Incidence and predictors of pericardial effusion as an early complication of catheter ablation for atrial fibrillation: The Japanese Catheter Ablation Registry of Atrial Fibrillation (J-CARAF)

Critical PE occurred in 1% of AF ablation procedures in Japan. Our results suggest that 3-D imaging system use independently reduces the frequency of PE. DOACs in the setting of catheter ablation of AF seemed to be non-inferior to warfarin in terms of safety and effectiveness.
