In this study, myocardial bridges in the hearts of various domestic animals were described and classified by means of macroscopical and microscopical observations. In the classification of the bridges, special attention was given to the location, width and thickness of the bridge. In microscopical observations in the bridges were classified by regarding the number of the comminant veins of the overbridged artery.

As a material, 15 Akkaraman sheep, Angora goats and cattle, 8 dogs and Water buffalo hearts were used.

In all hearts of the various domestic animals species investigated in this study, the myocardial bridges were observed macroscopically on the ramus interventricularis paraconalis and subsinuosus, on the first grade ramus of a ramus interventricularis and on the second grade ramus of a ramus interventricularis.

In microscopical observations, the myocardial bridges were classified into three groups. These were the bridges with no commi tant vein, the bridges with one commitant vein and the bridges with two commitant veins.
