Catheter ablation of electrical storm in patients with arrhythmogenic right ventricular cardiomyopathy.

Background: Therapeutic strategies for electrical storm (ES) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) are not well defined.

Objective: The purpose of this study was to report the acute and long-term results of ventricular tachycardia (VT) radiofrequency catheter ablation (RFCA) as a treatment of ES in patients with ARVC.

Methods: This multicenter study retrospectively enrolled 23 consecutive patients with ARVC (mean age 43.
