By injecting the coronary arteries in common breed dogs of various ages, we have underlined certain modifications concerning the path, the caliber and the structure of the cardiac vessels. In this paper we will refer exclusively to the anatomical aspects of these vessels. In young subjects, both the cardiac arterial trunks and their branches present in general well traced paths, without changes in the arterial walls. Compared to this situation, in aged animals, we have both anatomical modifications of vascular paths and of their lumen’s caliber, as well as the varicose aspect of their walls. These morphological aspects also imply alterations of the differentiated vascular perfusion of the myocardium, while facilitating clinical interpretation in canine cardiac pathology.
