In vitro hydrodynamic differences between bileaflet valves require clinical correlation; leaves open optimal prosthesis selection.
Does the Edwards-Duromedics bileaflet aortic valve prosthesis differ from the St. Jude prosthesis in hydrodynamic characteristics in an in vitro model?
In an in vitro model, the Edwards-Duromedics bileaflet valve demonstrated less regurgitation but a higher transvalvular pressure gradient and smaller orifice area compared to the St. Jude valve.
Chandran et al. (1988) studied this question.
