Preoperative Risk Factors for Acute Postoperative Atrial Fibrillation in Patients Undergoing Mitral Valve Repair for Degenerative Mitral Regurgitation: Insights Into Cardiac Geometry.

ABSTRACT:

Background

Postoperative atrial fibrillation (POAF) commonly occurs following surgical repair of degenerative mitral regurgitation (DMR) and is associated with unfavorable outcomes. This study aimed to identify preoperative risk factors for acute POAF in patients undergoing mitral valve repair for DMR, with a specific focus on the role of preoperative echocardiography.

Methods

A retrospective study was conducted involving 1127 DMR patients who underwent mitral valve repair between 2017 and 2022. The primary endpoint was the occurrence of acute POAF within 30 days after surgery. Univariate and multivariate logistic regression analyses were performed to identify risk factors for POAF. Additionally, subgroup analyses were conducted to evaluate the predictive value of preoperati
