In vitro hemodynamics favor the Björk-Shiley valve; leaves open translation to clinical outcomes or durability.
Does the Björk-Shiley tilting disc valve improve flow characteristics and reduce pressure gradients compared to other prostheses in an in vitro model?
The Björk-Shiley tilting disc valve demonstrates excellent in vitro hemodynamic performance with the lowest pressure gradient among tested prostheses.
Björk et al. (1970) studied this question.
