Comparison of Catheter Ablation in Patients with Paroxysmal Non-valvular Atrial Fibrillation and Heart Failure with Preserved Ejection Fraction.

ABSTRACT: Background: The efficacy of radiofrequency ablation (RFA) in patients with atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) has been established, but the efficacy and safety of cryoballoon ablation (CBA) and pulsed field ablation (PFA) remain unclear. Methods: This retrospective cohort study included 223 patients with paroxysmal non-valvular AF and HFpEF who underwent their first AF ablation between January 2017 and December 2021 and were divided into RFA (n = 77), CBA (n = 127), and PFA (n = 19) groups. Results: After a mean follow-up of 11.2 ± 1.8 months, no significant differences were observed in the rates of AF recurrence among the groups (P = 0.964). Both RFA and PFA were associated with a reduction in left atrial diamete
