BACKGROUND
Direct comparisons of combined (C-ABL) and non-combined (NC-ABL)
endo-epicardial ventricular tachycardia (VT) ablation outcomes are
scarce. We aimed to investigate the long-term clinical efficacy and
safety of these 2 strategies in ischemic heart disease (IHD) and
nonischemic cardiomyopathy (NICM) patients.
