The in vitro cavitation thresholds and locations were studied on ten different heart valve designs. The valves were mounted in a mock circulation flow loop which simulated a cardiovascular system. All the tests were run at 70 beats per minute with a cardiac output varying between 2 l/min and 6 l/min in increments of 1 l/min. In vitro cavitation phenomena generated at the closing instant of mechanical heart valves were captured using a video photographic technique. Cavitation locations and… CONTINUE READING
