The Effectiveness of Catheter Ablation in the Management of Ventricular Tachycardia in Comparison With Antiarrhythmic Drugs in Patients With Structural Heart Disease: A Meta-Analysis.

The aim of this meta-analysis is to compare the safety and efficacy of catheter ablation versus antiarrhythmic drugs (AADs) in the management of ventricular tachycardia (VT) in patients with structural heart diseases. Two independent investigators searched electronic databases including PubMed, Cochrane, and Excerpta Medica database (EMBASE) using keyword combinations (Medical Subject Headings (MeSH) terms and free terms) such as "catheter ablation," "ventricular tachycardia," "escalation," and "antiarrhythmic drugs" from inception to November 30, 2022. The primary efficacy outcomes included recurrence of VT at follow-up, all-cause mortality, and cardiovascular mortality.
