Background: The purpose of this study was to provide precise data on the current status of catheter ablation for atrial fibrillation (AF) in Japan. Methods and Results: The Japanese Heart Rhythm Society requested that members retrospectively register data for AF ablation performed in September 2011, March 2012, and September 2012. A total of 165 centers submitted data for 3,373 patients (age, 62±11 years; male, 76.1%; paroxysmal AF, 64.4%). Pulmonary vein isolation (PVI) and additional ablation were performed in 97.5% and 77.4% of patients, respectively. 3-D mapping systems and irrigated-tip catheters were used in 94.8% and 87.7% of the patients, respectively. Although the mean CHADS2 score was 1.0±1.0, the majority received oral anticoagulant (OAC) during and following the procedure (69.8% and 97%, respectively). Vitamin K antagonist (VKA) prescription, however, decreased (1st vs. 3rd survey, during and following the procedure, 59.3% vs. 47.8% and 81.7% vs. 55.2%, respectively, P<0.0001, both) and that of new OAC (NOAC) increased drastically (9.6% vs. 24.2% and 15.8% vs. 42.1%, respectively, P<0.0001). Early complications were reported in 4.5% of the patients, but no instance of early death was reported. Conclusions: In addition to PVI, additional ablation procedures are also performed very frequently. Although the mean CHADS2 score was low, peri-procedural OAC therapy was commonly performed, and NOAC drastically superseded VKA.
