Web10 mei 2024 · In adults with normal aortic valves, the valve area is approximately 3.0 to 4.0 cm 2. As aortic stenosis (AS) develops, minimal pressure gradient is present until the orifice area becomes less than half of normal. The pressure gradient across a stenotic valve is directly related to the valve orifice area and the transvalvular flow [ 1 ]. WebThe degree of severity is assessed using several components of the ultrasound exam, especially Doppler ultrasound, which measures the direction and flow of blood as it courses through the heart.
