Residual or recurrent mitral regurgitation predicts mortality following transcatheter edge-to-edge mitral valve repair.

ABSTRACT:

Objective

Although regurgitant mitral valves can be repaired through surgical or transcatheter approaches, contemporary comparative outcomes are limited with the impact of residual and recurrent mitral regurgitation (MR) on clinical outcomes being poorly defined. We hypothesized that moderate (2+) or greater residual or recurrent (RR) MR-regardless of type of repair-predicts worse clinical outcomes.

Methods

Our institutional experience of 660 consecutive patients undergoing mitral valve repair (2015-2021) consisting of 393 surgical mitral valve repair (SMVr) and 267 transcatheter edge-to-edge mitral valve repair (TEER) was studied. The echocardiographic impact of RRMR (2+) following both SMVr and TEER on death and reintervention was evaluated.
