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 heart valves or blood vessel outpouching. These conditions carry a risk of additional future problems.
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.
Men are at increased risk. Other factors that increase your chances of having aortic coarctation include:

Since aortic coarctation is a congenital defect, it cannot be prevented.
