Overview

Two dimensional echocardiography plays an important role in the diagnosis of bicuspid aortic stenosis. Bicuspid aortic stenosis is important to diagnose because of the associated risk of endocarditis and the risk of progressive valvular stenosis.

Echocardiographic Findings in Bicuspid Aortic Valve Disease

  • The short axis view is useful, but doming of valve can best be seen on the parasternal long axis.
  • Echocardiographic features that are associated with a poor prognosis in asymptomatic patients and progression to a symptomatic state include moderate to severe calcification and a peak aortic velocity > 4.0 M/s. [1]
