Gropius, one of the nation's leading architects, died at the Tifts-New England Medical Center last Saturday as the result of complications following surgery undergone to replace the aortic valve of his heart...
...Surgeon General's report. Based on a review of more than 2,000 research studies made in the past three years, the report repeats that cigarette tars can cause lung cancer; it depressingly documents further evidence that the weed can bring on peptic ulcers, aortic aneurysm, cancer of the larynx, mouth, pharynx, esophagus and bladder. A two-pack-a-day smoker aged 55 to 64, says the report, has 34 times more chance of dying of lung cancer than a nonsmoker. But an equally grave danger may be coronary heart disease caused by the massive doses of nicotine...
...balloon in place, the ECG signals were fed into a relay to regulate the pump's timing. When the patient's left ventricle contracted naturally, it sent a modest amount of blood into the aorta, but under insufficient pressure. A fraction of a second later, when her aortic valve had closed, the ECG signal made the pump fill the balloon with helium. This forced the blood in the aorta not only up and down, but also back to the roots of the coronary arteries, thus increasing the oxygen supply to the heart muscle. Meanwhile the ventricle relaxed...
...Vincent Charity Hospital he had recently set up a bank of human heart valves removed from accident victims and waiting to be used in an ingenious manner developed by his associate, Dr. Akio Suzuki. Because mitral valves have proved unsatisfactory for transplants, Dr. Kay selected an aortic valve from the bank, turned it upside down so that it would permit blood flow in the proper direction, and stitched it in place. There was little danger of transplant rejection, because heart-valve tissue has a negligible blood supply. Last week, two months after her operation, Mrs. Wilmer used the most familiar...
