Pressure recovery in the ascending aorta accounted for up to 44% of the maximal pressure drop and directly correlated to the Gorlin-derived aortic valve area (r=0.80).

Pressure recovery in the ascending aorta can account for up to 44% of the maximal pressure drop in aortic stenosis and is dependent on the ratio of effective valve area to ascending aorta cross-sectional area, which may be clinically relevant in mild to moderate stenosis.
Wolfgang Andreas Schöbel (1999) conducted an observational in aortic valve stenosis (n=37). High-fidelity multi-tip micromanometer catheterization was evaluated on Amount of pressure recovery within the ascending aorta (r=0.80). Pressure recovery in the ascending aorta accounted for up to 44% of the maximal pressure drop and directly correlated to the Gorlin-derived aortic valve area (r=0.80).
