Abstract: The buffalo have belonging to ruminant family. Causality the buffalo has many physiological and anatomical variations with other ruminants. Many different organs of buffalo were studied by different scientists. Some of buffalo organs had distinctive variation and some of it had not variation with another ruminant. The heart is important organ from circulatory system. It has two blood supplies, nutritional and functional. Nutritional blood supply pattern of the heart has variation in different animals. They are mono and bicoronary type. The heart of ruminants has monocoronary type circulation pattern and heart of the horse and human has bicoronary type circulation pattern. In this survey, biometrical characterizes and anatomical structure of buffalo coronary arteries and it branching were studied. Twenty healthy buffalo hearts were collected from Tabriz slaughterhouses and slaughterhouses of another city around Tabriz. Buffalo hearts are used for biometrical studies and studying architecture of coronary arteries. Anatomical structure of buffalo coronary arteries are detected by injection contrast media such as barium sulphate and maglumin and injected by gelatin and latex for determination derivatives branches. Obtained results of this survey are showed that buffalo heart has two coronary arteries. They were right and left coronary artery. Right coronary arteries originated from right coronary sinus and lied in right coronary grove. It was named circumflex branch in this region Then, it was entered in subsinousal groove and extended till apex of the heart. Right coronary artery was named subsinousal interventricular artery in this groove. Circumflex branch and subsinusal interventricular branches had many collateral branches which they supplied the wall of right atrium and right ventricle subsinousal interventricular branch had three large and important collateral branches which they were named ventricular edge, proximal left collateral and distal left collateral branches. Left coronary artery originated from left aortic sinusand passed a short distance and arose 2 branches. They had many collateral branches but two collateral branches were instant and important which they named left proximal and distal collateral branch. Present study results were appeared which buffalo heart was imitating from bicoronary pattern circulation. It was not similar to another ruminant and was similar to horse.
