The Abiomed valve's poorer opening characteristics warrant caution in synthetic valve development; leaves open whether design refinements can achieve parity with tissue or mechanical valves.
Does the Abiomed polyurethane trileaflet valve have comparable hydrodynamic performance to tissue and mechanical valves in an in vitro model?
The Abiomed polyurethane trileaflet valve demonstrated significantly poorer opening characteristics compared to standard tissue and mechanical valves in hydrodynamic testing, highlighting design challenges for synthetic trileaflet valves.
Leat et al. (1993) studied this question.
