Myocardial dissection following successful chemical ablation of ventricular tachycardia

Abstract

We describe a case of fatal myocardial rupture and tamponade following a successful transcoronary chemical ablation of incessant ventricular tachycardia. Pathological examination showed a subepicardial dissection of the heart at the ablation site with fibrous and fatty degeneration of the myocardium. The present report calls for caution, underlying a possible lethal complication of ethanol ablation which has not been described before.
