- Aortic stenosis
- Functionally unicommissural aortic valve
- Thickened and dysplastic aortic valve leaflets
- Aortic stenosis
- Functionally unicommissural aortic valve
- Thickened dysplastic aortic valve leaflets
- Turbulent flow noted across valve by color Doppler
- Trivial aortic regurgitation
- Critical Aortic Stenosis
- Severely dysplastic thickened aortic valve leaflets with fused commissures with tiny effective pinhole oriface
- Critical Aortic Stenosis
- Endocardial fibroelastosis with echobright endocardium and hyperechogenic mitral valve papillary muscles
- Severely depressed left ventricular systolic function
The parasternal short axis view is best for determining the morphology of the aortic valve leaflets, which is important in regards to defining the etiology of aortic valve stenosis in children, which is most commonly due to commissural underdevelopment.
- Left sternal border
- 3rd of 4th intercostal space
- Notch pointing towards the left shoulder (1-2 o'clock)
- Bicommissural or unicommissural aortic valve (profiles which leaflets underdeveloped/fused)
- Aortic regurgitation (site of origin)
- Assess fusion of specific aortic valve cusps/commissures
