Abstract

Abstract

In order to evaluate the opening and closing states and fatigue properties of a new type of polyoxymethylene heart valve, accelerated fatigue tests were performed on the polyoxymethylene heart valve and an ON-X heart valve using the heart valve prostheses fatigue tester (TH-2200). The opening and the closing positions of the leaflets were tracked using the high speed camera, and the instantaneous motion states of valves were investigated. The results show that the new heart valve had a similar opening-closing cycle at the same frequency with the ON-X heart valve in in vitro accelerated fatigue experiments, and the leaflets of both the valves would generate jitters when they opened to the limit position. After 3×108 cycles of fatigue tests, no obvious wear was found on the valve ring, the valve leaflets rotated flexibly, and the heart valve was working properly.
