ABSTRACT

Radiofrequency catheter ablation is accepted as an effective and curative therapy for idiopathic ventricular tachy- cardia (IVT). Although endocardial radiofrequency (RF) ablation is the common approach for ablation of IVTs, rare patients have been reported in whom ventricular tachycardia (VT) could not be ablated from endocardium due to an epicardial origin of the tachycardia. We, herein, present a case of IVT originating from the great cardiac vein that was successfully ablated within the coronary venous system.
