title: Idiopathic epicardial ventricular tachycardia with origin remote from vascular structures.
abstract: We report a case of a patient with idiopathic left ventricular tachycardia (VT) successfully ablated from the epicardial aspect of the left ventricle, after a previous failed endocardial ablation. The VT appeared to be catecholamine sensitive. An excellent epicardial pacemap was found in the midlateral region of the left ventricle, remote from vascular structures. Following ablation, the patient discontinued antiarrhythmic drug use and has not experienced any recurrence of VT for more than 2 1/2 years.
