...Mechanical valves usually made from metal and fabrics are very durable but they have poor hemodynamic and are thrombogenic requiring permanent anticoagulation. Tissue heart valves constructed from biological tissues have excellent hemodynamic blood flow, but they lack durability. The project proposed a new valve design that is similar to a stentless tissue valve but made from a synthetic material, Polytetrafluoroethylene (PTFE)... The scope of this project includes designing a fixture to accommodate the valves in the ViVitro System and studying hemodynamic parameters such as pressure drop, flow rate, and dynamic leaflet behaviour of the valves. ...Go to the Article
