The benefit of novel ICD programming in reducing inappropriate ICD therapy and mortality was demonstrated in Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate Therapy (MADIT-RIT) [14]. Catheter ablation has been considered a plausible curative therapy for VT prevention, especially in patients with VT episodes [15]. The Substrate Mapping and Ablation in Sinus Rhythm to Halt Ventricular Tachycardia (SMASH-VT) and the Ventricular Tachycardia Ablation in Coronary Heart Disease (VTACH) found that prophylactic catheter ablation reduces the incidence of appropriate ICD therapy in patients who had undergone ICD implantation as a means of secondary prevention and had a history of myocardial infarction (MI) [16,17]. It was also shown in a small retrospective study that prophylactic catheter ablation for induced VT reduced the incidence of appropriate ICD therapy in primary prevention post-MI patients [18].
