Abstract

The diagnosis of a discontinuous left pulmonary artery arising from a left ductus arteriosus was made by two-dimensional and Doppler echocardiography in an infant with recurrent pneumonia. The diagnosis was later confirmed at cardiac catheterization and surgery. The suprasternal notch views were especially useful for the identification of the left pulmonary artery. In this patient with a right aortic arch, the left pulmonary artery was supplied by a left ductus arteriosus that arose from the innominate artery. This case report describes the echocardiographic diagnosis of discontinuous left pulmonary artery as an isolated lesion, an unusual lesion that can easily be missed. It emphasizes the necessity of a careful and complete examination with particular emphasis on pulmonary artery continuity in patients suspected of having congenital heart disease or respiratory compromise as a result of a cardiovascular cause.
