It has been reported that the normally functional bileaflet valve ATS with open-pivot design does not exhibit a full opening motion either in the mitral or in the aortic position in patients. An in vitro experiment was conducted to investigate the mechanism of the ATS leaflet movement. ATS 29 mm for the mitral position was chosen in our experiment and SJM(More)
The non-fully open phenomenon of the advancing standard medical bileaflet heart valves (the ATS valve) are frequently observed in clinical cases, even though there is no problem with their hemodynamic function. The movement of the leaflets was affected easily by the transvalvular flow because of the unique open pivot design of the ATS valve. In this paper,(More)
