Does the CarboMedics Kinetic bileaflet prosthetic heart valve improve hydrodynamic characteristics compared to the St. Jude Medical heart valve in an in vitro model?
In an in vitro pulse duplicator model, the CarboMedics Kinetic bileaflet prosthetic heart valve showed superior hydrodynamic performance compared to equivalent St. Jude Medical valves.
Janet S. Baldwin (1997) studied this question. CarboMedics kinetic cardiac valve prosthesis vs. St. Jude Medical (SJM) heart valve was evaluated on Hydrodynamic characteristics (forward flow pressure drop, regurgitant volume, and energy loss). The CarboMedics Kinetic valve demonstrated superior fluid dynamics compared to equivalent St. Jude Medical valves, with 8-14% lower pressure drops and 5-10% greater effective orifice areas.
