Instant termination as a novel indicator for prognosis of persistent atrial fibrillation during cryoballoon ablation: a propensity score-matched analysis.

ABSTRACT:

Background

Instant atrial fibrillation termination (AFT) during radiofrequency ablation has been suggested as a predictor of prognosis in persistent atrial fibrillation (AF). However, its role in cryoballoon ablation remains unclear. This study investigated the association between AFT and recurrent atrial tachyarrhythmia in patients with persistent AF undergoing cryoballoon ablation.

Methods

Patients with non-valvular, drug-resistant, persistent AF who underwent cryoballoon ablation between January 2021 and June 2023 were included and categorized based on the presence or absence of AFT. Propensity score matching (PSM) was applied to eliminate covariate imbalances. Baseline characteristics, procedural details, and clinical outcomes were compared between the groups.
