(Coarctation of the Aorta—Child)
DefinitionThe aorta is the main artery in the heart. It carries oxygen-rich blood from the heart to the body. Aortic coarctation is the narrowing of the aorta. This slows or blocks blood flow. It is often associated with other heart and vascular conditions. Examples include abnormal heart valves or aneurysms, which can lead to further health problems.

CausesAortic coarctation is a congenital heart defect. This means that it is present at birth. It occurs because of a problem with the way the aorta develops while the fetus is growing in the uterus.
Risk FactorsAortic coarctation is more common in boys. Other factors that increase your child's risk of aortic coarctation include:
- Genetic disorders, such as Turner syndrome
- Other heart defects
SymptomsIf your child’s condition is severe, they will have symptoms of impaired blood flow at birth. If aortic coarctation is not treated, it can lead to heart failure. If this condition is not detected when your child is a baby, there may be other symptoms during childhood, such as:
- Heart murmur
- High blood pressure in the arms
- A weak pulse in the legs
- Cold legs and feet
- Shortness of breath, especially with exercise
- Legs that are underdeveloped, but better developed arms
- Chest pain
