Does radiofrequency catheter ablation using pace mapping successfully treat RVOT VT late after repair of tetralogy of Fallot?
Radiofrequency catheter ablation using pace mapping can successfully treat RVOT VT in patients late after surgical repair of tetralogy of Fallot.

May inform ablation decisions in rare post-repair RVOT VT; hypothesis-generating and requires prospective validation.
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.
