Thirty-day and one-year outcomes following transcatheter mitral valve edge-to-edge repair versus transapical mitral valve replacement in patients with left ventricular dysfunction.

ABSTRACT:

Background

A comparison of 30-day and 1-year clinical outcomes in patients with pre-existing left ventricular (LV) dysfunction undergoing transcatheter mitral valve edge-to-edge repair (TEER) or transcatheter transapical mitral valve replacement (TMVR) has not previously been reported.

Aims

We aimed to compare 30-day and 1-year rates of all-cause and cardiovascular mortality as well as rehospitalisation for heart failure (HFH).

Methods

All patients with severe (≥3+) symptomatic mitral regurgitation (MR) and an LV ejection fraction ≤50% who underwent TEER or TMVR over a 5-year period were evaluated.

Results

Ninety-six patients (50 TEER, age 80±9 years, 70% secondary MR and 46 TMVR, age 72±9 years, 91% secondary MR) were studied. Baseline demographic and transtho
