Compared with the existing literature on complete late repair of tetralogy of Fallot in children, this study showed good early results with no mortality, similar rates of reintervention and valve-preserving surgery, higher ICU and hospital length of stay, higher incidence of significant residual right ventricular outflow tract stenosis, and lower incidence of significant pulmonary insufficiency. Repair with a transannular patch was a risk factor for significant residual right ventricular outflow tract stenosis and significant pulmonary insufficiency.
