Origem anômala da artéria pulmonar direita em aorta ascendente (hemitruncus)

Abstract

The origin of the right pulmonary artery from the ascending aorta is a rare cogenital anomaly, with very few reports in the literature. We describe two cases of this rare malformation, one of them, associated with interruption of the aortic arch (type B). In both cases, the diagnosis was made by two-dimensional echocardiography, with angiographic confirmation in one of them. The origin of the right pulmonary artery was close to the aortic valve, anomaly pathogenetically distinct from the type that arises close to the innominate artery.

Abnormal Origin of the Pulmonary Artery from the Ascending Aorta in the Neonate

“…Question B: The transthoracic doppler echocardiogram is useful for diagnosis [ 5 , 6 , 7 , 8 , 9 , 10 ] , and some patients might be operated on based solely on its information [ 5 , 11 ] . The subcostal short axis view at the level of the great arteries [ 5 ] , as well as the suprasternal and short axis longitudinal view, can usually establish the diagnosis.…”
