Abstract:
Introduction: Despite the long history of the study of the heart as the central organ of cardio -
vascular system, the problems associated with the pathology of coronary arteries (CA) and their branches
do not lose their relevance to this day. For many years, the focus was research CA, in various pathologies,
the results of which do not provide a complete picture of architectonic features and morphometric
characteristics. Equally important is to determine the blood supply of the heart (TBSH). The classical
definition of TBSH describes exclusively anatomical features architectonic vessels and does not give the
amount of blood flowing through the vessels and the blood supply to the area. "White Spots" to explore
issues underscore the urgency of research topics in theoretical and clinical relationships.
Purpose and objectives: To determine the particular variant anatomy and subepicardial vascular branching CA, as well as mathematically calculated based on the type of blood supply to the morphometric data.
Subjects: 58 human heart preparations of both sexes. Methods: Makrodissection, mikrodissection, morphometry, the statistical method, mathematical modeling.
Results: During the study it was found that the left coronary artery (LCA) has three options
architectonics: typical - bifurcation, with the division into two branches (anterior descending branch
(ADB) and the circumflex branch (CB) - 75%), trifurcation (ADB, CB and left marginal branch
(LMB) - 23%), kvadrifurkatsiya (ADB, CB, LMB and branch cone (BC) - 2%).
ADB for the anterior interventricular sulcus also has 3 options architectonics: 1 - reaches apex of the heart - 55 % 2 - disappears between the middle and lower third of the anterior interventricular
sulcus - 15 % 3 - goes around the top of the heart and extends into the lower third of the posterior
interventricular sulcus - 30 %.
As well, we have developed an algorithm of actions and calculations, allows us to calculate
TCS from a mathematical point of view, given the above mentioned morphometric parameters.
Conclusion: The method proposed for the detenuination o f blood supply with the help of
mathematical calculations, to determine the TBSH based not only on the anatomical structure as
well as on the morphometric parameters of the heart.
Data on structural - functional organization and topographic - anatomical relationships VA
obtained using modern research techniques, including computer programs, can be used in anatomy -
in particular, in addition to the guidelines, as well as in cardiology and cardiac surgery.
