Diagnostic Considerations

The differential diagnosis of coarctation of aorta depends on the patient's clinical presentation.

Neonates with heart failure may present with the following:

  • Coarctation of aorta
  • Severe obstruction to left heart (eg, hypoplastic left heart syndrome, severe critical aortic valve stenosis)
  • Sepsis
  • Myocarditis
  • Perinatal hypoxia

Patients with unequal pulses and blood pressures may present with the following:

  • Peripheral arterial disease (due to atherosclerosis, or arterial thrombosis from previous catheterization)
  • Prior surgical ligation (history of Blalcock-Taussig shunt)
  • Aortic dissection
  • Supravalvular aortic stenosis
