High shear stresses in MHV flow separation may signal hemolysis or thrombosis risk; leaves open clinical translation pending in vivo studies.
In vitro testing of 10 mechanical heart valves demonstrated significant velocity and shear stress peaks during systole, highlighting areas of flow separation and momentum exchange.
Giersiepen et al. (1989) studied this question.
