Long-Term Registry Study of Catheter Ablation for Atrial Fibrillation and Ventricular Tachycardia in Chinese Patients

What this Trial Is About

Researchers are evaluating the long-term outcomes of catheter ablation for treating atrial fibrillation AF and ventricular tachycardia VT in Chinese patients. This prospective, non-randomized, multicenter observational registry study aims to systematically assess the effectiveness and safety of advanced radiofrequency ablation techniques. It focuses on redefining AF recurrence relationships and optimizing treatment strategies using AF burden, while also assessing novel technologies in VT treatment. The study includes two cohorts an AF cohort and a VT cohort. Catheter ablation procedures are performed using 3D mapping systems. For AF, pulmonary vein isolation is mandatory, with ablation strategies tailored by physicians. For VT, detailed mapping techniques identify critical regions for targeted ablation. The study observes patients undergoing first-time ablation with treatments delivered under general or local anesthesia. Participants will be monitored for freedom from atrial arrhythmia over 12 months following ablation, excluding a 3-month blanking period, and for composite outcomes including VT recurrence, cardiovascular hospitalization, or death during the same follow-up. Data collection involves clinical assessments, documentation of arrhythmia episodes, and safety monitoring. The registry provides important long-term safety and efficacy data over a minimum 12-month period, with follow-up visits to capture outcomes up to June 2032.
