STUDY OF FUNCTIONAL FEATURES OF DIFFERENT TYPES OF BIFURCATIONS OF THE INTRAORGANIC ARTERIAL BED OF THE HEART BY MATHEMATICAL MODELING

The aim ofоuman heart by virtually testing their digital models based on the results of morphometry.
Material and methods. Using the ANSYS and Vasculograph computer programs, the conductive, distributive and supporting functions of digital models of bifurcations of the intraorganic arterial bed of different types were studied: the first, the value of the internal diameter of the proximal segment (D) is less than the sum of the internal diameters of the distal segments (dmax and dmin), D < dmax + dmin; zero, D = dmax + dmin; the second, D > dmax + dmin. Digital models of bifurcations of different types were constructed on the basis of a previously conducted morphometric study of corrosion preparations of the bed of the intraorganic coronary arteries of the heart.
Results. In the course of a virtual study of the functional features of digital models of different types of bifurcations of the intraorganic arterial bed of the heart, it was found that different types of bifurcations participate to an unequal extent in the performance of conductive, distributive and supporting functions; the main role in the performance of these functions belongs to bifurcations of the 1st type, in which the value of the internal diameter of the proximal segment (D) is less than the sum of the internal diameters of the distal segments (dmax and dmin), D<dmax+dmin.
Conclusion. As a morphometric standard of the normal structure of the intraorganic arterial bed of the heart, it is possible to use the quantitative ratio of bifurcations of different types.
