The Japanese Catheter Ablation Registry (J-AB): Annual report in 2021.

Abstract

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 2021, we have collected a total of 89 609 procedures (mean age of 66.1 years and 65.9% male) from 506 participant hospitals. Detailed data are shown in Figures and Tables.
