Anomalous Origin of the Right Coronary Artery from the Pulmonary Artery in a Neonate with Turner Syndrome and Aortic Arch Hypoplasia.

Anomalous origin of the right coronary artery from the pulmonary artery, a rare congenital cardiac defect, is typically not diagnosed during infancy. On the other hand, Turner syndrome is usually diagnosed early, and it is classically associated with bicuspid aortic valve and aortic coarctation. Individuals with Turner syndrome are also at increased risk for coronary artery anomalies.
