The 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.

Aortic 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 womb.
Risk factors include:
If your child’s condition is severe, he 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, he may have these symptoms during childhood, such as:
These symptoms may be caused by other conditions. If your child has any of these, talk to the doctor.
If your child’s condition is not detected at birth, the doctor will ask about his symptoms and medical history. A physical exam will also be done. Tests may include:
Talk with the doctor about the best treatment plan for your child. Treatment depends on your child's age and how severe the condition is.
Your newborn will need treatment right away. An IV medicine (given through a vein) called prostaglandin may be given. This drug helps keep blood flowing to all parts of the body. Other medicines may also be used to improve how the heart contracts. One of the most common surgeries involves removing the narrow section of the aorta and reconnecting the two "good" ends.
Your child may need to take water pills to reduce fluid retention. Depending on your child’s condition, the doctor may also recommend surgery. Some of the options include:
It is important to note that there will always be a risk, even into adulthood, of the development of other cardiovascular conditions.
