...Mason Sones Jr., a Cleveland cardiologist who in 1958 developed a method of mapping the cardiovascular system. Known by the jawbreaking name of cine coronary angiography, Sones' technique involved inserting a catheter, or thin piece of tubing, into an arm artery, guiding it up through the aorta and then squirting a radiopaque dye through it directly into the coronary 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...
...study coronary-artery disease. In an operation first performed four years ago next week, he removed a section of his patient's saphenous vein, attached one end to the blocked right coronary artery at a point below the obstruction, stitched the other to a spot on the aorta above the blockage. The procedure allowed blood to bypass the blockage and greatly improved the heart's blood supply...
...both a doctor and a priest. Abbe Claude Jaugey, the De Gaulles' family priest, found the general in "great pain." While the last sacraments were being administered, De Gaulle sank into unconsciousness. Shortly after Dr. Guy Lacheny arrived, he was pronounced dead of a massive rupture of the aorta...
These conclusions are supported by the British Medical Journal, in which surgeons describe four auto-accident cases seen at Harefield Hospital in Middlesex. In two of them the aorta was ruptured; in one, the injury was to the mitral valve, and in one the septum (wall) between two of the heart's chambers was torn. Only a decade ago, there would have been little hope for the victims, but that is no longer true. In all four cases surgery was successful-including two instances in which the aorta was patched with a Dacron graft...
That, in the opinion of the University of Rochester's Dr. Robert M. Greendyke, is long enough for the huge forces that result to cause the inner lining of the aorta to rupture and balloon out into an aneurysm, or to be virtually sheared off at a point such as its isthmus immediately below the arch...
