A Comparison of Five Mechanical Heart Valves Investigated in a Pulse Duplicator System with Flexible Vessels - Ein Vergleich von fünf mechanischen Herzklappen untersucht in einem Kreislaufsimulationsmodell mit flexiblen Gefäßen
Abstract:In order to determine the effectiveness of mechanical heart valves, two different types of mechanical heart valves, three tilting disc valves (BS-SD, BS-CCD, BS-M) and two büeaflet valves (St. Jude Medical, Duromedics) all with the same size of annulus diameter -d A = 29 mmwere investigated in the mitral position of a mock circulation under pulsatile flow conditions. Flow, pressure, and orifice area were measured. Insufficiency, mean orifice area, discharge coefficient, performance index and efficiency index w… Show more
