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
