Coarctation of the Aorta

Patients may be asymptomatic in a setting of a non-severe stenosis. Children and adults can present with angina pectoris and leg claudication.

As with many congenital abnormalities, coarctation of the aorta is associated with other congenital anomalies. Useful in assessing for infantile coarctations. The suprasternal notch-long axis views are particularly considered helpful.

The fetal right ventricle can be appear enlarged in severe coarctations although arotica alone is not a specific feature.

Occasionally an aortic arch view may directly show a narrowing. All modalities are capable of delineating the coarctation as well as collateral vessels, most common collateral pathway being subclavian artery to internal mammary artery to intercostal arteries resulting in inferior rib notching to post-coarctation part of descending thoracic aorta.


The urgency of treatment depends on the presence of congestive cardiac failure. This is usually the case in severe coarctations found in infancy.

Treatment can be either primary surgical repair with excision of the coarctation and end-to-end anastomosis, or balloon angioplasty. Subclavian flap repair is a common surgical technique used, where the origin and proximal left subclavian artery is excised, coartaciob up and sutured onto the aorta. If the subclavian is ligated, it is usually anastomosed onto the left common carotid artery.
