Why the study?
Catheter ablation outcomes for ventricular arrhythmia are unsatisfactory in nonischemic cardiomyopathy, and studies directly comparing outcomes between nonischemic and ischemic cardiomyopathy are limited.
Does catheter ablation for ventricular arrhythmia have different outcomes in non-ischemic cardiomyopathy compared to ischemic cardiomyopathy?

Lower success in NICM versus ICM warrants cautious expectations; confirms observational differences and extends call for NICM-specific trials.
Does catheter ablation for ventricular arrhythmia have different outcomes in non-ischemic cardiomyopathy compared to ischemic cardiomyopathy?
Catheter ablation for ventricular arrhythmia is associated with higher procedural failure and recurrence rates in patients with non-ischemic cardiomyopathy compared to those with ischemic cardiomyopathy.
