Web10 de mai. de 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 ]. WebA review article explores the variety of methods available for assessing prosthetic aortic valve function and considers causative factors which may contribute to high transvalvular gradients in an attempt to determine whether a physical problem with the valve exists, or whether the valve is functioning normally.
