Transcatheter Versus Standard Surgical Mitral Valve Operation for Secondary Mitral Regurgitation

概要

The mechanical intervention is treating secondary mitral regurgitation (SMR) which may be performed using the standard open surgical approach or transcatheter edge to edge repair (TEER). The key question of this study is to establish the difference in left ventricular reverse remodeling after adjustment for death, as assessed by means of the left ventricular end-systolic dimension(LVESD), all-cause and cause-specific (cardiac vs noncardiac) mortality in patients who received the TEER vs the standard surgical procedure for SMR.
