Concomitant Surgical Ablation in Paroxysmal vs Persistent Atrial Fibrillation During Mitral Surgery.

ABSTRACT:

Background

Despite prospective randomized evidence supporting concomitant treatment of atrial fibrillation (AF) during mitral valve (MV) surgery, variation in surgical management of AF remains. We assessed longitudinal outcomes after surgical treatment of persistent or paroxysmal AF during MV surgery in Medicare beneficiaries.

Methods

All Medicare beneficiaries with a diagnosis of AF undergoing MV surgery (2018-2020) were evaluated. Patients were stratified by no AF treatment, left atrial appendage obliteration (LAAO) alone, or surgical ablation and LAAO (SA+LAAO). Doubly robust risk adjustment and subgroup analysis by persistent or paroxysmal AF were performed.

Results

A total of 7517 patients with preoperative AF underwent MV surgery (32.1% no AF treatment, 23.1% LA
