Empirical Anatomy-Based Ablation vs Emphasize Map-Guided Substrate Ablation in Persistent Atrial Fibrillation : (COMPASS-AF)

This study is aimed to compare the clinical efficacy of two different catheter ablation strategies in patients with persistent atrial fibrillation. Participants will be randomized 1:1 into either the Anatomy-based group or the Emphasize map-guided group * Anatomy-based group : Pulmonary vein isolation (PVI) using pulsed-field ablation (PFA) with a single-shot multielectrode catheter. * Emphasize map-guided group : PVI using radiofrequency (RF) ablation followed by additional EnSite X-guided pathologic substrate modification. Participants will be followed for 1 year to compare the incidence of any atrial tachyarrhythmia and other clinical parameters between the two groups.
