No immediate change to prosthetic valve selection; leaves open hemocompatibility questions for in-vivo validation.
In-vitro measurements demonstrate that trileaflet valves generate higher peak turbulent shear stresses than tilting disk valves, though stresses decrease more rapidly downstream for the tilting disk valve.
Tiederman et al. (1986) studied this question.
