Scar Homogenization Versus Limited-Substrate Ablation in Patients With  Nonischemic Cardiomyopathy and Ventricular Tachycardia

BackgroundScar homogenization improves long-term ventricular arrhythmia –free survival compared with standard limited-substrate ablation in patients with post-infarction ventricular tachycardia (VT). Whether such benefit extends to patients with nonischemic cardiomyopathy and scar-related VT is unclear.ObjectivesThe aim of this study was to assess the long-term efficacy of an endoepicardial scar homogenization approach compared with standard ablation in this population.MethodsConsecutive patients with dilated nonischemic cardiomyopathy (n  = 93), scar-related VTs, and evidence of low-voltage regions on the basis of pre-defined criteria on electroanatomic mapping (i.e., bipolar voltage
