title: [Advancement and current indication of catheter ablation for atrial fibrillation].
abstract: New era of catheter ablation (CA) therapy for atrial fibrillation (AF) was opened by the new insight that the pulmonary vein (PV) might play a role of triggering AF. For paroxysmal AF, extensive PV isolation (PVI) is highly effective with superiority to medical treatment shown. For persistent AF with its persistent mechanism unknown, challenging stepwise ablation comprised of PVI and substrate ablation has been widely performed due to its acceptable efficacy in spite of prolonged procedure time with extensive ablation and requirement of repetitive sessions. The outcome of CABANA Trial concerning the effect of CA on improvement of patient's QOL, survival and prevention of cerebral infarction and other cardiovascular events are awaited to optimize its method and indication.
