Though there is still a long way to go. progress to date has been impressive. In 1946. Montreal Surgeon Arthur Vineberg, figuring that the internal mammary artery (see diagram) is dispensable, carefully cut it away from the breastbone, left its upper end in place, and implanted its lower end in the left ventricle, the heart's primary pumping chamber. A decade later, Dr. Charles P. Bailey, then in Philadelphia, developed a procedure called endarterectomy, in which he opened a blocked coronary artery and reamed out a plug of accumulated cholesterol with a device resembling a crochet hook...
...arteries. The dye, which showed up clearly on motion picture X rays, made it possible for physicians to see with 90% accuracy exactly where the coronary arteries were blocked. The Sones method also enabled cardiologists to evaluate the results of their operations and proved beyond any doubt that the Vineberg implant measurably improved circulation of blood to the heart muscles...
...oldest of these, pioneered 30 years ago by Cleveland Surgeon Claude S. Beck, involves opening the heart sac and scratching the heart's surface, so that in self-defense it builds up an increased blood supply. A second technique devised by Montreal's Dr. Arthur Vineberg requires ihe freeing of minor arteries in the chest and implanting these in the heart muscle.* More radical is the removal of a pie-cut wedge of damaged heart, after which the edges of healthy muscle are stitched together. There are, in addition, several methods of reaming atherosclerotic plugs from coronary arteries...
...Variations of the Vineberg operation are now the commonest form of adult heart surgery in the U.S. and Canada, with almost 2,000 performed annually...
Muscle Tunnel. Research surgical teams from two major medical centers told the College of Cardiology about new techniques based on the Vineberg principle but using different vessels to carry blood to the heart muscle. Cleveland's Dr. Earle B. Kay reported that he and Dr. Akio Suzuki cut out a piece of the left lung's arterial network with "a multitude of side branches," and sew the "trunk" end into the descending aorta. Then they implant the smaller branches in the heart muscle. The advantage of this method, which has so far been successful in four...
