[Experimental study of artificial disk heart valves].
The paper provides the results of an experimental study of domestic artificial EMIKS disk cardiac valves during simulated pulsing flow. The operation valves was examined in the aortic position by photochromic visualization. The patterns of flow velocities beyond the valves during the whole operating cycle were obtained. The models of EMIKS valves at opening angles of 65 degrees and 80 degrees and the model with acoustic clearance in the design of a disk movement stopper were exploded. The findings may be useful for cardiac valves designers in evaluating the impact of designing features of a valve on its hydrodynamic characteristics.
