[Comparative hydrodynamic study of artificial heart valves in pulsating flow].
A comparative hydrodynamic study of artificial heart valves with spherical, hemispherical and lentil-shaped obturative elements has been carried out under the non-stationary conditions. The valves resistance coefficient is higher in the lentil-shaped valves. With the increase of pulse rate the stroke volume of the valves of all the types drops, and the regurgitation increases.

[Temporal characteristics of the movement of the cut-off elements of artificial heart valves in a pulsing flow].
A comparative investigation of time characteristics of the movement of artificial heart valves with spherical, hemispherical and lentil-shaped obturative elements under non-stationary conditions was carried out. It has been found that it is practically impossible to avoid the delay in the valve closing and opening, as well as the regurgitation phenomena, on the valve prothesis, due to the inertia of obturative elements and attached masses. A searching for new models of the heart valves should go on.
