Nationwide Japanese Registry Tracking Outcomes and Safety of Catheter Ablation for Heart Rhythm Disorders

What this Trial Is About

The Japanese Catheter Ablation J-AB Registry is a nationwide observational study conducted by the Japanese Heart Rhythm Society in collaboration with the National Cerebral and Cardiovascular Center. It aims to track and describe the progress and activity of catheter ablation treatments for cardiac arrhythmias across Japan. The study collects data to provide reliable information on treatment types and available facilities in arrhythmia units nationwide. Data are collected prospectively using an electronic system, including detailed information on antiarrhythmic medications gathered annually each September. The registry records the success rate of ablation procedures at hospital discharge and monitors complications, including major bleeding events. An event assessment committee evaluates the annual incidence and predictive factors related to outcomes. Participants contribute data on their catheter ablation treatment, with researchers recording outcomes such as arrhythmia recurrence up to one week after hospital discharge. Additional follow-up tracks deaths and treatment-related complications up to three months. The study is ongoing, with data collection supporting continuous monitoring of catheter ablation practices and patient outcomes in Japan.
