Abstract

"Mechanical heart valve (MHV) flows are characterized by high shear-stress, regions of recirculation and high levels of turbulent fluctuations which are hostile for blood. In the ongoing effort to reduce long-term complications and to reduce fatalities, it is important that the flow characteristics of the mechanical valves in all possible flow conditions are understood. Little research has been done to study the flow through bileafet MHVs at low heart beat rate. As an initial effort, the present study is aimed at developing a new measurement method to study the fluid characteristics at the exit of custom-made bileafet mechanical heart valves induced by a piston driven periodic flow at 45 beats per min. Ultrasonic Doppler Velocimetry (UDV) method providing spatiotemporal information was employed to map the flow field."--Abstract, page iii.
