NON-PULMONARY VEIN TRIGGER ABLATION IMPROVES THE SINGLE-PROCEDURE SUCCESS RATE OF CATHETER ABLATION IN PERSISTENT ATRIAL FIBRILLATION: RESULTS FROM A LARGE PROSPECTIVE MULTICENTRE EXPERIENCE

Catheter ablation of persistent atrial fibrillation (PerAF) has a lower success rate when compared to paroxysmal AF. It is still debated in the literature whether pulmonary vein antrum isolation (PVAI) is sufficient to achieve long-term freedom from atrial tachyarrhythmias in PerAF patients.
