Right coronary artery of the German Shepherd heart

Abstract

Knowledge of basic veterinary disciplines such as animal anatomy and physi- ology is essential for the practicing veterinary professional. It is important to take into ac- count not only the features of the morphology of the species of the animal, but also the breed and age patterns of the structure of various organs and systems. The purpose of our study is to study the anatomical and topographic patterns of the structure of the branches of the right coronary artery of the heart in German shepherds that have reached physi- ological maturity. The object of the study was ten corpses of German shepherds aged 18- 24 months, which have reached physiological maturity. The work was carried out at the Department of Animal Anatomy, St. Petersburg State University of Veterinary Medicine. The methods for the study were: fine anatomical preparation, the manufacture of corrosive preparations and photography. According to the results of the study, it was found that the right coronary artery in the German Shepherd is underdeveloped, which corresponds to the classification and confirms the left-coronary type of blood supply to the heart in dogs. The subsinusoid artery in the German Shepherd belongs to the left coronary artery, and the right coronary artery does not reach this region. The right conical branches, as well as the right anastomotic and right terminal branches, form anastomoses with the branches of the left coronary artery, that is, close the collateral blood supply pathways and reduce the risk of coronary heart pathologies. The right coronary artery in the studied German Shepherds does not supply blood to the interventricular and interatrial septa.
