...decide that the answer was yes. Swiftly Dr. DeBakey took one of the two plastic tubes attached to the pump device and stitched it into the hole in the left auricle. Then he took the other tube and sewed it into a hole in the side of the aorta. At DeRudder's chest wall, the round plaque holding these tubes, together with smaller tubes for priming and flushing with saline solution, was attached to a hemispheric chamber 3 in. in diameter. Inside this was a Silastic diaphragm, which alternately generated pressure and exerted suction as it was worked...
...blood from DeRudder's lungs then flowed normally into his left auricle. From there, up to 80% of it was drawn by suction into the pump chamber, held for an instant by a check valve, then pushed by the pressure of the pump's downstroke into the aorta, which supplies all the body's arteries. The rest took nature's course. It passed through the newly implanted artificial mitral valve into the ventricle, which continued to beat, and out into the aorta...
...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 out of six patients, said Dr. Kay, is that the blood vessels borrowed from the lung can be sewn into any part of the heart muscle...
...Walton Lillelehi's team from the University of Minnesota described a similar technique, using part of the network of veins from the patient's own thigh. The trunk vein is sewn into the aorta, and the branches are set in tunnels in the heart-wall muscle-tunnels through which a surgical knife has been run, deliberately cutting several small, transverse arteries, to open them up so that they can receive the new blood supply. Ten of these patients, said Dr. Randolph M. Ferlic, who suffered from crippling angina even when they were sitting down and not exerting themselves...
...Newman and assistant surgeons cut out the clot-plugged section of aorta and replaced it with a Dacron graft. Now Gormley's feet and legs are no longer cold. His blood pressure is down to a healthy 130/80, and last week he was recuperating in Ogden, Utah, taking short walks to rebuild his strength. The man who should have been dead had made medical history. His is the first known case in which such generous collateral circulation compensated for a complete shutdown in the aorta...
