Abstract

Since the first implantation of an artificial heart valve by Hufnagel in 1952, many research workers proposed different types of such artificial valves. Up to this time none of the proposed models satisfied all the criteria necessary for an ideal valvel:
  • biocompatibility

  • no material fatigue

  • limited pressure gradient across the valve, in order to restrict valve power loss

  • backflow less than 5% of forward flow

  • limited turbulent flow in order to prevent hemolysis

  • sufficient washout to avoid thrombogenesis

  • no sharp boundaries and smooth closure.
