*What is the most common symptomatic aortic arch abnormality?
Double Aortic ArchDouble aortic arch (persistence of both right and left 4th embryonic arches) is the most common anomaly to cause symptoms. The anomaly results in encircling of the trachea and esophagus, causing tracheal compression and respiratory symptoms. Look for complete or partial DiGeorge syndrome in infants with aortic arch abnormalities.
The most common symptomatic aortic arch abnormality is aortic coarctation. It is a congenital condition in which there is a narrowing of the aorta, which is the major blood vessel that carries blood from the heart to the body. Aortic coarctation can cause high blood pressure, especially in the arms and head, and can lead to complications such as heart failure and aortic aneurysm. It can be diagnosed by physical examination, imaging tests such as echocardiography and MRI, and treated with surgery or balloon angioplasty.
