title: [Relief of the internal surface of the left-ventricular wall at different phases of cardiac activity and its functional role].
abstract: The work has investigated 33 preparations of the heart taken at random from people who died not of a heart pathology. The heart chambers were filled with protacryl . It was shown that when changing from systole to diastole a rotating clockwise movement of ventricle walls took place round its long axis. The fact is of great importance for the formation of the intracardiac hemodynamics. It should be taken into consideration when prosthesing the valves and developing new designs of the artificial heart valves responsible for twisted blood flow.
