Outcomes of transcatheter edge-to-edge repair for atrial functional mitral regurgitation.

ABSTRACT:

Background

The prognostic benefits of transcatheter edge-to-edge repair (TEER) remain unclear in patients with atrial functional mitral regurgitation (AFMR).

Aims

We aimed to investigate the clinical outcomes of TEER for patients with AFMR.

Methods

We retrospectively classified functional mitral regurgitation (FMR) patients undergoing TEER into those with AFMR or ventricular FMR (VFMR). A residual MR ≤1+ at discharge was considered optimal mitral regurgitation (MR) reduction, and an elevated mean mitral valve pressure gradient (MPG) was defined as an MPG ≥5 mmHg at discharge. The primary outcome was a composite of all-cause mortality and hospitalisation due to heart failure within one year.

Results

Of 441 FMR patients, 125 patients were considered as having AFM
