Echocardiographic Predictors of Suboptimal Transcatheter Mitral Valve Repair in Patients With Secondary Mitral Regurgitation.

Background: Residual mitral regurgitation (MR) following mitral valve transcatheter edge-to-edge repair (TEER) is associated with worse outcomes. This study sought to identify echocardiographic predictors of suboptimal residual MR after TEER in patients with secondary MR.

Methods: In this retrospective single-center study, we identified all patients with secondary MR who underwent TEER between 2016 and 2021.

Change in Invasively Measured Mean Pulmonary Artery Pressure After Transcatheter Mitral Valve Repair Is Associated With Heart Failure Readmission.

Background: Pre-existing pulmonary hypertension is associated with poor outcomes after transcatheter mitral valve repair (TMVr) for mitral regurgitation (MR). However, the impact of an immediate change in mean pulmonary artery pressure (ΔmPAP) following TMVr on outcomes is unknown.

Methods: Patients who underwent TMVr from December 2015 to February 18, 2020 at our institution for symptomatic 3-4+ MR and who had invasive hemodynamics measured immediately pre- and post-TMVR were included.
