Key result
Shinshu-AB Registry evaluates real-world outcomes and complications of catheter ablation for arrhythmias.
Why the study?
The impact of catheter ablation strategies has not been thoroughly investigated, particularly in regions like Nagano Prefecture where geographical factors and lack of cardiac surgeons at some hospitals may limit their application.
What are the real-world outcomes and complications of catheter ablation for various arrhythmias in Nagano Prefecture?
Observational (n=2,500)
Yes
What are the real-world outcomes and complications of catheter ablation for various arrhythmias in Nagano Prefecture?
The Shinshu-AB Registry is designed to provide real-world data on the efficacy and safety of catheter ablation strategies for various arrhythmias in a geographically large region with limited surgical backup.

May inform Japanese ablation practices; leaves open generalizability pending randomized data.
Background: Catheter ablation (CA) is a well-established therapy for arrhythmia, but the impact of CA strategies has not been thoroughly investigated. Nagano Prefecture comprises a large geographical area and some hospitals do not have cardiac surgeons, thus limiting the application of CA strategies. The aim of this study was to investigate the detailed strategies for CA in Nagano Prefecture and to clarify their efficacy and safety. Methods and Results: The Shinshu Catheter Ablation (Shinshu-AB) Registry is a multicenter prospective observational registry. Patients treated with CA for any type of arrhythmia are included. Data on the target arrhythmia(s), CA strategy, outcomes, and complications were collected and analyzed at Shinshu University Hospital. The study was approved by the institutional review boards of all investigational sites and registered in the UMIN Clinical Trials Registry (UMIN-55562). Primary endpoints were the composite incidence of arrhythmia recurrence, procedure-related adverse events, and cardiovascular events. The secondary endpoints were acute success, chronic success for >12 months, and all-cause death. Conclusions: The Shinshu-AB Registry provides real-world data from the Nagano Prefecture on the outcomes and complications of CA for various types of arrhythmias.
