Outcomes of Mitral Valve Surgery for Atrial Functional Mitral Regurgitation vs Ventricular Functional Mitral Regurgitation.

ABSTRACT:

Objectives

Atrial functional mitral regurgitation (AFMR) is a unique category of functional mitral regurgitation (FMR), and surgical outcomes compared to traditional ventricular FMR (VFMR) are limited. This study compared long-term outcomes of mitral valve surgery (MVS) for patients with AFMR and VFMR, including AFMR subtypes.

Methods

Patients who underwent MVS for non-degenerative, moderate, or greater MR from 2000 to 2022 at our institution were included. AFMR and VFMR groups were 1:1 propensity matched based on 14 preoperative variables. Primary outcomes were cumulative survival and MVS failure, which was defined as recurrent moderate or greater MR or reoperation. Secondary analysis stratified patients by AFMR subtype: atrial fibrillation (AF) only, heart failure with pre
