- Flow acceleration noted in the ascending aorta (from valvar aortic stenosis)
- Aortic stenosis
- Continuous wave Doppler in the ascending aorta
- Spectral Doppler velocities and mean gradient consistent with moderate to severe aortic stenosis

The suprasternal notch is an excellent view to profile the ascending aorta. It is an optimal view to assess the degree of aortic stenosis by spectral Doppler as the velocity of interrogation is relatively parallel. This view is also useful for measuring the dimension of the ascending aorta.
- Probe placed in suprasternal notch
- Notch pointed towards 1 o'clock
- Tilt inferiorly and anteriorly
- Valvar aortic stenosis (quantification of stenosis by spectral Doppler)
- Supravalvar aortic stenosis
- Dilation of the ascending aorta
