...hospital by ambulance. Emergency room physicians stabilized his condition and transferred him to a special laboratory for a delicate experimental procedure. A long, thin plastic tube was inserted into an artery in his leg and gently pushed through the blood vessels all the way up into the aorta to the coronary arteries. A radiopaque substance was injected into the coronary vessels, and X-ray pictures were taken, revealing a blood clot. Doctors infused an anticlotting drug through the tube. Within an hour, the clot had dissolved, blood flow was reestablished, and Clendenen was spared extensive heart damage...
...according to some researchers, is a device that could take over temporarily for either of the two main pumping chambers of the heart, particularly the workhorse left ventricle. These assist devices shunt blood from the ventricle to a pump outside the body that sends it directly to the abdominal aorta or femoral artery to continue its natural circulation. The heart is left intact but goes on a sort of holiday, rebuilding its strength so that it can later resume its full work load. Says John C. Norman of the Texas Heart Institute in Houston, who has been working on left...
...most familiar advance dates from 1967, when surgeons performed the first bypass operation on a patient with a coronary artery blockage. In the procedure, a vein taken from the patient's leg is grafted to the aorta and to the unobstructed portion of the coronary artery, thus detouring blood around the blocked area...
...patient was Mary Gohlke, 45, a newspaper executive from Mesa, Ariz. She had been suffering from pulmonary hypertension, a condition in which high blood pressure in the vessels of the lungs impairs breathing and eventually damages the heart. Dr. Bruce Reitz and his Stanford team severed the aorta and trachea and cut through the heart's right atrium to remove the heart and lungs. "The whole thing comes out as a package," explains Reitz. Then they replaced it with healthy organs from a 15-year-old boy killed in a car accident...
...only a few yards away. One shattered the two joints of the ring finger of his left hand, ricocheted and grazed his right arm. The other blasted into his abdomen, passing completely through his body and ripping up the Pope's intestines but narrowly missing his pancreas, abdominal aorta and spine. For 5 hr. 25 min., as rumors flew around the world and hospital patients in bathrobes mingled with Italian dignitaries and journalists to exchange shocked speculation, surgeons labored to take out several pieces of the Pope's intestine and perform a colostomy, which would remove wastes outside...
