Complex Arrhythmia Registry（CAR）： Long-term Outcomes of Catheter Ablation for Atrial Fibrillation or Ventricular Tachycardia： A Multicenter， Prospective Cohort Study
This is a prospective, non-randomized, multicenter observational registry study designed to systematically evaluate the long-term efficacy and safety of catheter ablation for treating atrial fibrillation (AF) and ventricular tachycardia (VT) in Chinese patients.
⁃ Age ≥ 18 years.
• Diagnosed with atrial fibrillation (AF), including paroxysmal AF (PAF) and persistent AF (PsAF).
• Scheduled to undergo first-time catheter ablation for AF.
• Procedure to be performed using a 3D mapping system.
• Provision of signed written informed consent for study participation and willingness and ability to comply with all protocol-required follow-up assessments.
⁃ Age ≥ 18 years.
• Diagnosed with ventricular tachycardia (VT) associated with underlying structural heart disease, including:
• Ischemic heart disease (e.g., prior MI, coronary artery disease).
• Non-ischemic cardiomyopathy (e.g., dilated cardiomyopathy (DCM), arrhythmogenic right ventricular cardiomyopathy (ARVC), hypertrophic cardiomyopathy (HCM)).
• Scheduled to undergo first-time catheter ablation for VT.
• Procedure to be performed using a 3D mapping system.
• Provision of signed written informed consent for study participation and willingness and ability to comply with all protocol-required follow-up assessments.
