OPERATIONS FOR CORONARY ARTERY DISEASE

AMA Arch Surg. 1955;70(1):143-153. doi:10.1001/archsurg.1955.01270070145026
Abstract

DURING the past 20 years, approximately 4,000 experimental operations were carried out in the laboratory of Dr. Claude S. Beck on the coronary blood supply in dogs. The coronary vessels were dealt with directly, yielding information that could not be obtained in any other way. This experimental work made it possible to establish certain facts. Two operations for coronary artery disease, the Beck I and Beck II, are based upon these facts. The human figure symbolizes over 186 patients with coronary disease that have been operated on. To the right of the figure is a human heart embedded in plastic. A Beck II operation had been performed on the heart. The dog drawing symbolizes over 4,000 dogs operated on in the experimental laboratory. Above the drawing is a dog heart embedded in plastic. A Beck II operation had been performed on the heart.
