Surgical Strategy for Atrial Functional Mitral Regurgitation With Atrial Fibrillation.

ABSTRACT:

Background

Atrial functional mitral regurgitation (AFMR) combined with atrial fibrillation (AF) has become a significant clinical challenge. This study evaluates surgical treatment strategies based on the degree of MR and rhythm control therapy for patients with AFMR and AF.

Methods

This retrospective study included 145 patients with AF and MR from January 2017 to January 2023. Patients were grouped as follows: moderate atrial regurgitation (n=33), severe atrial regurgitation (SAR, n=56), and severe primary regurgitation (SPR, n=56). The group with moderate atrial regurgitation underwent thoracoscopic AF procedure with a unilateral approach, and the SAR and SPR groups received mitral valvuloplasty plus the Cox-Maze IV procedure.
