Concomitant ablation for non-paroxysmal atrial fibrillation: combined energy versus cryoablation alone.

ABSTRACT:

Background

Surgical ablation of atrial fibrillation has been the most efficient treatment for atrial fibrillation (AF). Combined energy (CE) ablation and cryoablation alone (CA) are the most common energy modes used for ablation, however, comparative data is lacking.

Objectives

To compare the efficacy of CE ablation with CA in the setting of concomitant biatrial ablation for non-paroxysmal AF.

Methods

A retrospective analysis of 453 patients with non-paroxysmal AF undergone concomitant biatrial ablation from November 2007 to December 2022 during elective cardiac surgery using either combined bipolar radiofrequency with cryoenergy or cryoenergy alone was performed. Propensity score matching was conducted to balance the covariates in the groups.
