(Coarctation of the aorta)
The aorta is the main artery carrying oxygen-rich blood from the heart to the body. Aortic coarctation is the narrowing of the aorta which slows or blocks the blood flow.
Heart and Main Vessels
Aortic coarctation is a congenital heart defect, which means it is present at birth. It occurs because of a problem with the development of the aorta while the fetus is developing in the womb.
A risk factor is something that increases your chance of getting a disease or condition. The following factors increase your chances of having aortic coarctation. If you have any of these risk factors, tell your doctor:
- Gender: male
- Turner’s syndrome
- Aortic valve abnormalities
Aortic coarctation may or may not have symptoms. If you experience any of these symptoms, do not assume it is because of aortic coarctation. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.
Your doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include the following:
Talk with your doctor about the best treatment plan for you. Treatment options include the following:
The narrow section of the aorta can be removed surgically, and the two “good” ends reconnected.
A tiny catheter tube is inserted into a blood vessel in the leg and threaded up to the aorta, where a balloon is inflated to expand the narrow area. A stent may be placed to keep the area open.
