title: Radiofrequency catheter ablation of right ventricular outflow tract tachycardia late after complete repair of tetralogy of Fallot using the pace mapping technique.
abstract: While surgical repair of tetralogy of Fallot has improved the long-term outlook for this patient population, sudden death late after repair remains a problem. Ventricular tachycardia (VT) originating in the right ventricular outflow tract (RVOT) is a well described, clinically important finding following surgical repair of tetralogy and a number of investigators suggest that this VT plays a critical role in the etiology of sudden death. We report two patients with RVOT VT late after repair of tetralogy who underwent successful radiofrequency ablation of their tachycardia.
