Quick Summary

Aortic arch atresia is a congenital disorder characterized by the absence of a normal bodily passage or cavity in the aortic arch. This means a part of the aortic arch, which carries oxygen-rich blood from the heart to the rest of the body, is not properly formed at birth. This condition, along with other aortic arch and heart-valve atresias, can cause significant circulatory problems in infants and may require surgical correction. While aortic arch syndrome can also be caused by atherosclerosis in older individuals, aortic arch atresia specifically refers to a birth defect.12
