Alcohol Ablation of Ventricular Tachycardia. Ventricular tachycardia that is refractory to medical management has been treated with surgical resection, catheter ablation, and antitachycardia pacemaker. In this case report we describe the use of transcoronary alcohol ablation to treat a patient's ventricular tachycardia. This is accomplished by using ethanol to destroy the site of origin or pathways used in ventricular tachycardia.
