This study evaluated the distribution and possible variations of the coronary arteries and the presence of myocardial bridges in dairy cattle from Northeastern Brazil. Thus, healthy hearts were analyzed according to many variables. Left coronary artery originate the rami paraconalis, circumflexus et subsinuosus. Ramus subsinuosus and right coronary artery showed a short subepicardial path. Lengths of the main branches showed statistical differences only in relation to age group and weight of the animal. Myocardial bridges had a prevalence of 55% and were more frequent over the ramus paraconalis. Veterinary medicine is able to provide experimental models to expand the necessary study to understand pathophysiology and clinical relevance of the bridges.
