Abstract
As discussed in earlier work (1), proper understanding of natural aortic valve closure is essential for the design of artificial triple leaflet valve prostheses. Some insight in valvular closing during deceleration of the main stream has been obtained from model studies (2, 3, 4). The present study was conducted in order to investigate this closing behaviour in animal experiments and to compare the results with those obtained from the theoretical model designed on the basis of the fluid behaviour in the analogue (5). Aortic valve movements were studied in open-chest dogs using direct high-speed cinematography. The aortic valve is schematically shown in Figure 1; it has three leaflets and behind each leaflet there is a half-spherical cavity, the sinus of Valsalva.
