[Experimental study of the hydrodynamics of modern artificial heart valves]

The paper presents the results of experimental studies of the hydrodynamics of currently available artificial cardiac valves (ACV). Photo chromatographic visualization was used to study the hydrodynamics of ACV. The hydrodynamic characteristics of a MIX discal valve (Russia) and a St. Jude two-leaflet one (USA), which have been clinically applied for more than 15 years, are presented.
