No support for preferring curved-leaflet valves on fluid-dynamic grounds; leaves open whether leaflet geometry affects clinical outcomes.
Does the Edwards-Duromedics bileaflet valve offer fluid dynamic advantages over the St. Jude valve in an in vitro model?
In vitro laser anemometry showed no fluid dynamic advantage for the curved leaflet geometry of the Edwards-Duromedics bileaflet valve compared to the St. Jude valve.
Fatemi et al. (1989) studied this question.
