Comparative Efficacy and Safety of Extensive Electro-Anatomical Guided Pulsed Field Ablation Versus Radiofrequency Ablation in Persistent Atrial Fibrillation

This multicenter, randomized controlled trial aims to compare the efficacy and safety of extensive electro-anatomical guided pulsed field ablation (EXT-PFA) with traditional radiofrequency ablation (RF) in treating persistent atrial fibrillation (PeAF). The trial seeks to determine if EXT-PFA, which integrates anatomical and electrogram-guided strategies, can provide superior outcomes in terms of safety and effectiveness compared to the standard RF ablation approach.
