Aortopulmonary window coexisting with tetralogy of Fallot

Aortopulmonary window is a rare cardiac malformation presenting either in the isolated form, or in association with other cardiac anomalies. The isolated form usually presents an increased pulmonary blood flow as the main clinical feature, but if associated with other cardiac anomalies the clinical findings change according to the additional defect. Only 19 cases of aortopulmonary window associated with tetralogy of Fallot have been reported. Five of them have associated pulmonary atresia. We report two neonatal cases of aortopulmonary window and tetralogy of Fallot, one of them presenting an associated pulmonary atresia.
