...other dogs, also given heart attacks, to a small, simple pump that is timed by the electrocardiograph. When the heart contracts, the pump is relaxed and actually withdraws a little blood. When the heart relaxes, the pump gets in its "beat"' and forces blood through the aorta into the coronary arteries. After two hours on the pump, five out of these six dogs lived...
Died. Frank Fay, 64, wry stage and screen comedian whose up-and-down career was climaxed by his five-year performance as Elwood P. Dowd, the alcoholic confidant of that invisible, 6-ft. rabbit Harvey; of a rupture of the abdominal aorta; in Santa Monica, Calif. A gentle man of deadly humor (his reply to Milton Berle's challenge to a duel of wits: "I never fight with an unarmed man"), Fay made his first theater appearance at four, by the 1920s had racked up record runs at New York's old Palace Theater, but after a series...
...withdraws blood from the aorta while the heart contracts, lowering the blood pressure within the heart and diminishing the organ's work load. Then, when the heart again relaxes and expands in the course of beating, the blood is swiftly returned to the aorta, restoring normal blood pressure throughout the system...
...patient's chest was opened along the breastbone. Tubes slipped into both great veins led used blood out of her body to the heart-lung machine. Another tube fed it back into a leg artery. A clamp on the aorta helped to keep the heart and lungs virtually bloodless. Dr. Cooley slit open the main pulmonary artery, found nothing in it. But in the successively smaller branches and in the lungs themselves were at least 18 clots. Dr. Cooley pulled some out with forceps, extracted the others with a vacuum suction tube. He washed out the lungs and squeezed...
...lost its momentum, entered the pulmonary vein carrying oxygenated blood from the lungs to the heart's upper left chamber. Car ried along with the blood, the slug went through the mitral valve into the left ventricle and up through the aortic valve. It turned downward at the aorta's arch in the upper chest, and traveled through the femoral artery until this became too nar row. Then the bullet stopped behind the left knee. Surgeons had no difficulty removing it. Military surgeons who treated hundreds of wartime wounded said that the case of Bruce's unguided...
