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 surgicaJ 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.
