AFTER nearly a quarter century of relentless work in the surgical laboratory - against overwhelming odds, due in part to the intrinsic nature of the problem and in part to misleading dogmas in existing medical information, Beck and associates have demonstrated beyond any reasonable doubt that alterations of blood flow with measurable dynamics can be produced in the myocardium of the dog, greatly reducing both the mortality and the myocardial destruction resulting from acute obstruction of a major coronary artery.
Some of the specific accomplishments in the surgical laboratory in the study of the coronary circulation, all firsts in the literature on this subject, by Dr. Claude S. Beck and associates are listed as follows:
1. Experimental studies began in 1932 to find direct surgical methods to improve collateral coronary circulation in obstructive diseases of coronary arteries.*
2. Demonstration of arterial extracardiac anastamoses, surgically produced of the caliber of large arterioles
