Conclusion

The results of study of hydrodynamic characteristics of various ACVs in the steady-state and pulse flow modes showed that the flow behind an ACV has an elaborate structure. The PCI method allows determination of the flow structure and its dependence on the design features of the ACV model under study. Such study allows prediction of the valve functioning after implantation. Hydrodynamic characteristics of a new ACV model should be studied with the PCI method in the steady-state flow mode and in various longitudinal sections of the flow channel. The main result of the study of the flow behind the valve in the steady-state flow mode is the maximum flow rate distribution, which is enough to assess the dependence of the ACV hydrodynamic characteristics on the design features of the ACV model under study. The dynamics of changes in the flow structure during the complete cycle of the valve functioning cannot be obtained by this procedure. Therefore, clinical tests of ACV should be preceded by the study of the hydrodynamic characteristics of ACV in the pulse flow mode.
