Aortic Stenosis

Aortic Stenosis

Obtain apical four chamber view (see LV slide) with straight septum
Fan/sweep + obtain 5 chamber view.
Rock/heel to maintain aortic valve as vertical as possible.
Click continuous wave doppler and place CW marker within the aortic valve.
Click aortic valve measurement + trace parabolic shape.
Assessment of Vmax:
- Mild: < 3m/s
- Mod: 3-4 m/s
- Severe: > 4m/s
- Critical: > 5m/s (or over 4 with symptoms)
- Note: In low flow states these values may not be accurate.

Note: General inspection of the valve is also important (ie for calcifications), the video shown here is a normal aortic valve!
