Approximate Synonyms
  • Abdominal aortic coarctation
  • Coarctation abdominal aorta
  • Postductal coarctation of aorta
  • Preductal coarctation of aorta
Clinical Information
  • A birth defect characterized by the narrowing of the aorta that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial hypertension before the point of narrowing and arterial hypotension beyond the narrowed portion.
  • Congenital constriction of the aorta just distal to the left subclavian artery; causes upper body hypertension but few other symptoms; may present as headache or dyspnea on exertion.
  • Congenital narrowing of a segment of the aorta. Signs and symptoms include hypertension, muscle weakness, shortness of breath, headaches and leg cramps.
