Still others may want to harken back to the Redbook and reaffirm even more strongly a faith in the need for training students in the philosophy and history of Western Civilization...
...toughness of the human heart and its ability to withstand intrusion had made a deep impression on Brigham Surgeon Dwight Harken during World War II, when he removed shell fragments from servicemen's hearts. His main postwar concern has been with heart valves, especially mitral valves that have been damaged by rheumatic fever. In 1948, he was one of a few bold surgeons who first dared to slip a finger, with a tiny surgical knife at the tip, into a beating heart to separate the leaflets of a mitral valve partly closed by scarring...
...some mitral and aortic valves are so badly damaged and distorted that they are beyond repair. If he could take a piece of metal out of the heart, Harken wondered, why couldn't he put one in? Then he could replace an irreparable valve. When heart-lung machines were perfected, the way was opened for valve replacement. By now.

Into the slit in the aorta wall he stitched a piece of Ivalon sponge, to which the bird-cage valve was attached so that it snuggled into the heart-aorta junction. Mrs. Richardson's tissues grew into the sponge...
