Coarctation of the aorta

Coarctation of the aorta is narrowing of the aorta at, or distal to, the origin of the left subclavian artery at the insertion of the ductus arteriosus.

  • most common location for coarctation of the aorta is just distal to the left subclavian artery at the point where ductus arteriosus connects to the aorta (1)

As a result of the severe narrowing of the aorta a collateral circulation is encouraged which involves the periscapular and intercostal arteries. There may be a decreased renal perfusion which can lead to the development of systemic hypertension which may persist despite surgical intervention.
