Coarctation of the aorta - Overview

Alternative Names

Aortic coarctation

Definition of Coarctation of the aorta:

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.

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 one of the more common heart conditions that are present at birth (congenital heart conditions). It is usually diagnosed in children or adults under age 40.

Coarctation of the aorta may be seen with other congenital heart defects, such as:

Bicuspid aortic valve
Defects in which only one ventricle is present
Ventricular septal defect
