Electrical storm originating from a left ventricular epicardial scar in a patient with completely normal endocardial voltage

Abstract

We report a patient with non-ischemic dilated cardiomyopathy presenting with an electrical storm because of a poorly tolerated monomorphic ventricular tachycardia. Electroanatomical mapping revealed a scar restricted to the epicardium, whereas the endocardial voltage map was completely normal. Epicardial catheter ablation based on substrate mapping and limited pace and entrainment mapping eliminated the tachycardia.
