Differential diagnosis

Investigations

  • Echocardiogram
  • ECG: may show left ventricular hypertrophy
  • Chest x-ray
  • Blood cultures, if considering infective endocarditis

Management

Asymptomatic patients should be managed conservatively with regular echocardiogram follow-up.

The following patients should be treated surgically:

  • Symptomatic patients
  • Echocardiographic evidence of severe aortic stenosis:
    • <1cm2 aortic valve area
    • Pressure gradient >40 mmHg across the aortic valve

Complications
