Coronary arteries of the roe deer (Capreolus capreolus; Linnaeus 1758) heart.
A study of the coronary arteries of the roe deer heart was performed on 21 hearts of animals of both sexes and various ages. The roe deer heart is supplied by two arteries: the left coronary artery and the right coronary artery. The left coronary artery arises from the left aortic sinus and forms a short common trunk. The left coronary artery reaches the coronary groove, then divides into the paraconal interventricular branch and the circumflex branch. The circumflex branch gives off several branches to the left ventricle wall and terminates in the subsinuosal interventricular groove as the subsinuosal interventricular branch. The right coronary artery is less pronounced than the left coronary artery. It arises from the right aortic sinus and enters the coronary groove as the right circumflex branch. We found the left arterial cone branch in 75% and the right arterial cone branch in 80% of the cases investigated. The coronary arteries of the heart run subepicardially. In 9 cases we found muscular bridges over the coronary arteries, mostly on the paraconal interventricular branch. In conclusion we affirm the left type of the arterial vascularisation in the roe deer heart.
