Abstract:
A case of prenatally diagnosed aortopulmonary window is reported. The mother was referred for fetal echocardiography at 26 weeks' gestation because of suspected congenital heart disease. Prenatal echocardiography showed an aortopulmonary septum defect close to the pulmonary artery bifurcation and a left-to-right shunt flow in systole and early diastole detected by color flow Doppler. Postnatal echocardiography confirmed prenatal diagnosis, the aortopulmonary window was a 9-mm type III aortopulmonary window. An atrial septal defect with shunt flow left to right was also found. Surgical repair was performed 4 weeks after birth, the postsurgical period was uneventful and the newborn was discharged without complications 7 days after surgery.
