Clinical Outcomes in Patients With Dilated Cardiomyopathy and Ventricular Tachycardia.

Background: Recurrent ventricular tachycardia (VT) due to dilated cardiomyopathy (DCM) is difficult to treat, and long-term outcome data are limited.

Objectives: The aim of this study was to identify predictors of mortality or heart transplantation (HTx) and VT recurrence.

Methods: Consecutive patients with DCM accepted for radiofrequency catheter ablation (RFCA) of VT at 9 centers were prospectively enrolled and followed.
