Experimental surgical treatment of occlusive coronary artery disease: I. Use of pedicled pectoral muscle grafts

1. A technique for the performance of cardiomyopexy between a pedicled pectoral muscle graft and the left ventricular myocardium is presented. 2. The retrograde circumflex coronary artery blood flow in this group of animals averaged 5.4 cc per min., which represented a threefold increase over the expected normal value. 3. By perfusing the arch and descending aorta with Neoprene Latex, the coronary arterial tree could be filled despite the fact that the material could not enter through the normal coronary ostia. 4. Because of the demonstration that the coronary arteries could be filled through an extracoronary source, it is believed that this procedure warrants further investigation.
