Catheter Ablation of Long Standing Persistent Atrial Fibrillation: Lessons Learned

Over the past decade catheter ablation of atrial fibrillation has evolved from being a novel unproven procedure to being an important treatment option for patients with symptomatic atrial fibrillation. According to the 2012 HRS/ECAS/ECHRA Consensus document on Catheter Ablation of Atrial Fibrillation (AF), AF ablation is an appropriate treatment option for patients with symptomatic AF, particularly if they have failed one or more trials of antiarrhythmic drug therapy [1-4]. While much has been learned about the optimal technique and outcomes for catheter ablation of paroxysmal AF; catheter ablation of AF in patients with long standing persistent AF remains in its infancy. Very few studies have been published which report the technique and outcomes of catheter ablation in patients who have long standing persistent atrial fibrillation, defined as continuous AF for 12 months or longer.
