The Japanese Catheter Ablation Registry (J‐AB): Annual report in 2019

The Japanese Catheter Ablation (J‐AB) registry, started in August 2017, is a voluntary, nationwide, multicenter, prospective, observational registry, performed by the Japanese Heart Rhythm Society (JHRS) in collaboration with the National Cerebral and Cardiovascular Center using a Research Electronic Data Capture system. The purpose of this registry is to collect the details of target arrhythmias, the ablation procedures, including the type of target arrhythmias, outcomes, and acute complications in the real‐world settings. During the year of 2019, we have collected a total of 80 795 procedures (mean age of 65.2 years and 66.4% male) from 425 participant hospitals. Detailed data are shown in Figures and Tables. J‐AB is a prospective nationwide multicenter registry designed to collect clinical variables, successful ablation rate and sort‐term outcome, aiming to register all catheter ablation cases performed in Japan. We successfully collected 80 795 procedures during the year of 2019.
