Coarctation of the aorta describes a congenital narrowing of the descending aorta. It is more common in males, despite an association with Turner's syndrome.

Associations

• Turner's syndrome
• bicuspid aortic valve
• berry aneurysms
• neurofibromatosis

Features

• infancy: heart failure
• adult: hypertension
• radio-femoral delay
• mid systolic murmur, maximal over the back
• apical click from the aortic valve
• notching of the inferior border of the ribs (due to collateral vessels) is not seen in young children
