BACKGROUND: The best periprocedural anticoagulation strategy at the time of pulmonary vein isolation (PVI) is not known. Most centers stop administering warfarin (Coumadin) and use bridging with heparin or enoxaparin. OBJECTIVE: The purpose of this study was to evaluate the efficacy and safety of PVI under therapeutic international normalized ratio (INR). METHODS: Between January 2005 and December 2008, PVI was performed in 3,052 patients with therapeutic INR (> or =1.8) at the time of ablation. All patients were evaluated for ischemic strokes and bleeding complications. RESULTS: Mean INR was 2.53 +/- 0.62. Only 3 (0.098%) patients had ischemic strokes. One patient had a hemorrhagic stroke on the third day postablation but recovered completely by 1-week follow-up. Bleeding complications occurred in 34 (1.11%) patients; most were minor (0.79%). Major hemorrhagic complications occurred in 10 (0.33%) patients (tamponade in 5, hematomas requiring intervention in 2, transfusion necessary in 3). CONCLUSION: In a large patient population, continuation of Coumadin at a therapeutic INR at the time of PVI without use of heparin or enoxaparin for bridging is a safe and efficacious periprocedural anticoagulation strategy. It is an acceptable and potentially better alternative to strategies that use bridging with heparin or enoxaparin.
