Krisha McCoy, MS DefinitionThe 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.
CausesAortic 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 uterus. Risk FactorsMen are at increased risk. Other factors that increase the chances of aortic coarctation:
SymptomsAortic coarctation may or may not have symptoms. When present, symptoms may include:

Treatment options include the following: SurgeryThe narrow section of the aorta can be removed surgically. The 2 healthy ends can be reconnected. Balloon AngioplastyA 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.
