Parents: It's a genetic defect. It is not acquired. It's due to faulty genes.
Dr. Rick Koch

Congenital : Can also be associated with bicuspid aortic valve.
Dr. Sarosh Batlivala
Pediatric Cardiology 16 years experience
Narrowing: Coarctation usually occurs near the site of the pda. The PDA is a normal channel in the fetal circulation which helps blood bypass the lungs (since fetuses don't breathe). When the baby is born, the PDA constricts and closes. In some patients, the aorta also become constricted and leads to coarctation.

Congenital: It is a cogenital defect and is present in utero ( before birth).

Born with it: Coarctation is a form of congenital heart disease. One is born with the defect. It can be surgically corrected.

A 21-year-old member asked:

Is aortic dissection always a result of this syndrome, or are there other causes?

Emergency Medicine 25 years experience
No: Certain syndromes such as eds, marfan, and turner predispose to aortic dissection but many other causes exist. A bicuspid aortic valve and recent valve surgery increase the risk of aortic dissection. Aortic dissection also tends to run in families (even if those family members don't have Marfan or ehlers-danlos, or one of the other associated syndromes.

How do doctors diagnose coarctation of the aorta?

Dr. Alon Gitig
Cardiology 20 years experience
Physical exam/scans: Coarctation, because it causes obstruction to blood flow through the aorta, will impede normal flow into the lower half of the body. Therefore, it can be detected by measuring accurate blood pressures in the legs and arms, and noting a severe drop-off in the legs. Ct or MRI scans are used to confirm the diagnosis and pinpoint the precise location of the coarctation.

Does any one know what causes the coarctation of the aorta in people?

Dr. Robert Vorhies
Vascular Surgery 25 years experience
Abnormal embryology: By definition coarctation of the aorta is a abnormality of vascular embryology. At birth flow is adequate for the limited activity i the new born and early toddler years, but as children age, their growing bodies and activity out grows the narrowed aorta's ability to supply enough blood fast enough to keep up.

Dr. Payam Mehranpour
Cardiology 23 years experience
Narrowing of aorta: Coarctation of the aorta is a congenital disease, i.e. Present at birth. It is a narrowing of the aorta, usually near the ductus arteriosus insertion to the aorta. Mild forms may not cause much symptoms early in life. Treatment depends on severity and location, which may be conservative in mild forms. Surgery (or catheter based procedures) may be needed in more severe forms.
