Background: Information regarding the outcomes of transcatheter aortic valve replacement (TAVR) in men is limited. This study aimed to investigate short- to mid-term outcomes and prognostic predictors in this population. Method and Results: The data of 519 men were analyzed from 1,693 consecutive patients with symptomatic severe aortic stenosis who underwent TAVR at six hospitals between April 2010 and July 2020. The primary endpoint was all-cause mortality at 30 days after TAVR. The mean age and Society of Thoracic Surgeons (STS) score were 83.7 ± 5.9 years and 6.3 ± 4.7%, respectively. Overall, 23.5% of patients consumed alcohol with a frequency of > 1 drinks/week, and 12.1% consumed alcohol with a frequency of > 8 drinks/week, while 66.1% were former smokers and 4.2% were current smokers. Mortality at 30 days was 0.8%. During the median follow-up period of 448 days, the estimated survival rates at 1 year post-TAVR was 90.7 ± 1.4%. In multivariate analysis, the serum albumin level [hazard ratio (HR): 2.20, 95% confidence interval (CI):1.36–3.62, p = 0.001], atrial fibrillation (HR: 1.79, 95% CI: 1.13–2.82, p = 0.012), and STS score (HR: 1.33, 95% CI: 1.06–1.67, p = 0.015) were independently associated with all-cause mortality following TAVR. Adjusted hazard ratios of current smoking, heavy drinking, and presence of cancer were 1.05 (95% CI: 0.36–2.98),1.37 (95% CI: 0.75–2.48), and 1.13 (95% CI: 0.75–2.48), respectively. Conclusion: Our study demonstrated that serum albumin levels, atrial fibrillation, and STS score were independently associated with all-cause mortality following TAVR in men.

Objectives: We describe our method and results of mitral valve repair up to 20 years in a defined group of patients with mitral regurgitation caused by an extreme billowing and prolapsing valve. Methods: An extreme billowing and prolapsing valve was defined by the presence of excess tissue on both leaflets and prolapse of 2 or more of the 3 segments of each leaflet. Among 1344 consecutive patients who underwent mitral valve repair for degenerative mitral regurgitation between 1991 and 2012 at the Sakakibara Heart Institute, 73 patients met our definition of an extreme billowing and prolapsing valve. From these 73 patients, 67 patients who underwent mitral valve repair based on the surgical strategy we developed in July 1996 were enrolled in this study. Our strategy of mitral valve repair for extreme billowing and prolapsing valves consists of (1) volume reduction of the leaflets, (2) physiologic remodeling annuloplasty for long anterior leaflet, and (3) wide usage of artificial chordae. Results: Mean age of the patients was 46.6 ± 12.9 years. There were no hospital deaths and 6 late deaths in this series. Kaplan–Meier survival at 10 years was 96.8 ± 2.2%. There were 2 reoperations. Cumulative incidence rate of mitral valve reoperation and moderate or severe mitral regurgitation at 10 years was 1.8 ± 1.8% and 11.2 ± 4.0%. Number of artificial chordal replacement was associated with decreased risk of recurrent moderate mitral regurgitation (hazard ratio, 0.60; P = .03). Conclusions: Long-term echo follow-up demonstrates good results of mitral valve repair for extreme billowing and prolapsing valves using our strategy.

Background: Malignancy is common in older adults undergoing transcatheter aortic valve implantation (TAVI), and may affect prognosis. The present study aimed to examine whether active cancer affects all-cause mortality rates among patients undergoing TAVI. Methods: This retrospective study examined data from 1,114 consecutive patients treated between April 2010 and June 2019. Patients with life expectancy of

Background: The effect of increased arterial stiffness on mitral regurgitation (MR) is not clear. Using wave intensity (WI) analysis, which is useful for analyzing ventriculo-arterial interaction, we aimed to elucidate associations of increased arterial stiffness with left ventricular (LV) ejection performance and right ventricular systolic pressure (RVSP) in MR. Methods and Results: We noninvasively measured carotid arterial WI and stiffness parameter (β) in 98 patients with non-ischemic chronic MR before and after surgery, and 98 age-and-gender matched healthy subjects by ultrasonography. WI is defined as WI = (dP/dt)(dU/dt) [P: blood pressure, U: velocity, t: time]. The peak value of WI (W1) increases with LV peak dP/dt. The temporal WI index (Q-W1)st, which is the standardized interval between the Q wave of the ECG and W1, is a surrogate for preejection period. Ejection fraction (EF), left atrial volume index (LAVI), effective regurgitant orifice area (ERO), RVSP, and other echocardiographic data were also obtained. W1 was enhanced in the MR group before surgery compared with the normal group (10.7 ± 5.7 vs 8.5 ± 3.6 × 103 mmHg m/s3, p
