In principle, the blood volume passing through a stenotic valve (aortic stenosis ... 57 0.18 indicative of severe aortic stenosis.Pk Grad=peak gradient; Mn Grad=mean gradient ...

There’s room on the market for new TAVI valves as long as they can compete with the best in practice, a researcher says.

The most important hemodynamic parameters for staging are the maximum transaortic velocity (V max), the mean pressure gradient (ΔP) across the aortic valve, and the aortic valve area (AVA).

The type of aortic stenosis was clarified by subtype (based on mean aortic valve gradient and LVEF) and guideline-based recommendations for management and further evaluation were provided. In the ...
