• Aortic Coarctation—Adult

    (Coarctation of the Aorta—Adult)

    Definition

    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. It is often associated with other heart and vascular conditions, like abnormal (bicuspid) heart valves or blood vessel outpouching (aneurysms). These conditions carry a risk of additional future problems.

    Causes

    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 in the womb.

    Risk Factors

    A risk factor is something that increases your chance of getting a disease or condition. The following risk factors increase your chances of having aortic coarctation:

    Symptoms

    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.
    • Cold legs and feet
    • Shortness of breath, especially with exercise
    • Dizziness
    • Leg cramps after exercise
    • Headaches
    • Fatigue
    • Nosebleeds
    • Fainting
    • Chest pain

    Diagnosis

    Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include the following:

    Treatment

    Talk with your doctor about the best treatment plan for you. Treatment options include the following:

    Surgery

    The narrow section of the aorta can be removed surgically. The two “good” ends can be reconnected.

    Balloon Angioplasty

    A tiny catheter tube is inserted into a blood vessel in the leg and threaded up to the aorta. There, a balloon is inflated to expand the narrow area. A stent may be placed to keep the area open.
