These in vitro differences should not guide valve selection; leaves open clinical impact on thrombosis or outcomes.
Does the type of prosthetic heart valve affect pressure drop and flow turbulence in an in vitro aortic model?
In an in vitro model, the Björk-Shiley prosthetic valve demonstrated a smaller pressure drop compared to Kay-Suzuki and SAM-MT valves, highlighting differences in fluid mechanics and turbulence that may relate to thrombus formation.
Fukushima et al. (1982) studied this question.
