Atrial Fibrillation Ablation without Interruption of Anticoagulation

Figure 1

Complications of radiofrequency catheter ablation of atrial fibrillation in 6,454 patients referred to our institution between 2002 and 2009. TIA = transient ischemic attack; 8-mm = 8-mm nonirrigated ablation catheter; OIC = open irrigated ablation catheter; off/on Coumadin = periprocedural discontinuation/maintenance of therapeutic oral anticoagulant therapy with warfarin (Coumadin). P from multiple comparison between OIC on Coumadin and 8-mm and OIC off Coumadin: data from Di Biase et al. [13].
