Right Coronary artery of the heart of Maine coon cat

Abstract

The study of the arterial bed of the heart of small domestic animals is of high practical importance in veterinary practice and requires further development and study. The work was performed at the Department of Animal Anatomy, St. Petersburg State University of Veterinary Medicine. The material for the study was five corpses of Maine Coon cats, of which three cats (male) and two cats (females).The methods for the study were fine anatomical preparation and making casts of heart vessels using Flexstep latex milk. According to the results of the study, it was found that the right subsinus artery in a Maine Coon cat is poorly developed and does not participate in anastomosis with the branches of the left paraconal artery in the region of the apex of the heart. In the region of the coronary sulcus, the right anastomotic branch departs from the right coronary artery, which is involved in closing the collateral path of blood supply to the heart of the Maine Coon cat. The blood supply to the heart of a Maine Coon cat is due to the right and left coronary arteries, but the right coronary artery and its branches are less developed compared to the left, which confirms that this cat breed has a left-coronal type of blood supply.
