Randomized Controlled Trial Comparative StudyLong-term clinical results of 2 different ablation strategies in patients with paroxysmal and persistent atrial fibrillation.
Data regarding the long-term efficacy of atrial fibrillation (AF) ablation are still lacking. ⋯ A long-term follow-up of AF ablation shows that short-term results cannot be considered permanent because AF recurrences are still present after the first year especially in patients who have had "PVI" strategy. PVI isolation plus LL is superior to the PVI strategy in maintaining SR without antiarrhythmic drugs after procedures 1 and 2 both in paroxysmal and persistent AF.
