The kidneys are especially sensitive to changes in blood pressure and blood flow and may not function as effectively or become damaged over time from the abnormal pressure and decreased blood flow caused by the obstruction. One important function of the kidneys is to help control blood pressure by regulating salt and water retention which can add to the problems associated with high blood pressure caused by the coarctation. The segments of the aorta behind the obstruction may become enlarged because of the increased pressure caused by the obstruction. If aneurysm, rupture or dissection occurs in these arteries a stroke results. This risk is increased further if a bicuspid aortic is valve present.
Endocarditis precautions are necessary for life.
The coronary arteries may develop premature narrowing or atherosclerosis as a response to the increased blood pressure. This may result in coronary artery disease such as a heart attack or angina in early to mid adulthood. Return to the top Treatment Coarctation of the aorta is generally treated surgically by removing the area of obstruction. Medication is often required to manage associated hypertension especially in the adult. A surgical repair that was done in childhood may be out grown and need to be redone in adulthood.
