Abstract
Background Few reports on pre-existing left bundle branch block (LBBB) in patients undergoing transcatheter aortic valve replacement (TAVR) are currently available. Further, no present studies compare patients with new onset LBBB with those with pre-existing LBBB. Objectives This study aimed to investigate the association between pre-existing or new onset LBBB and clinical outcomes after TAVR. Methods Using data from the Japanese multicenter registry, 5,996 patients who underwent TAVR between October 2013 and December 2019 were included. Patients were classified into 3 groups: no LBBB, pre-existing LBBB, and new onset LBBB. The 2-year clinical outcomes were compared between 3 groups using Cox proportional hazards models and propensity score analysis to adjust the differences in baseline characteristics. Results Of 5,996 patients who underwent TAVR, 280 (4.6%) had pre-existing LBBB, while 1,658 (27.6%) experienced new onset LBBB. Compared with the no LBBB group, multivariable Cox regression analysis showed that pre-existing LBBB was associated not only with a higher 2-year all-cause (adjusted HR: 1.39; 95% CI: 1.06-1.82; P = 0.015) and cardiovascular (adjusted HR: 1.60; 95% CI: 1.04-2.48; P = 0.031) mortality, but also with higher all-cause (adjusted HR: 1.43, 95% CI: 1.07-1.91; P = 0.016) and cardiovascular (adjusted HR: 1.81, 95% CI:1.12-2.93; P = 0.014) mortality than the new onset LBBB group. Heart failure was the most common cause of cardiovascular death, with more heart failure deaths in the pre-existing LBBB group. Conclusions Pre-existing LBBB was independently associated with poor clinical outcomes, reflecting an increased risk of cardiovascular mortality after TAVR. Patients with pre-existing LBBB should be carefully monitored.

Abstract
BACKGROUND Renal congestion is a potential prognostic factor in patients with heart failure and recently, assessment has become possible with intrarenal Doppler ultrasonography (IRD). The association between renal congestion assessed by IRD and outcomes after mitral transcatheter edge-to-edge repair (TEER) is unknown, so we aimed to clarify renal congestion and its prognostic implications in patients with mitral regurgitation (MR) who underwent TEER using MitraClip system.Methods and Results: Patients with secondary MR who underwent TEER and were assessed for intrarenal venous flow (IRVF) by IRD were classified according to their IRVF pattern as continuous or discontinuous. Of the 105 patients included, 78 patients (74%) formed the continuous group and 27 (26%) were the discontinuous group. Kaplan-Meier analysis revealed significant prognostic power of the IRVF pattern for predicting the composite outcome of all-cause death and heart failure rehospitalization (log-rank P=0.0257). On multivariate Cox regression analysis, the composite endpoint was independently associated with the discontinuous IRVF pattern (hazard ratio, 3.240; 95% confidence interval, 1.300-8.076; P=0.012) adjusted using inverse probability of treatment weighting. CONCLUSIONS IRVF patterns strongly correlated with clinical outcomes without changes in renal function. Thus, they may be useful for risk stratification after mitral TEER for patients with secondary MR.

Abstract
BACKGROUND The MitraClip G4 system is a new iteration of the transcatheter edge-to-edge repair system. We assessed the impact of the G4 system on routine practice and outcomes in secondary mitral regurgitation (2°MR).Methods and Results: Consecutive patients with 2°MR treated with either the MitraClip G2 (n=89) or G4 (n=63) system between 2018 and 2021 were included. Baseline characteristics, procedures, and outcomes were compared. Inverse probability of treatment weighting and Cox regression were used to adjust for baseline differences. Baseline characteristics were similar, except for a lower surgical risk in the G4 group (Society of Thoracic Surgeons Predicted Risk of Mortality ≥8: 38.1% vs. 56.2%; P=0.03). In the G4 group, more patients had short (≤2 mm) coaptation length (83.7% vs. 54.0%; P<0.001) and fewer clips were used (17.5% vs. 36.0%; P=0.02). Acceptable MR reduction was observed in nearly all patients, with no difference between the G4 and G2 groups (100% vs. 97.8%, respectively; P=0.51). The G4 group had fewer patients with high transmitral gradients (>5mmHg; 3.3% vs. 13.6%; P=0.03). At 1 year, there was no significant difference between groups in the composite endpoint (death or heart failure rehospitalization) after baseline adjustment (10.5% vs. 20.2%; hazard ratio 0.39; 95% confidence interval 0.11-1.32; P=0.13). CONCLUSIONS The G4 system achieved comparable device outcomes to the early-generation G2, despite treating more challenging 2°MR with fewer clips.

Abstract
Background: Transthoracic echocardiography (TTE) is the gold standard modality for evaluating cardiac morphology, function, and hemodynamics in clinical practice. While artificial intelligence (AI) is expected to contribute to improved accuracy and is being applied clinically, its impact on daily clinical practice has not been fully evaluated. Methods: We retrospectively examined 30 consecutive patients who underwent AI-equipped TTE at a single institution. All patients underwent manual and automatic measurements of TTE parameters using the AI-equipped TTE. Measurements were performed by three sonographers with varying experience levels: beginner, intermediate, and expert. Results: A comparison between the manual and automatic measurements assessed by the experts showed extremely high agreement in the left ventricular (LV) filling velocities (E wave: r = 0.998, A wave: r = 0.996; both p < 0.001). The automated measurements of LV end-diastolic and end-systolic diameters were slightly smaller (-2.41 mm and -1.19 mm) than the manual measurements, although without significant differences, and both methods showing high agreement (r = 0.942 and 0.977, both p < 0.001). However, LV wall thickness showed low agreement between the automated and manual measurements (septum: r = 0.670, posterior: r = 0.561; both p < 0.01), with automated measurements tending to be larger. Regarding interobserver variabilities, statistically significant agreement was observed among the measurements of expert, intermediate, and beginner sonographers for all the measurements. In terms of measurement time, automatic measurement significantly reduced measurement time compared to manual measurement (p < 0.001). Conclusions: This preliminary study confirms the accuracy and efficacy of AI-equipped TTE in routine clinical practice. A multicenter study with a larger sample size is warranted.

Abstract
BACKGROUND Transcatheter aortic valve replacement (TAVR) for severe symptomatic aortic stenosis (AS) does not benefit all patients. We performed a prospective multicenter study to investigate the cost-effectiveness of TAVR in a Japanese cohort. METHODS AND RESULTS We prospectively enrolled 110 symptomatic patients with severe AS who underwent TAVR from five institutions. The quality of life measurement (QOL) was performed for each patient before and at 6 months after TAVR. Patients without an improvement in QOL at 6 months after TAVR were defined as non-responders. Pre-TAVR higher QOL, higher clinical frailty scale predicted the non-responders. Three models, 1) conservative treatment for all patients strategy, 2) TAVR for all patients strategy, and 3) TAVR for a selected patient strategy who is expected to be a responder, were simulated. Lifetime cost-effectiveness was estimated using incremental cost-effectiveness ratio (ICER) and cost per quality-adjusted life-year (QALY) gained. In comparison to conservative therapy for all patients, ICER was estimated to be 5,765,800 yen/QALY for TAVR for all patients and 2,342,175 yen/QALY for TAVR for selected patient strategy patients, which is less than the commonly accepted ICER threshold of 5,000,000 yen/QALY. CONCLUSIONS TAVR for selected patient strategy model is more cost-effective than TAVR for all patient strategy without reducing QOL in the Japanese healthcare system. TAVR for selected patient strategy has potential benefit for optimizing the TAVR treatment in patients with high frailty and may direct our resources toward beneficial interventions.

Abstract
Aims Current evidence on the prognostic value of exercise stress echocardiography (ESE) in asymptomatic patients with low-gradient severe aortic stenosis (AS) is limited. Therefore, this study aimed to elucidate its prognostic implications for patients with low-gradient severe AS and determine the added value of ESE in risk stratification for this population. Methods and results This retrospective observational study included 122 consecutive asymptomatic patients with either moderate [mean pressure gradient (MPG) < 40 mmHg and aortic valve area (AVA) 1.0-1.5 cm2] or low-gradient severe (MPG < 40 mmHg and AVA < 1.0 cm2) AS and preserved left ventricular ejection fraction (≥50%) who underwent ESE. All patients were followed up for AS-related events. Of 143 patients, 21 who met any exclusion criteria, including early interventions, were excluded, and 122 conservatively managed patients [76.5 (71.0-80.3) years; 48.3% male] were included in this study. During a median follow-up period of 989 (578-1571) days, 64 patients experienced AS-related events. Patients with low-gradient severe AS had significantly lower event-free survival rates than those with moderate AS (log-rank test, P < 0.001). Multivariable Cox regression analysis showed that the mitral E/e' ratio during exercise was independently associated with AS-related events (hazard ratio = 1.075, P < 0.001) in patients with low-gradient severe AS. Conclusion This study suggests that asymptomatic patients with low-gradient severe AS have worse prognoses than those with moderate AS. Additionally, the mitral E/e' ratio during exercise is a useful parameter for risk stratification in patients with low-gradient severe AS.

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
A 70-year-old patient with paroxysmal atrial fibrillation underwent left atrial appendage closure. The patient experienced transient hypotension during device implantation. The procedure was abandoned because of ST-T-wave changes on electrocardiography and elevated coronary flow velocity on transesophageal echocardiography, which indicated that the device caused coronary artery compression.

Abstract
Background: Transcatheter edge-to-edge mitral valve repair (TEER) has emerged as a viable approach to addressing substantial secondary mitral regurgitation. In the contemporary landscape where ultimate heart failure-specific therapies, such as cardiac replacement modalities, are available, prognosticating a high-risk cohort susceptible to early cardiac mortality post-TEER is pivotal for formulating an effective therapeutic regimen. Methods: Our study encompassed individuals with secondary mitral regurgitation and chronic heart failure enlisted in the multi-center (Optimized CathEter vAlvular iNtervention (OCEAN)-Mitral registry. We conducted an assessment of baseline variables associated with cardiac death within one year following TEER. Results: Amongst the 1517 patients (median age: 78 years, 899 males), 101 experienced cardiac mortality during the 1-year observation period after undergoing TEER. Notably, a history of heart failure-related admissions within the preceding year, utilization of intravenous inotropes, and elevated plasma B-type natriuretic peptide levels emerged as independent prognosticators for the primary outcome (p < 0.05 for all). Subsequently, we devised a novel risk-scoring system encompassing these variables, which significantly stratified the cumulative incidence of the 1-year primary outcome (16%, 8%, and 4%, p < 0.001). Conclusions: Our study culminated in the development of a new risk-scoring system aimed at predicting 1-year cardiac mortality post-TEER.

Abstract
Aortic stenosis is a prevalent valvular heart disease, especially in the older people. They often coexist with other co-morbidities, and noncardiac surgery carries a higher risk because of the underlying valve condition. Despite the growing concern about the safety and optimal management of noncardiac surgery post-transcatheter aortic valve replacement (TAVR), there is limited evidence on this matter. This study aims to assess the clinical outcomes of noncardiac surgeries after TAVR. This retrospective study included 718 patients who underwent TAVR. Of these, 36 patients underwent noncardiac surgery after TAVR. The primary end point was the incidence of cardiovascular adverse events post-TAVR and the secondary end point was the incidence of structural valve deterioration. Composite end points included disabling stroke, heart failure requiring hospitalization, and cardiac death as defined by Valve Academic Research Consortium 3. Most of these surgeries were orthopedic and classified as intermediate risk. All noncardiac surgeries were performed without perioperative adverse events. There was no observed structural valve deterioration, and the incidence of composite end points did not significantly differ between the surgical and nonsurgical groups during the follow-up period. Noncardiac surgery after TAVR can be performed safely and does not have a negative impact on prognosis. Further studies are warranted to determine the optimal strategy for noncardiac surgery after TAVR.

Abstract
BACKGROUNDS There are limited data on the clinical relevance of transvalvular flow rate (Qmean ) at rest (Qrest) and at peak stress (Qstress ) during dobutamine stress echocardiography (DSE) in patients with low-gradient severe aortic stenosis (LG-SAS). METHODS We retrospectively analyzed the clinical data of patients with LG-SAS who underwent DSE. LG-SAS was defined as an aortic valve (AV) area index of < .6 cm2 /m2 and a mean AV pressure gradient (AVPG) of < 40 mm Hg. The primary endpoint included all-cause death and heart failure hospitalization. RESULTS Of 100 patients (mean age 79.5 ± 7.3 years; men, 45.0%; resting left ventricular ejection fraction [LVEF] 52.1% ± 15.9%; resting stroke volume index 35.8 ± 7.7 mL/m2 ; Qrest 171.8 ± 34.9 mL/s), the primary endpoint occurred in 51 patients during a median follow-up of 2.84 (interquartile range 1.01-5.21) years. When the study patients were divided into three subgroups based on Qrest and Qstress , the multivariate analysis showed that Qrest < 200 mL/s and Qstress ≥200 mL/s (hazard ratio 3.844; 95% confidence interval 1.143-12.930; p = .030), as well as Qrest and Qstress < 200 mL/s (hazard ratio 9.444; 95% confidence interval 2.420-36.850; p = .001), were significantly associated with unfavorable outcomes with Qrest and Qstress ≥200 mL/s as a reference after adjusting for resting LVEF, resting mean AVPG, chronic kidney disease, New York Heart Association functional class III/IV, and AV replacement. CONCLUSIONS Flow conditions based on the combination of Qrest and Qstress are helpful for risk stratification in LG-SAS patients.

Abstract
BACKGROUND Aortic stenosis (AS) and chronic kidney disease (CKD) can coexist. Repeat exposure to contrast media in patients undergoing transcatheter aortic valve implantation (TAVI) has latent mortality risks and increased risk for acute kidney injury. We aimed to assess our "zero-contrast TAVI" protocol for patients with advanced CKD. METHODS Consecutive patients with severe AS who underwent TAVI at a single center registry were enrolled. Zero-contrast TAVI group included patients who underwent TAVI without contrast and who had an estimated glomerular filtration rate <30 mL/min/1.73 m2. Conventional TAVI group included patients who underwent the regular TAVI procedure. Patients using balloon-expandable valves via transfemoral approach were analyzed. Baseline clinical and procedural characteristics and clinical outcomes were compared between two groups. The primary outcome was early safety as defined by Valve Academic Research Consortium Criteria. Secondary outcomes included the presence of severe prosthesis-patient mismatch, moderate or greater perivalvular leakage, and requirement for new dialysis (within 3 months). RESULTS A total of 520 patients were analyzed. Among these, 32 (6 %) underwent zero-contrast TAVI and 488 (94 %) conventional TAVI. In the zero-contrast TAVI group, 12 patients (37.5 %) had to use 20.7 (11.0-31.2) mL of contrast media. There were no significant differences in the primary and secondary outcomes between zero-contrast TAVI and conventional TAVI groups (78.1 % vs. 86.8 %, P = 0.184 and 9.4 % vs. 8.1 %, P = 0.738 for the primary and secondary outcomes, respectively). CONCLUSIONS Zero-contrast TAVI is feasible, safe, and effective in patients with AS and stage 4 CKD.

Abstract
The safety and feasibility are still not well known for exercise-induced mitral regurgitation (MR). This study is aimed to assess and compare the hemodynamic and symptomatic changes in patients with significant secondary MR during exercise stress echocardiography (ESE) before and after transcatheter edge-to-edge repair (TEER). The study included a total of 15 patients with secondary MR who underwent ESE before and after TEER using the MitraClip system (Abbott, Abbott Park, IL, USA). Echocardiographic data of ESE were collected both before the procedure and during the follow-up visit at 3 months. During the one-year postoperative observation period, the rate of readmission due to heart failure was 13% (n = 2), with no recorded fatalities. Although no significant differences of ESE data were observed in exercise-induced pulmonary hypertension or cardiac output before and after the repair, the severity of MR was significantly improved after the procedure, both at rest (2 [2-3] vs. 1 [1-2], p = 0.0125) and during ESE (3 [3-3] vs. 1 [1-1], p < 0.0001). Furthermore, the New York Heart Association Functional Classification was improved (3 [3-3] vs. 1 [1-1], p < 0.0001) after treatment. For a supplemental analysis, MR during ESE was significantly improved not only in cases with atrial secondary MR but also in ventricular secondary MR. Transcatheter edge-to-edge repair for exercise-induced MR resulted in a significant improvement in postoperative MR severity and subjective symptoms. These results are novel, as they have not been extensively reported previously, particularly among Japanese patients.

Abstract
Valvular heart disease (VHD) has been a significant health problem, particularly in developed countries, in relation to the aging population. Recent developments in the management of VHD require a more accurate assessment of disease severity to determine the need for transcatheter interventions or open heart surgery. Stress echocardiography is a crucial imaging modality for identifying the underlying pathology of VHD. Optimal administration of exercise or intravenous drugs may reveal hemodynamic abnormalities under stress without posing an invasive risk. Therefore, the implementation of stress echocardiography is recommended for determining interventional indications and risk stratification in mitral regurgitation and aortic stenosis. In addition, recent evidence has accumulated regarding the usefulness of stress echocardiography in various conditions including mitral stenosis, aortic regurgitation, and post-interventional VHD. Here, we summarize the current evidence and future perspectives on stress echocardiography in VHD.

Abstract
Background: A high score for controlling nutritional status (CONUT) due to poor nutritional status has been associated with adverse outcomes in patients with chronic heart failure. However, because little is known about the effect of CONUT score on mortality rates after transcatheter mitral valve repair, we evaluated nutrition screening tools for prognosis prediction in patients undergoing transcatheter mitral valve repair using the MitraClipTM system. Methods and Results: We retrospectively analyzed 148 patients with severe mitral regurgitation (MR) who underwent MitraClipTM implantation between April 2018 and April 2021. The preprocedural CONUT scores were assessed at the time of hospitalization, the primary outcome was all-cause death, and the analysis was of the mortality and incidence rates of cardiac events 1 year post-operation. Functional MR was of ischemic origin in the majority of patients (69.6%), with a mean left ventricular ejection fraction of 48.9±15.8%. Kaplan-Meier curves indicated that all-cause death was significantly worse in the high-CONUT score group than in the low-CONUT score group. Cox hazard analysis showed a significant association between all-cause death and CONUT score, as well as MitraScore. Conclusions: Preprocedural CONUT score, as well as MitraScore, in patients undergoing transcatheter edge-to-edge mitral valve repair may predict an increased risk of all-cause death. This knowledge should allow the heart team to accurately assess the clinical implications and prognostic benefits of the procedure in individual patients.

Abstract
Weather conditions influence the incidence of cardiovascular disease. However, few studies have investigated the association between weather temperature and humidity and cerebrovascular disease hospitalizations in a super-aging society. We included 606,807 consecutive patients with cerebrovascular disease admitted to Japanese acute-care hospitals between 2015 and 2019. The primary outcome was the number of cerebrovascular disease hospitalizations per day. Multilevel mixed-effects linear regression models were used to estimate the association of mean temperature and humidity, 1 day before hospital admission, with cerebrovascular disease hospitalizations, after adjusting for air pollution, hospital, and patient demographics. Lower mean temperatures and humidity < 70% or humidity ≧ 70% are associated with an increased incidence of cerebrovascular disease hospitalization (coefficient, - 1.442 [- 1.473 to - 1.411] per °C, p < 0.001, coefficient, - 0.084 [- 0.112 to - 0.056] per%, p < 0.001, and coefficient, 0.136 [0.103 to 0.168] per %, p < 0.001, respectively). Lower mean temperatures and extremely lower or higher humidity are associated with an increased incidence of cerebrovascular disease hospitalization in a super-aging society.

Abstract
BACKGROUND Despite the wide implementation of transcatheter aortic valve implantation (TAVI), the optimal antithrombotic therapy after TAVI has not been established yet. Owing to the accumulating evidence supporting the efficacy and safety of single antiplatelet therapy (SAPT) over dual antiplatelet therapy, the latest guideline recommends life-long SAPT. However, there is scarce evidence supporting SAPT compared with non-antithrombotic therapy. Given the vulnerability of patients undergoing TAVI in terms of high bleeding risk, the benefit of SAPT may be canceled out by its potential increased bleeding risk. STUDY DESIGN AND OBJECTIVES Non-antithrombotic Therapy After Transcatheter Aortic Valve Implantation (NAPT) Trial is a prospective, randomized controlled, open-label blinded endpoint multicenter trial conducted in Japan, testing the non-inferiority of non-antithrombotic therapy compared with aspirin monotherapy in patients who underwent TAVI and had no indications for long-term oral anticoagulation therapy (OAC). Patients who successfully underwent trans-femoral TAVI for severe aortic stenosis with either balloon-expandable or self-expandable valves are eligible for inclusion. Key exclusion criteria are (i) occurrence of perioperative complications (ii) indications of taking antithrombotic drugs for other reasons; (iii) eGFR <30 ml/min/1.73 m2 or hemodialysis or peritoneal dialysis. A total of 360 patients will be randomized (1:1) to aspirin monotherapy vs. non-antithrombotic therapy. The primary outcome is a composite of all-cause mortality, myocardial infarction, stroke, and bleeding. All bleeding events based on the Valve Academic Research Consortium 3 are included as a component of the primary outcome. CONCLUSION The NAPT trial will determine the non-inferiority of a non-antithrombotic therapy compared with aspirin monotherapy after TAVI.

Abstract
Background Limited data are available about clinical outcomes and residual mitral regurgitation (MR) after transcatheter edge-to-edge repair in the large Asian-Pacific cohort. Methods and Results From the Optimized Catheter Valvular Intervention (OCEAN-Mitral) registry, a total of 2150 patients (primary cause of 34.6%) undergoing transcatheter edge-to-edge repair were analyzed and classified into 3 groups according to the residual MR severity at discharge: MR 0+/1+, 2+, and 3+/4+. The mortality and heart failure hospitalization rates at 1 year were 12.3% and 15.0%, respectively. Both MR and symptomatic improvement were sustained at 1 year with MR ≤2+ in 94.1% of patients and New York Heart Association functional class I/II in 95.0% of patients. Compared with residual MR 0+/1+ (20.4%) at discharge, both residual MR 2+ (30.2%; P < 0.001) and 3+/4+ (32.4%; P = 0.007) were associated with the higher incidence of death or heart failure hospitalization (adjusted hazard ratio [HR], 1.59; P < 0.001, and adjusted HR, 1.73; P = 0.008). New York Heart Association class III/IV at 1 year was more common in the MR 3+/4+ group (20.0%) than in the MR 0+/1+ (4.6%; P < 0.001) and MR 2+ (6.4%; P < 0.001) groups, and the proportion of New York Heart Association class I is significantly higher in the MR 1+ group (57.8%) than in the MR 2+ group (48.3%; P = 0.02). Conclusions The OCEAN-Mitral registry demonstrated favorable clinical outcomes and sustained MR reduction at 1 year in patients undergoing transcatheter edge-to-edge repair. Both residual MR 2+ and 3+/4+ after transcatheter edge-to-edge repair at discharge were associated with worse clinical outcomes compared with residual MR 0+/1+.

Abstract
Recent studies suggested short-term mortality after transcatheter edge-to-edge repair (TEER) was comparable between men and women. However, the gender-specific prognostic difference in the long-term follow-up after TEER is still unknown. To evaluate the impact of gender on long-term mortality after TEER for functional mitral regurgitation (FMR) using multicenter registry data. We retrospectively analyzed 1,233 patients (male 60.3%) who underwent TEER for FMR at 24 centers. The impact of gender on all-cause death and hospitalization for heart failure (HF) after TEER was evaluated using multivariate regression analysis and propensity score (PS) matching methods. During the 2-year follow-up, 207 all-cause death and 263 hospitalizations for HF were observed after TEER for FMR. Men had a significantly higher incidence of all-cause death than women (18.6% vs 14.1%, log-rank p = 0.03). After adjustment by multivariate Cox regression and PS matching, the male gender was significantly associated with a higher incidence of all-cause mortality after TEER than the female gender (hazard ratio 2.11, 95% confidence interval 1.42 to 3.14 in multivariate Cox regression; hazard ratio 1.89, 95% confidence interval 1.03 to 3.48 in PS matching). The gender-specific prognostic difference was even more pronounced after 1-year of TEER. On the contrary, there was no gender-related difference in hospitalization for HF after TEER. In conclusion, women with FMR had a better prognosis after TEER than men, whereas this was not observed in hospitalization for HF. This result might indicate that women with FMR are more likely to benefit from TEER.

Abstract
Electrocardiogram (ECG) left ventricular hypertrophy (LVH) is associated with the prognosis of patients with aortic stenosis. However, the impact of the presence or absence of ECG-LVH on the clinical outcomes after transcatheter aortic valve implantation (TAVI) is limited. This study aimed to assess the prognostic value of ECG-LVH among patients with aortic stenosis treated by TAVI. A total of 1,667 patients who underwent TAVI were prospectively enrolled into the OCEAN-TAVI (Optimized CathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation) registry. A total of 1,446 patients (mean age 84 years; 29.9% men) were analyzed. The Sokolow-Lyon index was used to determine the presence of ECG-LVH. LVH was also assessed using transthoracic echocardiography (TTE). We investigated the association between ECG-LVH and all-cause and cardiovascular mortality. This study identified ECG-LVH and TTE-LVH in 743 (51.5%) and 1,242 patients (86.0%), respectively. The Kaplan-Meier analysis revealed that all-cause mortality was significantly higher among patients without ECG-LVH than among those with ECG-LVH (log-rank p <0.001). In the multivariable analysis, the absence of ECG-LVH was independently associated with all-cause mortality (hazard ratio 1.98, 95% confidence interval 1.39 to 2.82, p <0.001), regardless of the presence or absence of TTE-LVH. Furthermore, the presence of TTE-LVH with the absence of ECG-LVH was observed in 575 patients (40%), which was associated with cardiovascular mortality (hazard ratio 2.84, 95% confidence interval 1.56 to 5.17, p <0.001). In conclusion, the absence of ECG-LVH was independently associated with an increased risk of all-cause mortality after TAVI. Risk stratification using both ECG-LVH and TTE-LVH is a useful predictor of adverse clinical outcomes after TAVI.

Abstract
Background: Very severe aortic stenosis (AS) has a poor prognosis even in asymptomatic patients, and asymptomatic very severe AS is a Class IIa indication for aortic valve replacement, although the safety and effectiveness of transcatheter aortic valve implantation (TAVI) for very severe AS is not well-established. Methods and Results: This study included 366 patients undergoing TAVI at a single center, with 85 and 281 patients in the very severe AS (peak velocity ≥5 m/s or mean pressure gradient (PG) ≥60 mmHg) and severe AS groups, respectively. Procedural and clinical outcomes at 1-year follow-up were compared between groups. The calcium scores were significantly higher in the very severe AS group (2,864.5 vs. 1,405.8 arbitrary units [AU] (P<0.001). Although the patient-prosthesis mismatch rate was higher in the very severe AS group (38.3% vs. 25.7%; P=0.029), there was no significant difference in the early safety and clinical efficacy between the groups (16.5% vs. 17.1% and 12.0% vs. 18.9%, respectively). Similarly, there was no significant difference in all-cause mortality at 1 year (4.8% vs. 9.8%). Conclusions: Despite a higher incidence of prosthesis-patient mismatch in those with very severe AS, the procedural and clinical outcomes were comparable to those in patients with severe AS. TAVI may be a reasonable treatment option for very severe AS.

Abstract
Background Information is scarce regarding the clinical implications of aortic valve replacement (AVR) for patients suffering from moderate mixed aortic valve disease (MAVD), characterized by a combination of moderate aortic stenosis (AS) and regurgitation (AR). The objective of this retrospective study was to explore the clinical effects of AVR in individuals with moderate MAVD. Methods We examined the clinical data from patients with moderate MAVD and preserved left ventricular ejection fraction, who had undergone echocardiography in the period spanning from 2010 to 2018. Moderate AS was defined as aortic valve area index of 0.60-0.85 cm2/m2 and peak velocity of 3.0-4.0 m/s. Moderate AR was defined as a vena contracta width of 3.0-6.0 mm. The primary endpoint was a composite of all-cause death and heart failure hospitalization. Results Among 88 patients (mean age, 74.4 ± 6.8 years; 48.9%, men), 44 (50.0%) required AVR during a median follow-up period of 3.3 years (interquartile range, 0.5-4.9). Mean values of specific aortic valve variables are as follows: aortic valve area index, 0.64 ± 0.04 cm2/m2; peak velocity, 3.40 ± 0.30 m/s; and vena contracta width, 4.1 ± 0.7 mm. The primary endpoint occurred in 32 (36.4%) patients during a median follow-up duration of 5.3 years (interquartile range, 3.2-8.0). Multivariable analysis revealed that AVR was significantly associated with the endpoint (hazard ratio, 0.248; 95% confidence interval, 0.107-0.579; p = 0.001) after adjusting for age, B-type natriuretic peptide, and the Charlson comorbidity index. Patients who underwent AVR during follow-up had significantly lower incidence rates of the endpoint than those managed with medical treatment (10.2% vs. 44.1% at 5 years; p < 0.001). Conclusions Approximately half of the patients diagnosed with moderate MAVD eventually necessitated AVR throughout the period of observation, leading to positive clinical results. Vigilant tracking of these patients and watchful monitoring for signs requiring AVR during this time frame are essential.

Abstract
Background Prognostic implications of transcatheter aortic valve implantation (TAVI) in low-gradient (LG) aortic stenosis (AS) remain controversial. The authors hypothesized that differences in cardiac functional recovery may solve this ongoing controversy. The aim was to evaluate clinical outcomes and the response of left ventricular (LV) function following TAVI in patients with LG AS. Methods and Results This multicenter retrospective study included 1742 patients with severe AS undergoing TAVI between January 2015 and March 2019. Patients were subdivided into low-flow (LF) LG, normal-flow (NF) LG, LF high-gradient, and NF high-gradient AS groups according to the mean gradient of the aortic valve (LG <40 mm Hg) and LV stroke volume index (LF <35 mL/m2). Outcomes and changes in echocardiographic parameters after TAVI were compared between the groups. A total of 227 patients (13%) had reduced ejection fraction, and 486 patients (28%) had LG AS (LF-LG 143 [8%]; NF-LG 343 [20%]). During a median follow-up period of 747 days, 301 patients experienced a composite end point of cardiovascular death and rehospitalization for cardiovascular events, which was higher in the LF-LG and NF-LG groups than in the high-gradient groups. LG AS was independently associated with the primary outcome (hazard ratio, 1.69; P<0.001). Among 1239 patients with follow-up echocardiography, LG AS showed less improvement in the LV mass index and LV end-diastolic volume compared with high-gradient AS after 1 year, while LV recovery was similar between the LF AS and NF AS groups. Conclusions LG AS was associated with poorer outcomes and LV recovery, regardless of flow status after TAVI. Careful evaluation of AS severity may be required in LG AS to provide TAVI within the appropriate time and advanced care afterward.

Abstract
Transcatheter structural heart intervention (TSHI) has gained popularity over the past decade as a means of cardiac intervention in patients with prohibitive surgical risks. Following the exponential rise in cases and devices developed over the period, there has been increased focus on developing the role of "structural imagers" amongst cardiologists. This review, as part of a growing initiative to develop the field of interventional echocardiography, aims to highlight the role of echocardiography in myriad TSHIs available within Asia. We first discuss the various echocardiography-based imaging modalities, including 3-dimensional echocardiography, fusion imaging, and intracardiac echocardiography. We then highlight a selected list of structural interventions available in the region-a combination of established interventions alongside novel approaches-describing key anatomic and pathologic characteristics related to the relevant structural heart diseases, before delving into various aspects of echocardiography imaging for each TSHI.

Abstract
Ventricular-demand leadless pacemakers (VVI-LPMs) have often been used as an alternative to atrioventricular (AV) synchronous transvenous pacemakers (DDD-TPMs) in patients with high-grade AV block following transcatheter aortic valve replacement (TAVR). However, the clinical outcomes of this unusual usage are not elucidated. Patients who received permanent pacemakers (PPMs) owing to new-onset high-grade AV block after TAVR from September 2017 to August 2020 at a high-volume center in Japan were included in the analysis, and the clinical courses of VVI-LPM and DDD-TPM implants through 2 years of follow-up were compared retrospectively. Out of 413 consecutive patients who underwent TAVR, 51 (12%) patients received a PPM. After excluding 8 patients with chronic atrial fibrillation (AF), 3 with sick sinus syndrome, and 1 with incomplete data, 17 VVI-LPMs and 22 DDD-TPMs were included in our final cohort. The VVI-LPM group had lower serum albumin levels (3.2 ± 0.5 vs. 3.9 ± 0.4 g/dL, P < .01) than the DDD-TPM group. Follow-up revealed no significant differences between the 2 groups in terms of the incidence of late device-related adverse events (0% vs. 5%, log-rank P = .38) and new-onset AF (6% vs. 9%, log-rank P = .75); however, there were increases in the rates of all-cause death (41% vs. 5%, log-rank P < .01) and heart failure rehospitalization (24% vs. 0%, log-rank P = .01) in the VVI-LPM group. This small retrospective study reveals favorable post-procedural complication rates but higher all-cause mortality with VVI-LPM compared to DDD-TPM therapy for high-grade AV block after TAVR at 2 years of follow-up.

Abstract
BACKGROUND No consensus exists on the efficacy of home-based cardiac rehabilitation (CR) in patients who have undergone transcatheter aortic valve implantation (TAVI). Additionally, there are no reports on home-based cardiac telemonitoring rehabilitation (HBTR) in patients after TAVI. OBJECTIVE We aimed to investigate the efficacy of HBTR in patients who have undergone TAVI. METHODS This single-center preliminary study introduced HBTR to patients after TAVI, and the efficacy outcomes of the rehabilitation method were compared to that of a historical control cohort. The historical control cohort (control group) consisted of 6 consecutive patients who underwent ordinary outpatient CR after TAVI from February 2016 to March 2020. Patients who participated in the HBTR program were only recruited after the TAVI procedure and before discharge between April 2021 and May 2022. In the first 2 weeks after TAVI, patients underwent outpatient CR and were trained using telemonitoring rehabilitation systems. Thereafter, patients underwent HBTR twice a week for 12 weeks. The control group performed standard outpatient CR at least once a week for 12 to 16 weeks. Efficacy was assessed using peak oxygen uptake (VO2) prior to and after CR. RESULTS Eleven patients were included in the HBTR group. All patients underwent 24 HBTR sessions during the 12-week training period, and no adverse events were observed. The control group participants performed 19 (SD 7) sessions during the training period, and no adverse events were observed. Participants in the HBTR and control groups had a mean age of 80.4 (SD 6.0) years and 79.0 (SD 3.9) years, respectively. In the HBTR group, preintervention and postintervention peak VO2 values were 12.0 (SD 1.7) mL/min/kg and 14.3 (SD 2.7) mL/min/kg (P=.03), respectively. The peak VO2 changes in the HBTR and control groups were 2.4 (SD 1.4) mL/min/kg and 1.3 (SD 5.0) mL/min/kg (P=.64), respectively. CONCLUSIONS Home-based CR using a telemonitoring system is a safe outpatient rehabilitation method. Its efficacy is not inferior to that of standard CR in patients who have undergone TAVI.

Abstract
Background: The left atrial volume index (LAVI) is important for predicting thromboembolism in patients with non-valvular atrial fibrillation (AF), but the utility of LAVI for predicting thromboembolism in patients with both bioprosthetic valve replacement and AF remains unclear. Methods and Results: Of 894 patients from a previous multicenter prospective observational registry (BPV-AF Registry), 533 whose LAVI data had been obtained by transthoracic echocardiography were included in this subanalysis. Patients were divided into tertiles (T1-T3) according to LAVI as follows: T1 (n=177), LAVI=21.5-55.3 mL/m2; T2 (n=178), LAVI=55.6-82.1 mL/m2; T3 (n=178), LAVI=82.5-408.0 mL/m2. The primary outcome was defined as either stroke or systemic embolism for a mean (±SD) follow-up period of 15.3±4.2 months. Kaplan-Meier curves indicated that the primary outcome tended to occur more frequently in the group with the larger LAVI (log-rank P=0.098). Comparison of T1 with T2 plus T3 using Kaplan-Meier curves indicated that patients in T1 experienced significantly fewer primary outcomes (log-rank P=0.028). Furthermore, univariate Cox proportional hazard regression showed that 1.3- and 3.3-fold more primary outcomes occurred in T2 and T3, respectively, than in T1. Conclusions: Larger LAVI was associated with stroke or systemic embolism in patients who had undergone bioprosthetic valve replacement and with a definitive diagnosis of AF.

Objectives This study summarizes the initial experience with LAAC in Japan and determines age-related clinical outcomes in patients with nonvalvular atrial fibrillation undergoing percutaneous LAAC. Methods In an ongoing, prospective, investigator-initiated, multicenter, observational registry of patients undergoing LAAC in Japan, we analyzed short-term clinical outcomes in patients with nonvalvular atrial fibrillation who underwent LAAC. Patients were classified into younger, middle-aged, and elderly groups (≤70, 70 to 80, and >80 years of age, respectively) to determine age-related outcomes. Results Patients (n = 548; mean age, 76.4 ± 8.1 years; male, 70.3%) who underwent LAAC at 19 Japanese centers between September 2019 and June 2021 were enrolled in the study, including 104, 271, and 173 patients in the younger, middle-aged, and elderly groups, respectively. Participants had a high-risk of bleeding and thromboembolism with a mean CHADS2 score of 3.1 ± 1.3, a mean CHA2DS2-VASc score of 4.7 ± 1.5, and a mean HAS-BLED score of 3.2 ± 1.0. Device success rates were 96.5% and anticoagulants discontinuation at the 45-day follow-up was achieved in 89.9%. In-hospital outcomes were not significantly different, but major bleeding events during the 45-day follow-up were significantly higher in the elderly group compared to the other groups (younger vs middle-aged vs elderly, 1.0% vs 3.7% vs 6.9%, respectively; P = 0.047) despite the same postoperative drug regimens. Conclusions The initial Japanese experience with LAAC demonstrated safety and efficacy; however, perioperative bleeding events were more common in the elderly and postoperative drug regimens must be tailored (OCEAN-LAAC [Optimized Catheter Valvular Intervention-Left Atrial Appendage Closure] registry; UMIN000038498).

Abstract
Background The indication for transcatheter aortic valve replacement (TAVR) for aortic stenosis (AS) significantly varies among physicians and institutions. Objectives This study aims to develop a set of appropriate use criteria for AS management to assist physicians in decision-making. Methods The RAND-modified Delphi panel method was used. A total of >250 common clinical scenarios were identified in terms of whether to perform the intervention for AS and the mode of intervention (surgical aortic valve replacement vs TAVR). Eleven nationally representative expert panelists independently rated the clinical scenario appropriateness on a scale of 1-9, as "appropriate" (7-9), "may be appropriate" (4-6), or "rarely appropriate" (1-3); the median score of the 11 experts was then assigned to an appropriate-use category. Results The panel identified 3 factors that were associated with a rarely appropriate rating in terms of performing the intervention: 1) limited life expectancy; 2) frailty; and 3) pseudo-severe AS on dobutamine stress echocardiography. Clinical scenarios that were deemed rarely appropriate for TAVR were also identified: 1) patients with low surgical risk and high TAVR procedural risk; 2) patients with coexistent severe primary mitral regurgitation or rheumatic mitral stenosis; and 3) bicuspid aortic valve that was not suitable for TAVR. Importantly, any TAVRs for patients who were older than 75 years of age were not rated as rarely appropriate. Conclusions These appropriate use criteria provide a practical guide for physicians regarding clinical situations commonly encountered in daily practice and elucidates scenarios deemed rarely appropriate that are clinical challenges for TAVR.

Abstract
BACKGROUND Global longitudinal strain (GLS) can predict cancer therapeutics-related cardiac dysfunction and guide initiation of cardioprotection (CPT). OBJECTIVES In this study, the authors sought to determine whether echocardiography GLS-guided CPT provides less cardiac dysfunction in survivors of potentially cardiotoxic chemotherapy, compared with usual care at 3 years. METHODS In this international multicenter prospective randomized controlled trial, patients were enrolled from 28 international sites. All patients treated with anthracyclines with another risk factor for heart failure were randomly allocated to GLS-guided (>12% relative reduction in GLS) or ejection fraction (EF)-guided (>10% absolute reduction of EF to <55%) CPT. The primary end point was the change in 3-dimensional (3D) EF (ΔEF) from baseline to 3 years. RESULTS Among 331 patients enrolled, 255 (77%, age 54 ± 12 years, 95% women) completed 3-year follow-up (123 in the EF-guided group and 132 in the GLS-guided group). Most had breast cancer (n = 236; 93%), and anthracycline followed by trastuzumab was the most common chemotherapy regimen (84%). Although 67 (26%) had hypertension and 32 (13%) had diabetes mellitus, left ventricular function was normal at baseline (EF: 59% ± 6%, GLS: 20.7% ± 2.3%). CPT was administered in 18 patients (14.6%) in the EF-guided group and 41 (31%) in the GLS-guided group (P = 0.03). Most patients showed recovery in EF and GLS after chemotherapy; 3-year ΔEF was -0.03% ± 7.9% in the EF-guided group and -0.02% ± 6.5% in the GLS-guided (P = 0.99) group; respective 3-year EFs were 58% ± 6% and 59% ± 5% (P = 0.06). At 3 years, 17 patients (5%) had cancer therapeutics-related cardiac dysfunction (11 in the EF-guided group and 6 in the GLS guided group; P = 0.16); 1 patient in each group was admitted for heart failure. CONCLUSIONS Among patients taking potentially cardiotoxic chemotherapy for cancer, the 3-year data showed improvement of LV dysfunction compared with 1 year, with no difference in ΔEF between GLS- and EF-guided CPT.

Abstract
Coronavirus disease 2019 (COVID-19) is endemic worldwide. Cardiovascular disease, particularly myocarditis, is one of the most common comorbidities in patients with COVID-19. However, heart failure due to COVID-19-triggered cardiomyopathy is not well understood. Additionally, "pseudo" heart failure symptoms have been reported in patients with a compensated condition, in which the heart works well enough that symptoms are unnoticeable or very easy to manage. Here, we report a case of heart failure due to cardiomyopathy in a patient with COVID-19 and postural orthostatic tachycardia syndrome after heart failure treatment. Learning objective. Postural orthostatic tachycardia syndrome (POTS) symptoms after coronavirus disease 2019 may be mistaken for heart failure symptoms; thus, it is essential to suspect POTS when symptoms such as shortness of breath and palpitations are noted upon standing, along with the relevant physical findings.

Abstract
Background No studies have demonstrated medium- or long-term skill retention of cardiac point-of-care ultrasound (POCUS) curriculum for medical student. Based on the American Society of Echocardiography (ASE) curriculum framework, we developed a blended-learning cardiac POCUS curriculum with competency evaluation. The objective of this study was to investigate the curriculum impact on image acquisition skill retention 8 weeks after initial training. Methods This study was a prospective, pre-post education intervention study for first- and second-year medical students, with blinded outcome assessment. The curriculum included a pre-training ASE online module and healthy volunteer hands-on training to obtain 5 views: parasternal long-axis (PLAX), parasternal short-axis (PSAX), apical 4-chamber (A4C), subcostal 4-chamber (S4C), and subcostal inferior vena cava (SIVC) views. Students took 5-view image acquisition skill tests at pre-, immediate post-, and 8-week post-training, using a healthy volunteer. Three blinded assessors rated the image quality using a validated 10-point maximum scoring system. Students used a hand-held ultrasound probe (Butterfly iQ). Results Fifty-four students completed hands-on training, and pre- and immediate post-training skill tests. Twenty-seven students completed 8-week post-training skill tests. Skill test score improvement between pre- and 8-week post-training was 2.11 points (95% CI, 1.22–3.00; effect size, 1.13). Conclusion The cardiac POCUS curriculum demonstrated medium-term skill retention. The curriculum was sufficient for S4C and SIVC skill retention, but inadequate for PLAX, PSAX, and A4C. Therefore, instructional design modifications or re-training for PLAX, PSAX, and A4C are needed to make the curriculum more effective for clinically relevant skill retention.

Abstract
BACKGROUND Although Doppler evaluation using a multiplanar method is recommended to assess the severity of aortic stenosis (AS) with transthoracic echocardiography, evidence on the diagnostic significance of a non-apical method is limited. This study aimed to compare the use of the apical with the use of the right parasternal view (RPV) method to evaluate AS severity and to examine the diagnostic significance of performing the RPV method in addition to the apical method during the evaluation. METHODS This retrospective observational study included 276 consecutive patients (mean age: 79 ± 10 years; women, 56%) with severe AS (aortic valve area [AVA] ≤1.0cm2 ). The severity of AS according to the apical method and that according to the RPV for all subjects were compared, and the significance of performing the RPV method in addition to the apical method was examined. Furthermore, we compared the concordance group, in which the apical and RPV methods indicated matching in severity, and the discordant group, in which the apical and RPV methods did not indicate matching severity. RESULTS Peak velocity (Vmax ), mean pressure gradient (MG) were significantly higher and the AVA, AVAi, and Doppler velocity index (DVI) were significantly smaller when the RPV was added to the apical view. Performing the RPV method in addition to the apical method significantly decreased the number of low PG AS cases (MG < 40 mmHg) from 69.9% to 65.0% and it increased the number of very severe AS cases (Vmax ≥ 5 m/s) from 8.7% to 14.5%. Deviation of Doppler angle was significantly greater in the discordant group compared to the concordant group (22.5 ± .6 vs. 31.8 ± 1.7, p < .001). CONCLUSIONS By performing the RPV method in addition to the apical method to determine AS severity, the diagnosis of AS to be resolved in approximately 10% of cases. These results suggest that AS severity may be underestimated by using the apical method alone.

Abstract
Aims Data on B‐type natriuretic peptide (BNP) levels and adverse outcomes in patients with moderate mixed aortic valve disease (MAVD), defined as moderate aortic stenosis (AS) and regurgitation (AR), are scarce. Therefore, this study investigated the impact of BNP on the clinical outcomes in such patients. Methods and results Clinical data from 81 patients (mean age, 74.1 ± 6.8 years; 50.6%, men) treated for moderate MAVD and left ventricular ejection fraction (LVEF) ≥ 50% during 2010–2018 were retrospectively analysed. Specific echocardiographic data of the study patients were LVEF of 57.8 ± 5.0%, aortic valve index of 0.64 ± 0.04 cm2/m2, peak aortic valve velocity of 3.38 ± 0.29 m/s, and AR vena contracta width of 4.2 ± 0.7 mm. The median BNP level was 61.4 pg/mL (interquartile range, 29.7–109.9). The primary endpoint was a composite of all‐cause death, heart failure hospitalization, and aortic valve replacement, and its cumulative incidence at 5 years was 57.7%. Multivariable analysis revealed that age (hazard ratio, 1.079; 95% confidence interval, 1.028–1.133; P = 0.002) and BNP levels (hazard ratio, 1.028; 95% confidence interval, 1.003–1.053; P = 0.027) were significantly related to the endpoint; specifically, BNP > 61.4 pg/mL had significantly higher incidence rates of the endpoint than those with a BNP ≤ 61.4 pg/mL (70.3% vs. 45.5% at 5 years; P = 0.018). Compared with patients with BNP ≤ 61.4 pg/mL, those with BNP > 61.4 pg/mL had significantly worse left ventricular global longitudinal strain (−17.1 ± 3.6% vs. −18.7 ± 2.6%; P = 0.029), along with higher left ventricular mass index (116.9 ± 27.8 g/m2 vs. 103.5 ± 19.7 g/m2; P = 0.014), relative wall thickness (0.45 ± 0.07 vs. 0.42 ± 0.05; P = 0.022), left atrial volume index (46.0 ± 28.4 mL/m2 vs. 31.4 ± 10.3 mL/m2; P = 0.003), pulmonary artery systolic pressure (32.6 ± 9.7 mmHg vs. 28.2 ± 4.7 mmHg; P = 0.011), and prevalence of moderate or greater tricuspid regurgitation (15.0% vs. 0.0%; P = 0.012). Conclusions Patients with moderate MAVD are at higher risk of unfavourable clinical outcomes, and age and BNP are independently related to the occurrence of adverse events. High BNP levels may reflect extravalvular cardiac damage in patients with moderate MAVD.

Abstract
BACKGROUND Older patients with aortic stenosis (AS) have a higher incidence of wild-type transthyretin cardiac amyloidosis (ATTR-CA). This study aimed to determine whether apical sparing of longitudinal strain (LS) could help diagnose ATTR-CA and provide useful prognostic information in symptomatic AS. METHODS We performed vendor-independent two-dimensional speckle-tracking analysis of regional and global left ventricular LS in 16 patients with ATTR-CA and 31 patients with non-obstructive hypertrophic cardiomyopathy to determine the best cutoff value of the apical sparing ratio (APSR) for diagnosing ATTR-CA. We then determined the prevalence in patients who had an APSR higher than the best cutoff value and investigated its prognostic value in 230 patients with symptomatic AS. To determine the natural history of symptomatic AS, patients who had aortic valve replacement were censored at the time of surgery. RESULTS The best cutoff value of APSR was 0.76. APSR ≥ 0.76 was observed in 108 patients with symptomatic AS (48%). The prevalence was not different among the four AS subgroups. During a median follow-up period of 5.7 months, 47 patients had cardiac events. Cox proportional hazards analysis revealed that neither APSR nor APSR ≥ 0.76 was significantly associated with future cardiac events. CONCLUSIONS Apical sparing was frequently observed in patients with symptomatic AS, and it was not a useful predictor of future adverse outcomes. Our results suggest that the underlying cause of apical sparing in AS may not be related to the presence of ATTR-CA.

Abstract
Heart failure (HF) is a challenging situation in healthcare worldwide. Secondary mitral regurgitation (SMR) is a common condition in HF patients with reduced ejection fraction (HFrEF) and tends to be increasingly associated with unfavorable clinical outcomes as the severity of SMR increases. It is worth noting that SMR can deteriorate dynamically under stress. Over the past three decades, the characteristics of dynamic SMR have been studied. Dynamic SMR contributes to the reduction in exercise capacity and adverse clinical outcomes. Current guidelines refer to the indication of transcatheter edge-to-edge repair (TEER) for significant SMR based on data from the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) trial if symptomatic despite optimal guideline-directed medical therapy (GDMT) and cardiac resynchronization therapy (CRT), but nonpharmacological treatment for dynamic SMR remains challenging. In HFrEF patients with LV dyssynchrony and dynamic SMR, CRT can improve LV dyssynchrony and subsequently attenuate SMR at rest and during exercise. Also, a recent study suggests that TEER with GDMT and CRT is more effective in symptomatic patients with HFrEF and dynamic SMR than GDMT and CRT alone. Further studies are needed to evaluate the safety and efficacy of nonpharmacological treatments for dynamic SMR. In this review, current evidence and challenges for the future of dynamic SMR are discussed.

Abstract
Our patient was a 60-year-old male with myocardial infarction. Urgent percutaneous coronary intervention was performed with intra-aortic balloon pump (IABP) support. Despite successful revascularization, the patient suffered from cardiogenic shock and heart failure. Secondary mitral regurgitation (MR) was mild and seemed unlikely to be the cause of heart failure. However, when IABP was temporarily stopped (IABP-OFF), secondary MR was aggravated; therefore, we decided to perform transcatheter mitral valve repair. Thereafter, only mild residual MR was observed after IABP removal, and hemodynamic stability was achieved. This case presents IABP-OFF test with echocardiography as a useful method to assess secondary MR.

Abstract
Edge-to-edge transcatheter mitral valve repair (TMVr) using MitraClip has been evolving rapidly in patients with severe mitral regurgitation (MR) at high surgical risk or having contraindications for surgery. Three-dimensional (3D) echocardiography plays an important role in the management of severe MR. In particular, 3D transesophageal echocardiography (TEE) imaging allows the evaluation of MV geometry and quantification of MR severity with dedicated software. Real-time 3D TEE is also commonly used to guide TMVr and facilitate the procedure. Further development of 3D echocardiography may help achieve safer and more beneficial results. The following article summarizes the current knowledge and the future perspectives of 3D TEE in TMVr.

Abstract
Background There is no evidence of hemodynamic performance during exercise in patients with aortic stenosis (AS) after transcatheter aortic valve implantation (TAVI). This study aimed to investigate the changes in kinematic hemodynamics during exercise and determine the impact of prosthesis-patient mismatch (PPM) on the hemodynamics of transcatheter heart valves using exercise stress echocardiography (ESE) in AS patients after TAVI. Methods and Results This study enrolled 77 consecutive patients (mean age 82 ± 5 years, 50.6% male) who underwent ESE 3–6 months after TAVI with a balloon-expandable valve. The effective orifice area index at rest was significantly correlated with the mean pressure gradient (PG) during exercise (p <0.001). The patients were divided into two groups according to the presence of PPM (PPM and non-PPM groups). During exercise, the patients with PPM had a higher left ventricular ejection fraction (74.6 ± 6.1% vs. 69.7 ± 9.6%, p = 0.048), a lower stroke volume index (47.2 ± 14.0 ml/m2 vs. 55.6 ± 14.5 ml/m2, p = 0.037), a significantly higher mean transvalvular PG (21.9 ± 9.1 mmHg vs. 12.2 ± 4.9 mmHg, p = 0.01) and an increased mean PG from rest to exercise (5.7 ± 3.5 mmHg vs. 2.3 ± 2.8 mmHg, p <0.001) compared with patients without PPM. Patients with PPM had a higher pulmonary artery systolic pressure (SPAP) during exercise (57.3 ± 13.8 mmHg vs. 49.7 ± 10.9 mmHg, p = 0.021) and a higher incidence of exercise-induced pulmonary hypertension (43.8 vs. 15.0%, p = 0.037) than patients without PPM. PPM was strongly associated with exercise-induced pulmonary hypertension (hazard ratio: 3.570, p = 0.013). Conclusions AS patients with PPM after TAVI showed a disproportionate increase in the transvalvular PG and SPAP during exercise, and PPM was associated with exercise-induced pulmonary hypertension.

Abstract
Heart failure (HF) is a burden in pandemic medicine resulting in high mortality and morbidity. Because acute HF is a life-threatening event, its diagnosis and choice of optimal treatment are important to improve outcomes. Furthermore, understanding the cause and hemodynamics of acute HF is important in selecting the optimal treatment for these patients. Echocardiography is widely used in daily clinical practice because of its non-invasive nature and excellent portability to understand cardiac function and hemodynamics. Echocardiography is highly recommended by guidelines in the practice of HF, but evidence is limited. In this review, I would like to share clinical value of echocardiography in the treatment of patients with acute HF and discuss the usefulness of echocardiography.

Abstract
BACKGROUND The MitraClip NT System was approved for marketing in Japan on October 31, 2017, and a prospective, multi-center, single-arm Post-Marketing use Surveillance (PMS) study was launched in 2018. This is the first report of the Japan PMS study with 1-year subject outcomes.Methods and Results:A total of 500 patients were registered between April 2018 and January 2019. Patients with symptomatic chronic moderate-to-severe (3+) or severe mitral regurgitation (MR; 4+), MR with a Society of Thoracic Surgery (STS) replacement score of ≥8%, or presence of 1 pre-defined risk factor were enrolled. Primary outcome measures included acute procedural success (APS), and rate of Single Leaflet Device Attachment (SLDA) at 30 days. The overall cohort was elderly (77.9±9.48 years) with functional MR etiology in 71.6% of the subjects. The majority of subjects were New York Heart Association (NYHA) class III/IV (68.9%), with mean STS replacement score of 11.95±9.66%. The APS rate was 91.13% and the 30-day SLDA rate was 1.21%. Durable MR reduction was achieved with 88.1% of subjects at MR ≤2+ at 1 year. Significant improvement in the functional capacity was observed, with 93% of subjects at NYHA class I/II at 1 year. CONCLUSIONS In the Japan PMS experience, the MitraClip procedure resulted in improvements in MR severity, with significantly improved functional outcomes. These results demonstrate safety and efficacy of MitraClip therapy in the eligible Japanese population.
