Impact of Atrial Fibrillation in Patients With Severe Mitral Regurgitation Undergoing Transcatheter Edge-to-Edge Repair.

ABSTRACT:

Background

Atrial fibrillation (AF) and mitral regurgitation (MR) are closely linked, and one may worsen the other. We investigated the impact of baseline AF in patients with MR undergoing transcatheter edge-to-edge repair.

Methods

One-hundred-fifty-six consecutive patients with symptomatic heart failure (HF) undergoing mitral valve transcatheter edge-to-edge repair for severe MR were studied. The primary end point was the composite outcome of death or HF hospitalization. Transthoracic echocardiograms were performed at baseline and follow-up.

Results

Mean age was 80.8±8.8 years and 82 (52.6%) patients were female. MR cause was primary in 69 (44.2%) and secondary in 87 (55.8%) patients. AF or atrial flutter was present in 59 (37.8%) patients at baseline. Mitral valve t
