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.
