| The course of the coronary arteries was studied in marsh deers for comparison with domestic ruminants. The left coronary artery is originated from the aorta in the cardiac auricular surface and divides into paraconal and circumflex branches, which fit the paraconal interventricular sulcus and the subsinuous sulcus, respectively; this artery also gives off a branch to the conus arteriosus just before penetrating the myocardium. The right coronary artery arises from the aorta, in the heart cranial border and ends in this border, close to the subsinuous interventricular sulcus, perhaps without fitting it. |
