Echocardiography in Bicuspid aorta
- 2D echocardiography plays an important role in the diagnosis of bicuspid aortic stenosis.
- Short axis is useful, doming of valve can be seen on the parasternal long axis.
- Important to diagnose because of risk of endocarditis and calcification with progressive valvular stenosis.
- Only 25% of patients with congenital aortic stenosis{AS) have aortic insufficiency(AI) compared with 75% of cases with acquired AS.
- In 75% of those with acquired AS, there is associated mitral valve disease. This association is rare in congenital AS.
- Congenital AS may occur with one or three cusps, but two cusps is the most common.
- 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]
