Risk of acute pericarditis after pulsed-field ablation pulmonary vein isolation.

ABSTRACT:

Background

Postablation pericarditis (PAP) can occur after pulmonary vein isolation (PVI) using radiofrequency ablation (RFA). Pulsed-field ablation (PFA) PAP is anticipated to be lower based on its nonthermal nature and initial studies.

Objective

We aimed to evaluate the incidence of PAP after PFA and compare this with rates of RFA PAP.

Methods

We prospectively identified cases of PAP in 322 patients who underwent PFA PVI ablation between April 2024 and December 2024 and 1750 patients who underwent RFA PVI between January 2022 and December 2024. Logistic regression was used to assess factors associated with PAP.

Results

Acute pericarditis occurred in 14 PFA patients and 60 RFA patients (4.3% vs 3.4%, P = .41). Median time to PAP presentation was 4 days
