Mild AS. Note the limited motion and decreased valve opening of the AV.

Mild AS.  Note the calcification, limited motion and decreased valve opening of the AV. Color displays post-stenotic turbulence in the aortic root and aortic insufficiency.

Mild AS caused by a fixed right aortic cusp with atherosclerosis. M-mode would be helpful in demonstrating the lack of movement of the right cusp.

Mild AS demonstrated with limited valve leaflet motion and atherosclerosis.

Note the significant calcification of the aortic leaflets but the valve motion is still relatively preserved.

This is the PLAX view of the same patient from the video above. Note the mild amount of post-stenotic turbulence which correlates with mild stenosis.

The AV demonstrates significant calcification and limited movement of the right and non cusps. Mild left ventricular hypertrophy is also present and related to AS.

Severe aortic stenosis.  Note the post stenotic turbulence and artifact from the stenosis.  LVH is also demonstrated.

Severe aortic stenosis with MAC.  Note the thickened AV leaflets with poor mobility.

Severe aortic stenosis with MAC.  Note the post stenotic turbulence and diminished amount of flow passing through valve.

Severe aortic stenosis with MAC.  Note the calcification and post stenotic turbulence. The apical 5 chamber view is preferred for Doppler evaluation of the valvular flow.

Severe aortic stenosis with significant AV calcification.

Severe aortic stenosis with significant AV calcification.

Severe aortic stenosis with significant AV calcification.

TEE with severe aortic stenosis.  Note the significant amount of post stenotic turbulence indicated by the green color when using a variance color map.  There is also moderate to severe AI.

3D evaluation of the aortic valve is helpful to assess suspected stenosis. This case demonstrates significant stenosis of the aortic valve.
