Right Ventricular Outflow Tract Reconstruction With an Allograft Conduit in Patients After Tetralogy of Fallot Correction: Long-Term Follow-Up

Right ventricular outflow tract reconstruction after previous TOF repair can be performed with low risk and a low reintervention rate. Allograft conduits function satisfactorily in the pulmonary position at longer-term follow-up. Functional status after allograft implantation in patients with a previous correction of TOF remains good. There is concern about the long-term survival and the occurrence of heart failure.
