Successful catheter ablation of left ventricular epicardial tachycardia originating from the great cardiac vein: a case report and review of the literature.
A patient underwent radiofrequency (RF) catheter ablation for a drug-refractory ventricular tachycardia, but RF energy application at an endocardial site of the left ventricular outflow tract and at the left sinus of Valsalva could not eliminate the tachycardia. The earliest ventricular activation during the arrhythmia, which preceded the onset of the QRS complex by 32 ms, was found within the great cardiac vein and complete elimination of the tachycardia was finally achieved with RF application at that site.
