coarctation of the aorta
Last edited 01/2023 and last reviewed 02/2023
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.
