Abstract:
Objective: To assess the hydrodynamic performance of C L pugestrut valve prosthesis in vitro . Methods: The leakage, steady flow and pulsatile flow of the valve prosthesis was tested in vitro with the C L standard valve and Medtronic Hall valve prosthesis as control. Results: The rate of leakage of the C L pugestrut valve was (298?66) ml/min, accorded with the demand of clinical use. The steady flow pressure drop across the C L pugestrut valve was significantly lower than the C L standard valve( P
