Of these patients, 72.0% of them were classified as NYHA functional class III/IV, and all of them had persistent AF. All patients underwent mitral valve (MV) repair, and 52 (63.4%) received concomitant surgical ablation (SA). Patients were followed up for 26.1±27.6 months, and postoperative mitral regurgitation (MR) was assessed by echocardiography.<h4>Results</h4>There was no in-hospital mortality. The overall 1-year and 3-year survival rates were 97.5% and 92.9%, respectively, and 96.1% of patients recovered toAnnals of translational medicine1420https://www.ebi.ac.uk/biostudies/studies/S-EPMC7723636biostudies-literatureMitral valve repair and surgical ablation for atrial functional mitral regurgitation.PMC7723636Ding WYang ZLv MChen JWang CHong TLin YWang YWei LZhu SfalseMitral valve repair and surgical ablation for atrial functional mitral regurgitation.<h4>Background</h4>This observational study aimed to share our experience in the surgical management of atrial functional mitral regurgitation (AFMR).<h4>Methods</h4>We retrospectively identified 82 AFMR patients (63.6±7.7 years) from June 2008 to November 2018 at our institution.
