Abstract
A 36-year-old man with frequent episodes of ventricular tachycardia (VT) was referred to our hospital for ablation due to the suspicion of sarcoidosis and arrhythmogenic right ventricular cardiomyopathy in cardiac magnetic resonance imaging. After implantable cardioverter-defibrillator implantation, the patient presented with VT storm, without any endocardial scar and with an extensive epicardial scar in voltage mapping. Consequently, he underwent epicardial VT ablation. (Iranian Heart Journal 2021; 22(1): 112-116)
