We have studied the flow through various cardiac valves prostheses, with the assistance of an artificial left ventricular pump. We took photographs during the whole of the cardiac cycle but we present here only the view of the middle systolic period. As regards the mechanics prostheses (Bjork-Shiley, Lillehei-Kaster, Saint-Jude-Medical, Starr-Edwards) the flow changes with the shape and opening of the valve. Biologic prostheses (Carpentier-Edwards, Hancock, Ionescu-Shiley) present an impertubated flow.
我们借助人工左心室泵研究了通过各种心脏瓣膜假体的血流情况。我们在整个心动周期中都拍摄了照片,但在此仅展示收缩中期的视图。对于机械瓣膜假体(Bjork-Shiley、Lillehei-Kaster、Saint-Jude-Medical、Starr-Edwards),血流会随着瓣膜的形状和开口而变化。生物瓣膜假体(Carpentier-Edwards、Hancock、Ionescu-Shiley)呈现出无扰动的血流。
