Higher premature atrial contraction burden after radiofrequency ablation vs. pulsed field or cryoballoon ablation in paroxysmal atrial fibrillation: a 3-year follow-up retrospective study.

ABSTRACT:

Background

Pulsed field ablation (PFA), a novel non-thermal energy source, has shown favorable 1-year data on the efficacy and safety profile in the treatment of paroxysmal atrial fibrillation (PAF). We sought to compare PFA, cryoballoon ablation (CBA), and radiofrequency ablation (RFA) in PAF treatment in a 3-year follow-up period.

Methods

Patients with PAF undergoing first-time catheter ablation by PFA, CBA, and RFA were retrospectively included. The procedure endpoint was pulmonary vein isolation (PVI). Patients were followed with 24 h ambulatory ECG monitoring at 1, 3, 6, and 12 months and every 6 months thereafter. The primary efficacy endpoint was freedom from any atrial tachyarrhythmia >30 s occurring after the 3-month blanking period.
