Experimental study of myocardial bridges.
Myocardial bridges were reproduced in dogs by transfer of a fragment of the left ventricular wall above the upper portion of the anterior interventricular artery. The viability of this bridge was shown by coronarography, anatomic, histologic and electron microscopic studies, illustrating the vascular patency and the integrity of blood vessels and neighbouring myocardium in the cases postoperatively heparinized. The experimental model efficiency was also proved by ECG examinations revealing ischemic distresses induced by compression of the bridge against the underlying artery.
