Arrhythmias Clinical Trials

Structural heart disease-related ventricular tachycardia (SHD-VT) is associated with substantial morbidity and mortality. Although catheter ablation, ICD therapy, antiarrhythmic drugs, and other treatment strategies are widely used, real-world evidence regarding patient characteristics, management patterns, long-term outcomes, and prognostic factors in China remains limited. This nationwide, multicenter, prospective observational registry aims to establish a comprehensive longitudinal database of patients with SHD-VT. Approximately 1,000 consecutive adult patients with documented sustained ventricular tachycardia, or clinically significant nonsustained ventricular tachycardia requiring treatment, in the presence of structural heart disease will be enrolled and followed prospectively. The study will collect detailed demographic characteristics, medical history, imaging findings, laboratory data, electrophysiological characteristics, treatment strategies, and follow-up outcomes without influencing routine clinical management. The primary effectiveness outcome is a composite of ventricular tachycardia recurrence or appropriate ICD therapy (when applicable), unplanned cardiovascular hospitalization, or all-cause death within 12 months. Long-term follow-up will continue to evaluate clinical outcomes, treatment safety, and prognostic factors. The registry is expected to provide high-quality real-world evidence to improve risk stratification, optimize clinical decision-making, and support future clinical research in patients with SHD-VT.
