Transcatheter Mitral Valve Replacement or Repair for Secondary Mitral Regurgitation: A Propensity Score-Matched Analysis

Abstract

In this PS-matched comparison between TMVR and M-TEER in patients with severe SMR, TMVR was associated with superior reduction of MR and superior symptomatic improvement. While post-procedural mortality tended to be higher after TMVR, no significant differences in mortality were found beyond 30 days.
