Abstract
Two typical contemporary mechanical heart valves, with different designs (St. Jude Medical and Medtronic-Hall), were tested in the mitral position under pulsatile flow conditions. The test program used the flow visualization technique to map the velocity field inside the simulated ventricle. The study was carried out using a sophisticated cardiac simulator in conjunction with a highspeed video system (200 frames/s). The continuous monitoring of velocity vector time histories revealed useful details about the complex flow and helped establish the location and time of the peak parameter values. We conclude that (1) the SJM valve with antianatomical position creates a large single circulatory flow; and (2)the configuration of the MH valve seems to affect the flow characteristics more dramatically, and the posterior orientation exhibits a simple and stable circulatory flow.
