Intracardiac Echocardiography-guided Versus Electroanatomical Mapping-guided Pulsed Field Ablation for Paroxysmal Atrial Fibrillation - the PFA-VISION Randomized Trial (Pulsed Field Ablation - Visualization and Imaging Strategies for Isolation Outcomes in Paroxysmal Atrial fibrillatioN)
This is a prospective, randomized clinical trial, which will be conducted in selected European centers. The objective is to compare two commonly used strategies to guide pulsed-field ablation (PFA) in patients with paroxysmal atrial fibrillation (AF). Patients with paroxysmal AF planned to undergo PFA will be randomized to intracardiac echocardiography (ICE)-guided or electroanatomical mapping-guided (OPAL HDx mapping system) ablation procedure. The primary efficacy endpoint will be freedom from atrial arrhythmia (AF, atrial flutter, atrial tachycardia) recurrence off antiarrhythmic drug therapy and without the need for electrical cardioversion or repeat ablation, with a follow-up duration of 12 months. The primary safety endpoint will be the incidence of predefined safety outcomes.
• History of paroxysmal AF.
• Scheduled to undergo AF catheter ablation with the FARAPULSE (Boston Scientific) PFA system.
