Abstract
Catheter ablation of ventricular tachycardia (VT) has improved arrhythmia-free survival in patients with multiple VT episodes refractory to antiarrhythmic drugs. Recent studies have evaluated the role of early intervention with catheter ablation in patients experiencing a single episode of life-threatening ventricular arrhythmias and undergoing secondary prevention defibrillator implantation. Such "primary VT ablation" strategy has proven effective in reducing the VT recurrence rate compared with standard medical therapy (no antiarrhythmic drug). This article summarizes the evidence on primary VT ablation and discusses its clinical indications and outcomes compared with standard catheter ablation of drug-refractory recurrent VT (ie, secondary VT ablation).
