diagnosing acute coronary syndrome, particularly in patients at low-to-intermediate risk. Myocardial ischemia does not always co-exist with coronary artery stenosis, and the positive predictive value of CCTA for myocardial ischemia is limited. However, CCTA has overcome this limitation with recent technological advancements such as CT perfusion and CT-fractional flow reserve. In addition, CCTA can be used to assess coronary artery plaques. Thus, the indications for CCTA have expanded, leading to an increased demand for radiologists. The CAD reporting and data system (CAD-RADS) 2.0 was recently proposed for standardizing CCTA reporting. This RADS evaluates and categorizes patients based on coronary artery stenosis and the overall amount of coronary artery plaque and links this to patient management. In this review, we aimed to review the major trials and guidelines for CCTA to understand its clinical role. Furthermore, we aimed to introduce the CAD-RADS 2.0 including the assessment of coronary artery stenosis, plaque, and other key findings, and highlight the steps for CCTA reporting. Finally, we aimed to present recent research trends including the perivascular fat attenuation index, artificial intelligence, and the advancements in CT technology.

Abstract
Purpose Postoperative infections pose an important problem for patients with cardiac disease. Moreover, oral health status is associated with the risk of longer hospital stays. Therefore, the oral health status of patients was assessed before open-heart surgery. This study aimed to determine the relationship between oral health status and postoperative status. Methods The study included 25 patients who underwent open-heart surgery at our university hospital in 2020. Upon admission, dentists conducted an oral examination and assessed the oral health status of the patients, also using the Japanese version of the Oral Health Assessment Tool (OHAT-J), Revised Oral Assessment Guide (ROAG), oral moisture level, oral bacteria, and other relevant factors. The study investigated the association with postoperative status. Findings Significant postoperative infections were found in patients aged ≥70 years, with an OHAT-J score of ≥5, OHAT-J lip score of ≥1, Streptococcus γ count of 1.0 × 10^6 or higher (CFU/mL), and increased Streptococcus γ before and after surgery. The duration of hospitalization correlated with the OHAT-J, OHAT-J gum and tissue, and ROAG scores. The duration of intensive care unit (ICU) stays correlated with the OHAT-J score. Conclusions The study demonstrates that OHAT-J scores are linked with predicting not just postoperative infection but also the length of hospitalization and ICU stay. As OHAT-J scores do not necessitate specialized dental instruments, they are straightforward and beneficial for healthcare professionals outside of dentistry.

Abstract
Chronic aortic regurgitation (AR) leads to volume overload in the left ventricle (LV), which is well tolerated for years. In this condition, the LV usually dilates with minimal reduction in the ejection fraction (EF), even in the absence of symptoms. Echocardiography is the primary imaging test used to quantify AR. However, no single assessment of Doppler measures is accurate and precise in individual patients; therefore, the integration of multiple parameters is necessary. Recent guidelines recommend surgical treatment for severe AR in patients who are symptomatic or have an LVEF < 55% and an end-systolic diameter > 50 mm. Nevertheless, advances in imaging technology have improved the quantification of AR and the assessment of LV subclinical dysfunction. It is widely recognized that patients who undergo aortic valve replacement/repair (AVR) due to symptoms or a low LVEF experience worse outcomes than those undergoing AVR for non-Class I indications. In fact, subclinical irreversible myocardial damage may occur in clinically well-compensated and closely monitored patients while awaiting formal surgical indications. This condition could be prevented by the use of multimodal imaging parameters, in particular longitudinal LV strain and magnetic resonance imaging. In addition, better cut-off values for mortality predictors should be established. This review aims to identify simple models that integrate several echocardiographic and cardiac magnetic resonance-derived parameters to predict the optimal timing of surgical treatment in asymptomatic patients with chronic severe AR.

Abstract
BACKGROUND There is a scarcity of data on the prevalence of abnormal findings on preprocedural computed tomography (CT) before aortic valve replacement (AVR) in patients with aortic stenosis (AS). METHODS Among consecutive 593 patients with severe AS who were planned to undergo AVR, we evaluated the prevalence of clinically significant incidental noncardiac findings on preprocedural CT. Clinically significant incidental noncardiac findings were defined as newly detected abnormalities that required therapy, consultation for expert, further investigation, or clinical follow-up. RESULTS The mean age was 82.0 years and 39.5 % of the patients were men. Of those, 78.4 % of the patients were treated with transcatheter aortic valve implantation (TAVI) and 21.6 % of the patients were treated with surgical AVR (SAVR). There were 271 clinically significant incidental noncardiac findings in 227 patients (38.3 %) including 2.5 % of malignancy. The prevalence of clinically significant incidental noncardiac findings were higher in the TAVI group than in the SAVR group (40.2 % versus 31.3 %). The prevalence of clinically significant incidental noncardiac findings were lower in patients under 60 years of age (10.0 %) than in patients over 60 years of age (60-69 years: 40.0 %, 70-79 years: 34.3 %, 80-89 years: 39.7 %, and ≥90 years: 42.1 %). CONCLUSIONS Clinically significant incidental noncardiac findings were newly identified on preprocedural CT in approximately 40 % of patients with severe AS undergoing AVR including 2.5 % of malignancy.

Abstract
The Canadian Association of Radiologists (CAR) Cardiovascular Expert Panel is made up of physicians from the disciplines of radiology, cardiology, and emergency medicine, a patient advisor, and an epidemiologist/guideline methodologist. After developing a list of 30 clinical/diagnostic scenarios, a rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for one or more of these clinical/diagnostic scenarios. Recommendations from 48 guidelines and contextualization criteria in the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) for guidelines framework were used to develop 125 recommendation statements across the 30 scenarios (27 unique scenarios as 2 scenarios point to the CAR Thoracic Diagnostic Imaging Referral Guideline and the acute pericarditis subscenario is included under 2 main scenarios). This guideline presents the methods of development and the referral recommendations for acute chest pain syndromes, chronic chest pain, cardiovascular screening and risk stratification, pericardial syndromes, intracardiac/pericardial mass, suspected valvular disease cardiomyopathy, aorta, venous thrombosis, and peripheral vascular disease.

Abstract
BACKGROUND Based on the results of a clinical trial in Japan, transcatheter aortic valve replacement (TAVR) for hemodialysis (HD) patients gained approval; however, mid-term TAVR outcomes and transcatheter aortic valve (TAV) durability in HD patients remain unexplored.Methods and Results: We analyzed background, procedural, in-hospital outcome, and follow-up data for 101 HD patients and 494 non-HD patients who underwent TAVR using balloon-expandable valves (SAPIEN XT or SAPIEN 3) retrieved from Osaka University Hospital TAVR database. Periprocedural mortality and TAVR-related complications were comparable between HD and non-HD patients. However, Kaplan-Meier analysis revealed that HD patients had significantly lower survival rates (log-rank test, P<0.001). In addition, HD patients had significantly higher rates of severe structural valve deterioration (SVD) than non-HD patients (Gray test, P=0.038). CONCLUSIONS TAVR in HD patients had comparable periprocedural mortality but inferior mid-term survival and TAV durability than in non-HD patients. Indications for TAVR in younger HD patients should be carefully determined, considering the possibility of a TAV-in-TAV procedure when early SVD occurs.

Abstract
OBJECTIVE Reports on long-term outcomes of surgical aortic valve replacement (AVR) for patients aged < 60 years are scarce in Japan. Hence, we aimed to evaluate these outcomes in patients aged < 60 years. METHODS Between March 2000 and December 2020, 1477 patients underwent aortic valve replacement. In total, 170 patients aged < 60 years who underwent aortic valve replacement were recruited. Patients aged < 18 years were excluded. Patient data collected from the operative records and follow-up assessments were reviewed. RESULTS The mean age was 49 ± 9 years, and 64.1% of patients were male. One-hundred-and-fifty-two patients (89.4%) underwent aortic valve replacement with a mechanical valve and 18 (10.6%) with a bioprosthetic valve. The mean follow-up period was 8.1 ± 5.5 years. No operative mortality occurred, and in-hospital mortality occurred in one patient (0.6%). Ten late deaths occurred, with seven cardiac-related deaths. The overall survival rate was 95.4 ± 1.7%, 93.9 ± 2.3%, 90.6 ± 3.9%, and 73.2 ± 11.8% at 5, 10, 15, and 20 years, respectively. Freedom from major bleeding was 96.4 ± 1.6% at 5, 10, and 15 years, and 89.0 ± 7.3% at 20 years. Freedom from thromboembolic events was 98.7 ± 1.3%, 97.3 ± 1.9%, 90.5 ± 4.5%, and 79.0 ± 11.3% at 5, 10, 15, and 20 years, respectively. Freedom from valve-related reoperation was 99.4 ± 0.6% at 5 years, 97.8 ± 1.7% at 10 and 15 years, and 63.9 ± 14.5% at 20 years. CONCLUSIONS Patients aged < 60 years undergoing aortic valve replacement with a high mechanical valve implantation rate had favorable long-term outcomes.

Abstract
OBJECTIVE Aortic dilatation concurrent with aortic valve disease is a common condition. However, the incidence of aortic dissection after aortic valve replacement for tricuspid aortic valve has not been fully investigated. Therefore, we performed a risk factor analysis for the incidence of aortic dissection after aortic valve replacement in patients with tricuspid aortic valve. METHODS We retrospectively reviewed 599 patients who underwent aortic valve replacement at our hospital between January 2000 and December 2020. We performed a risk factor analysis for the incidence of aortic dissection after aortic valve replacement in patients with tricuspid aortic valve. RESULTS Seven patients developed late aortic dissections during the follow-up period. All patients with aortic dissection underwent aortic valve replacement for aortic regurgitation. Multivariable analysis revealed that aortic regurgitation was an independent predictor of aortic dissection (p < 0.0001). The mean ascending aortic diameter at aortic valve replacement for aortic regurgitation was significantly greater in patients with aortic dissection than in those without aortic dissection (46 [43.5-46] mm vs. 39 [36-42] mm, p < 0.001). The predictive cutoff value of ascending aortic diameter was indicated using receiver operating characteristic curve analysis; 46.0 mm (area under the curve: 0.8987). Freedom rates from aortic dissection in patients with aortic regurgitation and an ascending aortic diameter ≥ 46 mm were significantly lower than those in patients with an ascending aortic diameter < 46 mm (66.7% vs. 100% at 5 years, p < 0.0001). CONCLUSION Aortic regurgitation combined with ascending aortic dilatation at aortic valve replacement could be a significant risk factor for late aortic dissection.

Abstract
BACKGROUND We determined the left ventricular end-systolic diameter (LVDs) cut-off value for risk of major adverse cardiac and cerebrovascular events (MACCE) in Japanese asymptomatic or mildly symptomatic patients undergoing aortic valve replacement (AVR) for aortic valve regurgitation (AR), and investigated the effect of left ventricular dilation on long-term postoperative outcomes.Methods and Results: The 168 patients who underwent surgical AVR for AR at Shiga University of Medical Science between January 2002 and December 2022 were included in this study. Receiver operating characteristic curve analysis showed that the cut-off value of preoperative LVDs for the incidence of MACCE was 42.8 mm (area under the curve 0.616). Postoperative outcomes were compared between patients with preoperative LVDs >42.8 mm (n=77) and those with preoperative LVDs ≤42.8 mm (n=91) using propensity score matching. The 10-year estimated rates of freedom from MACCE in those with LVDs >42.8 and ≤42.8 mm were 59.9% and 85.7%, respectively; the curves differed significantly (P=0.004). In multivariable Cox proportional hazard regression analyses, preoperative LVDs >42.8 mm was an independent predictor of MACCE (hazard ratio 2.485; 95% confidence interval 1.239-4.984; P=0.010). CONCLUSIONS Preoperative LVDs >42.8 mm is associated with an increased risk of MACCE in Japanese patients undergoing AVR for AR.

Abstract
BACKGROUND There are few reports on transthoracic echocardiography (TTE) for the evaluation of valvular heart disease in a specific area or region. METHODS AND RESULTS This cross-sectional questionnaire-based survey was conducted in 2023 in Kumamoto Prefecture, where 106 hospitals provide cardiology services. Ninety-three (88%) of the hospitals completed questionnaires regarding TTE. The severity of low flow/low gradient AS was evaluated by dobutamine stress echocardiography in only 7% of hospitals and exercise stress echocardiography for asymptomatic mitral regurgitation in only 5%. Multivariate logistic regression analysis revealed that participation in remote multi-institutional echocardiographic meetings and use of the Kumamoto Prefecture echocardiographic manual were significantly associated with the use of a multi-window approach (P < 0.05). CONCLUSIONS In Kumamoto Prefecture, echocardiographic measurements are performed according to the recommendations at a relatively low rate. Dissemination of recommendations through remote meetings and the use of the echocardiographic manual may increase the likelihood of TTE being performed according to the recommendations.

Abstract
In the aging global society, heart failure and valvular heart diseases, including aortic stenosis, are affecting millions of people and healthcare systems worldwide. Although the number of effective treatment options has increased in recent years, the lack of effective screening methods is provoking continued high mortality and rehospitalization rates. Appropriately, auscultation has been the primary option for screening such patients, however, challenges arise due to the variability in auscultation skills, the objectivity of the clinical method, and the presence of sounds inaudible to the human ear. To address challenges associated with the current approach towards auscultation, the hardware of Super StethoScope was developed. This paper is composed of (1) a background literature review of bioacoustic research regarding heart disease detection, (2) an introduction of our approach to heart sound research and development of Super StethoScope, (3) a discussion of the application of remote auscultation to telemedicine, and (4) results of a market needs survey on traditional and remote auscultation. Heart sounds and murmurs, if collected properly, have been shown to closely represent heart disease characteristics. Correspondingly, the main characteristics of Super StethoScope include: (1) simultaneous collection of electrocardiographic and heart sound for the detection of heart rate variability, (2) optimized signal-to-noise ratio in the audible frequency bands, and (3) acquisition of heart sounds including the inaudible frequency ranges. Due to the ability to visualize the data, the device is able to provide quantitative results without disturbance by sound quality alterations during remote auscultations. An online survey of 3648 doctors confirmed that auscultation is the common examination method used in today's clinical practice and revealed that artificial intelligence-based heart sound analysis systems are expected to be integrated into clinicians' practices. Super StethoScope would open new horizons for heart sound research and telemedicine.

Abstract
The objective of this network meta-analysis was to assess the efficacy and safety of apixaban, dabigatran, rivaroxaban, and edoxaban in patients diagnosed with atrial fibrillation and valvular heart disease. A comprehensive search was conducted across various electronic databases, including PubMed, Embase, and Web of Science, from inception to February 15, 2024. The search strategy utilized a combination of medical subject headings (MeSH) terms and relevant keywords related to valvular heart disease, atrial fibrillation, anticoagulant therapy, and study design, such as randomized controlled trials and observational studies. The outcomes evaluated in this analysis comprised the incidence of stroke or systemic embolism (SE), as well as the occurrences of major bleeding events. A total of 10 studies were incorporated into this meta-analysis, encompassing 40,662 participants. Of these, 12,385 received apixaban, 2,829 received dabigatran, 13,662 received rivaroxaban, 2,582 received edoxaban, and 9,202 received warfarin. The duration of follow-up in the included studies ranged from 3 to 54 months. Among the four direct oral anticoagulants (DOACs) studied, apixaban demonstrated a significant reduction in the risk of stroke or SE when compared to other DOACs and warfarin, highlighting its efficacy in patients with atrial fibrillation and valvular heart disease. Additionally, apixaban exhibited a lower risk of major bleeding events, further emphasizing its favorable safety profile compared to the other agents assessed. In conclusion, our findings suggest that apixaban may be more effective and safer than other DOACs and warfarin in this patient population. However, additional studies are warranted to compare the various DOACs in this cohort to identify the optimal treatment strategy for preventing adverse outcomes.

Abstract
The initial means of detecting right ventricular (RV) dilatation is often transthoracic echocardiography (TTE), and once the presence of RV dilatation is suspected, there is the possibility of RV volume overload, RV pressure overload, RV myocardial disease, and even nonpathological RV dilatation. With respect to congenital heart disease with RV volume overload, defects or valvular abnormalities can be easily detected with TTE, with the exception of some diseases. Volumetric assessment using three-dimensional echocardiography may be useful in determining the intervention timing in these diseases. When the disease progresses in patients with pulmonary hypertension as a result of RV pressure overload, RV dilatation becomes more prominent than hypertrophy, and RV functional parameters predict the prognosis at this stage of maladaptive remodeling. The differential diagnosis of cardiomyopathy or comparison with nonpathological RV dilatation may be difficult in the setting of RV myocardial disease. The characteristics of RV functional parameters such as two-dimensional speckle tracking may help differentiate RV cardiomyopathy from other conditions. We review the diseases presenting with RV dilatation, their characteristics, and echocardiographic findings and parameters that are significant in assessing their status or intervention timing.

Comparison of the effect of surgical versus transcatheter aortic valve replacement on the development of postoperative acute kidney injury. Heart Vessels 2024; 39:359-364. [PMID: 37978052 DOI: 10.1007/s00380-023-02334-w] [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: 06/16/2023] [Accepted: 10/26/2023] [Indexed: 11/19/2023]
Abstract
Acute kidney injury (AKI) frequently occurs after cardiac surgery. Recently, transcatheter aortic valve implantation (TAVI), a less invasive option for aortic stenosis (AS), has been increasingly performed, particularly in elderly patients. We retrospectively investigated and compared the incidence and risk factors of postoperative AKI in patients who underwent surgical aortic valve replacement (SAVR) and TAVI. This was a retrospective single-center study. Seven days postoperatively, data were obtained from medical records. Patients were classified into SAVR and TAVI groups based on age, according to the policy of the Japanese Circulation Society. A total of 155 patients underwent surgery for AS between January 2020 and December 2021. Variables included age, sex, risk score, preoperative left ventricular ejection fraction, hypertension, and renal dysfunction. AKI was defined in accordance with the Kidney Disease: Improving Global Outcomes criteria. A total of 33 SAVR and 79 TAVI procedures were included in this study. The incidences of AKI in the SAVR and TAVI groups were 45.5% and 43.0%, respectively. No significant differences existed between the two groups. Weight (p = 0.0392) and pre-renal dysfunction (p = 0.0308) affected the incidence of AKI in the SAVR group, whereas no such variables were identified in the TAVI group. Within the current age-based treatment selection criteria for AS, no significant difference in the incidence of AKI was observed between the two procedures.Although preoperative renal function may be associated with postoperative AKI, further studies are required to select the optimal surgical procedure for patients with renal dysfunction.

Abstract
BACKGROUND Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis (AS), but despite estimates of life expectancy after TAVI being essential in heart team discussion, these data are scarce. Therefore, the current study sought to assess long-term survival and its trends in relation to chronological age, surgical risk, and treatment period. METHODS AND RESULTS We included 2,414 consecutive patients who underwent TAVI for severe symptomatic AS between 2008 and 2021 at 2 international centers. For the analysis, long-term survival was evaluated according to age, surgical risk, and treatment period categorized into 3 groups, respectively. The longest follow-up was 13.5 years. Overall survival was 67.6% at 5 years and 26.9% at 10 years. Younger patients, lower surgical risk, and later treatment period showed better survival (log-rank P<0.001, respectively). In the multivariate analysis, age <75years, lower surgical risk, and later time period were significantly associated with better survival. The incidence of paravalvular leakage ≥moderate, red blood cell transfusion, and acute kidney injury were independently associated with increasing risk of 5-year death. CONCLUSIONS In a real-world registry, survival was substantial following TAVI, especially in younger and lower surgical-risk patients, with improving outcomes over time. This should be considered in heart team discussions of life-long management for AS patients after TAVI.

Abstract
BACKGROUND Extracellular volume fraction (ECV) on magnetic resonance imaging can predict prognosis after aortic valve replacement in patients with aortic stenosis (AS). However, the usefulness of ECV on computed tomography (CT) for patients who have undergone transcatheter aortic valve replacement (TAVR) is unclear, so we investigated whether ECV analysis on CT is associated with clinical outcomes in TAVR candidates. METHODS AND RESULTS We analyzed 127 patients with severe AS who underwent preoperative CT for TAVR. We evaluated the utility of ECV analysis on single-energy CT for predicting patient prognosis after TAVR. The primary outcome was a composite of all-cause death and hospitalization due to heart failure (HF) after TAVR. 15 patients (12%) had composite outcomes: 4 deaths and 11 hospitalizations due to HF. In multivariate survival analysis using the Cox proportional hazard model, atrial fibrillation (AF) (hazard ratio (HR), 7.86; 95% confidence interval (CI), 2.57-24.03; P<0.001), history of congestive HF (HR, 4.91; 95% CI, 1.49-16.2; P=0.009) and ECV ≥32.6% on CT (HR, 6.96; 95% CI, 1.92-25.12; P=0.003) were independent predictors of composite outcomes. On Kaplan-Meier analysis, the higher ECV group (≥32.6%) had a significantly greater number of composite outcomes than the lower ECV group (P<0.001). CONCLUSIONS ECV on CT is an independent predictor of prognosis after TAVR.

Abstract
This study retrospectively evaluated the mid-term outcomes of surgical aortic valve replacement (SAVR) using a stented porcine aortic valve bioprosthesis (Mosaic; Medtronic Inc., Minneapolis, MN, USA) with concomitant mitral valve (MV) repair. From 1999 to 2014, 157 patients (median [interquartile range] age, 75 [70-79] years; 47% women) underwent SAVR with concomitant MV repair (SAVR + MV repair), and 1045 patients (median [interquartile range] age, 76 [70-80] years; 54% women) underwent SAVR only at 10 centers in Japan as part of the long-term multicenter Japan Mosaic valve (J-MOVE) study. The 5-year overall survival rate was 81.5% ± 4.1% in the SAVR + MV repair group and 85.1% ± 1.4% in the SAVR only group, and the 8-year overall survival rates were 75.2% ± 5.7% and 78.1% ± 2.1%, respectively. Cox proportional hazards analysis showed no significant difference in the survival rates between the two groups (hazard ratio, 0.87; 95% confidence interval, 0.54-1.40; P = 0.576). Among women with mild or moderate mitral regurgitation who were not receiving dialysis, those who underwent SAVR + MV repair, were aged > 75 years, and had a preoperative left ventricular ejection fraction of 30-75% tended to have a lower mortality risk. In conclusion, this subgroup analysis of the J-MOVE cohort showed relevant mid-term outcomes after SAVR + MV repair.

Abstract
Stress echocardiography has been one of the most promising methods for the diagnosis of ischemic heart disease, hypertrophic cardiomyopathy, and pulmonary hypertension. The Japanese Society of Echocardiography produced practical guidance for the implementation of stress echocardiography in 2018. At that time, stress echocardiography was not yet widely disseminated in Japan; therefore, the 2018 practical guidance for the implementation of stress echocardiography included a report on stress echocardiography and a specific protocol to promote its use at many institutions in Japan in the future. And now, an era of renewed interest and enthusiasm surrounding the diagnosis and treatment of valvular heart disease and heart failure with preserved ejection fraction (HFpEF) has come, which are driven by emerging trans-catheter procedures and new recommended guideline-directed medical therapy. Based on the continued evidence of stress echocardiography, the new practical guideline that describes the safe and effective methodology of stress echocardiography is now created by the Guideline Development Committee of the Japanese Society of Echocardiography and is designed to expand the use of stress echocardiography for valvular heart disease and HFpEF, as well as ischemic heart disease, hypertrophic cardiomyopathy, and pulmonary hypertension. The readers are encouraged to perform stress echocardiography which will enhance the diagnosis and management of these patients.

Abstract
In a world increasingly confronted by cardiovascular diseases (CVDs) and an aging population, accurate risk assessment prior to cardiac surgery is critical. Although effective, traditional risk calculators such as the Japan SCORE, Society of Thoracic Surgeons score, and EuroSCORE II may not completely capture contemporary risks, particularly due to emerging factors such as frailty and sarcopenia. These calculators often focus on regional and ethnic specificity and rely heavily on evaluations based on age and underlying diseases. Growth differentiation factor-15 (GDF-15) is a stress-responsive cytokine that has been identified as a potential biomarker for sarcopenia and a tool for future cardiac risk assessment. Preoperative plasma GDF-15 levels have been associated with preoperative, intraoperative, and postoperative factors and short- and long-term mortality rates in patients undergoing cardiac surgery. Increased plasma GDF-15 levels have prognostic significance, having been correlated with the use of cardiopulmonary bypass during surgery, amount of bleeding, postoperative acute kidney injury, and intensive care unit stay duration. Notably, the inclusion of preoperative levels of GDF-15 in risk stratification models enhances their predictive value, especially when compared with those of the N-terminal prohormone of brain natriuretic peptide, which does not lead to reclassification. Thus, this review examines traditional risk assessments for cardiac surgery and the role of the novel biomarker GDF-15. This study acknowledges that the relationship between patient outcomes and elevated GDF-15 levels is not limited to CVDs or cardiac surgery but can be associated with variable diseases, including diabetes and cancer. Moreover, the normal range of GDF-15 is not well defined. Given its promise for improving patient care and outcomes in cardiovascular surgery, future research should explore the potential of GDF-15 as a biomarker for postoperative outcomes and target therapeutic intervention.

Abstract
BACKGROUND Cardiovascular events are increasing in patients with supranormal left ventricular ejection fraction (snLVEF). However, the effect of snLVEF in patients with aortic stenosis (AS) remains unclear, especially in patients with moderate AS. HYPOTHESIS This study aimed to evaluate the prognosis of mortality and heart failure (HF) in patients with LVEF ≥ 50% and moderate or severe AS. METHODS This retrospective study targeted patients with moderate or severe AS and LVEF > 50%. LVEF of 50%-65% was classified as normal LVEF (nLVEF, nEF group) and >65% as snLVEF (snEF group). AS severity was stratified based on the aortic valve area into moderate (1.0-1.5 cm²) and severe (<1.0 cm²). Primary outcomes included all-cause mortality and HF hospitalization. RESULTS A total of 226 participants were included in this study. There were 67 and 65 participants with moderate AS in snEF (m-snEF) and nEF groups (m-nEF), respectively, and 41 and 53 participants with severe AS in the snEF (s-snEF) and nEF groups (s-nEF), respectively. During the observation period (median: 554 days), the primary composite outcome occurred in 108 individuals. Cox hazard analysis revealed no significant differences among the four groups in primary composite outcomes. With respect to HF hospitalization, the adjusted hazard ratios (95% confidence intervals) with m-snEF as the reference were as follows: m-nEF, 0.41 (0.19-0.89); s-nEF, 1.43 (0.76-2.67); and s-snEF, 1.83 (1.00-3.35). CONCLUSIONS The risk of HF hospitalization for m-snLVEF was higher than m-nLVEF and not significantly different from s-nLVEF.

Abstract
BACKGROUND To investigate the impact of peak aortic jet velocity (Vmax) on the prognosis of patients undergoing open surgery for chronic limb threatening ischemia (CLTI). METHODS Between April 2015 and March 2022, 352 patients underwent infrainguinal open surgery for CLTI. Patients who met the following exclusion criteria were excluded: subsequent infrainguinal surgeries in the registered period, no record of Vmax, history of aortic valve intervention, and Vmax ≥3.0 m/s (moderate or severe aortic valve stenosis). The remaining patients were dichotomized into 2 groups based on their Vmax values. The Youden index calculated from the receiver operating characteristic curve (ROC) was set as the cutoff value. The 2-year overall survival (OS), calculated using the Kaplan-Meier's method, was compared between the 2 groups. A Cox proportional hazards regression analysis was performed using perioperative factors including Vmax to identify independent predictors separately for dialysis and nondialysis patients and the quantitative relationship between Vmax and OS. RESULTS One hundred and ninety-one patients, including 100 dialysis and 91 nondialysis patients, were included in the analysis. The Youden index was 1.7 m/s. The 2-year OS rates of the group with Vmax >1.7 m/s and with Vmax ≤1.7 m/s were 49% and 76% (P = 0.007), respectively, in the dialysis cohort, while they were 71% and 78% (P = 0.680) in the nondialysis cohort, respectively. Multivariate analysis identified Vmax and ejection fraction as independent predictors in the dialysis cohort and the Barthel Index at admission in the nondialysis cohort. There was a stepwise increase in the risk of death in patients with Vmax of ≥1.5 m/s and a significantly higher risk of death in dialysis patients with Vmax >2.5 m/s. CONCLUSIONS Vmax was a significant independent predictor of all-cause death within 2 years after open surgery for CLTI in dialysis patients but not in patients managed without dialysis.

Risk of Sinus Sequestration During Redo Transcatheter Aortic Valve Implantation: The Prevalence, Predictors, and Risk Stratification. Am J Cardiol 2024; 211:1-8. [PMID: 37884114 DOI: 10.1016/j.amjcard.2023.10.058] [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: 08/14/2023] [Revised: 10/18/2023] [Accepted: 10/19/2023] [Indexed: 10/28/2023]
Abstract
The number of patients who underwent transcatheter aortic valve implantation (TAVI) with the potential for reintervention is steadily increasing; however, there is a risk of sinus sequestration (SS) during a redo TAVI. The prevalence, predictors, and risk stratification of the risk for SS remain uncertain. We analyzed computed tomography acquired from 263 patients who underwent TAVI between 2021 and 2022: balloon-expandable valve (BEV) (71%) and self-expandable valve (SEV) (29%). Patients were considered at risk for SS if they met the following: (1) BEV frame > sinotubular junction (STJ) or SEV neocommissure greater than the STJ and (2) valve-to-STJ <2 mm. The risk of left, right, and any SS in 51%, 50%, and 65%, respectively, did not differ between BEV and SEV. The predictors of any SS were the height of the left and right coronary cusp (odds ratio [OR] 0.81 and 0.71, cutoff 18.6 and 19.2 mm, respectively) and STJ minus the annulus diameter (OR 0.65, cutoff 3.7 mm) in BEV, and STJ diameter (OR 0.47, cutoff 27.6 mm) in SEV. The number of predictors stratified the risk of any SS: low risk with BEV at 0 predictors (14% at risk of SS), intermediate risk at 1 predictor (65%), high risk at 2 or 3 predictors (81% and 95%), and low risk with SEV at 0 predictors (33%) versus high risk at 1 predictor (91%). In conclusion, 2/3 of patients who underwent TAVI were at risk of SS. The height of the coronary cusp and the STJ diameter were associated with and adequately stratified the risk of SS.
