Detection of aortopulmonary window with ventricular septal defect by Doppler color flow imaging

Aortopulmonary window is a rare congenital cardiac anomaly. When it coexists with a ventricular septal defect, the accurate diagnosis of aortopulmonary window on the basis of clinical examination is difficult. We report the case of an infant who had an aortopulmonary window together with a ventricular septal defect. An accurate diagnosis could be attained by visualization of the defect using two-dimensional echocardiography and detection of the flow through it by Doppler color flow imaging.
