Time Resolved PIV and LDA measurment were conducted for the study of the fIow field generated by the mechanical bi-leafIet mitral valves, the SJM and the Jyros valves, to find out the effect of the valve designs and the installed orientations on the fIow. Results from the time resolved PIV system were very comparable to the LDA results. In both orientations, the JR valve generated much higher turbulent stresses.
