Abstract


Myocardial bridges were found in 90% of dissected adult hearts of thedromedary camel. Myocardial bridges were classified into two types according to their relation with the overbridged artery. In Type I, the descending interventricular subsinuosal or paraconal branches were bridged by one or two bands of cardiac muscle, in Type II, the descending interventricular subsinuosal or paraconal branches were noticed to dip in the myocardium without reappearing. Eight out of eleven hearts of fetuses had myocardial bridges (72.7%); seven hearts had myocardial bridges of Type II category in the subsinuosal interventricular branch, (87.5%); only one heart showed myocardial bridges on both sides (12.5%). In this heart, Type I category was observed over the subsinuosal interventricular branch whereas Type II category was confined to the paraconal interventricular branch.
