Novel Ablation Strategy for Treatment of Multiple Ventricular Tachycardias after Anterior Wall Myocardial Infarction: Isolation of the Entire Substrate

Background: Ventricular tachycardia (VT) may occur after anterior wall myocardial infarction. The best ablation strategy is unclear. We report about three patients in whom isolation oft the entire substrate was performed. Methods: Three patients (66±5 years, LVEF 29±14%) underwent catheter ablation for sustained VT after anterior wall myocardial infarction. All patients had recurrent ICD shocks (VT storm in two) despite amiodarone therapy. During electrophysiological-study, 4±2 VTs were induced including the clinical VT. 3D-mapping of the left ventricle (LV) was performed in SR (n=2) or during RV pacing (n=1) and revealed a low-voltage (
