Study design of nationwide Japanese Catheter Ablation Registry: Protocol for a prospective, multicenter, open registry

Abstract

Background Catheter ablation has become a popular interventional treatment for cardiac tachyarrhythmias and the number has been on the rise year by year. However, little is known about its efficacy and safety in the real‐world settings. Method Japanese Catheter Ablation (J‐ AB ) Registry is a nationwide, multicenter, observational registry, performed by Japanese Heart Rhythm Society (JHRS), collaborated with National Cerebral and Cardiovascular Center. This study is a voluntary nationwide registry and data are collected prospectively using a Research Electronic Data Capture (REDCap) system. Detailed data collection including antiarrhythmic medication is also performed every September. The acute success rate at discharge and the complications associated with ablation procedure will be collected in all cases. Major bleeding events are defined according to Bleeding Academic Research Consortium criteria. Based on the provided information, the annual incidence and predictive factors for outcome will be investigated by the Event Assessment Committee. This registry started in August 2017 and the number of participating medical instructions will be more than 250 hospitals and the target procedure number will be 70 000 per year. We will also compare the results with other registries in foreign countries. Result The results of this study are currently under investigation. Conclusion The J‐ AB registry will provide a real‐world data regarding the acute success and complications in Japan, focusing on various types of catheter ablation for cardiac arrhythmias.

Registro Español de Ablación con Catéter. XIX Informe Oficial de la Asociación del Ritmo Cardiaco de la Sociedad Española de Cardiología (2019)

“…El Swedish Catheter Ablation Registry 24 ha ofrecido recientemente una información integral y amplia sobre la mayoría de procedimientos de 10 años (2006-2015), aunque faltan sustratos como las taquicardias macrorreentrantes o no se diferencian las diferentes formas de TV como en el nuestro. Finalmente, en Japón se está incluyendo a pacientes en un registro similar al español, aunque está aún en proyecto 25 .…”

The Japanese Catheter Ablation Registry (J‐AB): A prospective nationwide multicenter registry in Japan. Annual report in 2018

“…However, the details of the procedures (type of targeted arrhythmias, success rate or complications during the ablation procedure, and current strategy, etc) have been lacking. Accordingly, the J‐AB registry was conducted to clarify the efficacy and safety in the real‐world setting 4 . This study was started in August 2017 and was expected to initially collect data from around 250 hospitals, but the number of participating medical institutions increased to over 350 hospitals by the end of 2018.…”

“…This nationwide registry was a voluntary one and started in August 2017. The method of this registry has been previously reported elsewhere 4 . In brief, the study consisted of patients who were treated with any type of catheter ablation for any type of arrhythmia.…”

Current Status of Catheter Ablation for Atrial Fibrillation in Japan

“…The Japanese Catheter Ablation (J-AB) registry is an ongoing, nationwide prospective registry, which collects data on all cases performed in Japan. 3,18) The incidence of repeated AF ablation has not been reported from the J-AB registry. In contrast to these registries, our findings were from patient-based health check-ups and a claims database.…”
