...Viet Nam veteran who serves as director of emergency services at St. Mary's Long Beach Hospital in California. "I may open a patient's chest to massage his heart, but it's the cardiac surgeon who is going to put in the plastic aorta. Our job is to keep the patient alive...
...proved to be so diseased that this procedure was not feasible. Garrett, who is now at the University of Tennessee's Medical Unit in Memphis, boldly decided to use a longer piece of vein, also from Hernandez's leg. He ran it from healthy tissue in the aorta directly to an unclogged portion of a major coronary artery-thus bypassing the blockage completely...
Installation of the pump was intricate business. Shanks, who was near death, was wheeled into the operating room at 7:15 p.m. Doctors opened his chest and slit the descending aorta, the downward trunk of the main artery leading from the heart. They then sewed the booster directly into the aorta, led the air hose out through the chest and connected it to the exterior tank. The procedure took five hours, but it was not until 5 a.m. that Shanks left the operating room; Kantrowitz kept him there until he was certain that the booster was doing...
...just that. A regulator unit connected to the heart muscle by wires kept the external pump in phase with the internal organ. As the heart's left ventricle, or major pumping chamber, contracted to force blood through the aorta, the external pump sucked air out of the outer tube, creating negative pressure that helped pull the blood out of the ventricle. Then, as the ventricle relaxed, the pump forced air back into the outer tube, increasing the pressure on the inner passage and forcing the blood through the aorta to the body...
...transplant. It had been tailored to fit, with the bronchi cut short. These were stitched to Herbert's bronchi. The venae cavae, the great veins that return blood to the heart's upper right chamber, were connected, as in an ordinary heart transplant. In like fashion, the aorta was hooked up. It all went "without a hitch," said Barnard...
