Coarctation of the aorta

Definition

Aortic coarctation is a narrowing of part of the aorta (the major artery leading out of the heart). It is a type of birth defect. Coarctation means narrowing.

Alternative Names

Aortic coarctation

Causes, incidence, and risk factors

The aorta carries blood from the heart to the vessels that supply the body with blood and nutrients. If part of the aorta is narrowed, it is hard for blood to pass through the artery.

Aortic coarctation is more common in persons with certain genetic disorders, such as Turner syndrome. However, it can also be due to birth defects of the aortic valves.

Aortic coarctation is rare. It is usually diagnosed in children or adults under age 40.
