Atrial Fibrillation Ablation without Interruption of Anticoagulation

Figure 2

Benefits of atrial fibrillation ablation without interruption of oral anticoagulation. TIA = transient ischemic attack; 8-mm off Coumadin (referent group) = 8-mm nonirrigated ablation catheter with periprocedural discontinuation of therapeutic oral anticoagulant therapy with warfarin (Coumadin); OIC off Coumadin = open irrigated ablation catheter with periprocedural discontinuation of therapeutic oral anticoagulant therapy with Coumadin; OIC on Coumadin = open irrigated ablation catheter with periprocedural maintenance of therapeutic oral anticoagulant therapy with Coumadin: data from Di Biase et al. [13].
