Prenatal two‐and three‐dimensional echocardiographic diagnosis of anomalous origin of one pulmonary artery from the ascending aorta: Case report and literature review

Abstract

In utero diagnosis of anomalous origin of one pulmonary artery from the ascending aorta (AOPA) has been rarely reported, although this malformation has a high mortality rate due to the rapid development of pulmonary hypertension. We report two cases of AOPA, in which either the left or the right pulmonary artery originated from the distal part of the ascending aorta. Scanning around the three‐vessel view to search for the origin of the left and right pulmonary arteries is essential for the diagnosis. In addition, recognition of an abnormal vessel at the three‐vessel tracheal view is also useful. Three‐dimensional echocardiography with high‐definition flow imaging and spatiotemporal image correlation technique facilitates the identification of the anomalous origin of the pulmonary artery and should be considered a complementary modality in fetal cardiac examinations.

Prenatal echocardiographic diagnosis of left pulmonary artery discontinuons with Taussing-Bing syndrome:case report and literature review

“…Summarizing the previous experience, there is a consensus among sonographers performing fetal malformation screening that conducting a continuous scan enables the acquisition of more comprehensive anatomical information 10 . In challenging cases where identi cation of the ipsilateral pulmonary artery origin proves di cult, it is recommended to perform upstream scanning from the hilum to locate its origin and course.…”
