Abstract: The aorto-pulmonary window (AWP) is a rare congenital heart disease which represents 0.1% of all congenital cardiac diseases. It is an abnormal communication between the ascending aorta and the pulmonary trunk in the presence of two separate semilunar valves (1). The diagnosis is generally made in the postnatal period due to severe pulmonary arterial hypertension (Eisenmenger syndrome).Incidental discover in the adult life is extremely rare. To our knowledge, asymptomatic adult case has not been reported until now in our country. We report through this manuscript an incidental discover of an aorto pulmonary window, in a 40 years old man. Different imaging modalities have been described. Thus, APW should be considered in the differential diagnosis of the severe pulmonary hypertension also in adult patients.
