Abstract
Although the concept of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) was derived from maze surgery, it is unclear if linear ablation in addition to circumferential pulmonary vein isolation (CPVI) reduces the recurrence rate in patients with paroxysmal AF. Therefore, we compared clinical outcomes of CPVI with additional linear ablations (Dallas lesion set) and CPVI in a prospective randomized controlled study among patients with paroxysmal AF.
