want to try to make an artificial one." The first surgeries Two years later, Taussig obtained the collaboration of Johns Hopkins' new chief of surgery Alfred Blalock and his laboratory assistant Vivien Thomas. The three of them developed a surgery now known as the Blalock-Thomas-Taussig shunt. Originally, it was referred to as the Blalock-Taussig shunt: the critical input of Vivien Thomas was overlooked because of his non-academic role and because of his race. Following extensive experimentation on about 200 dogs, on November 9, 1944, Blalock and Thomas performed the surgery on the first human patient. Eileen Saxon, a 15-month-old baby, had arrived at the emergency department earlier that month severely underweight at just 5 kg, purplish blue in colour and hardly able to drink a sip without gasping for breath. Taussig diagnosed her with Tetralogy of Fallot, a diagnosis which meant that without intervention she certainly would not survive to adulthood. The procedure was an immediate success: Eileen's colour quickly returned to normal, she could drink milk more easily and gained a few kilograms. Two months after the surgery she was discharged from hospital. However, she became cyanotic again a few months later and died shortly before her second birthday. Despite Eileen's death, the operation was proof that the Blalock-Thomas-Taussig shunt could in principle be used to extend the lives of children with cyanotic heart disease. By 1945, this operation had been performed on a total of three infants with pulmonary stenosis and pulmonary atresia. As Alfred Blalock and Helen Taussig wrote in Journal of the American Medical Association, "Heretofore there has been no satisfactory treatment for pulmonary stenosis and pulmonary atresia. A "blue" baby with a malformed heart was considered beyond the reach of surgical aid. During the past three months we have operated on 3 children with severe degrees of pulmonary stenosis and each of the patients appears to be greatly benefited. In the second and third cases, in which there was deep persistent cyanosis, the cyanosis has greatly diminished or has disappeared and the general condition of the patients is proportionally improved." Following this report, and lectures given by Blalock and Taussig at conferences around Europe and America, the procedure quickly gained worldwide acceptance. Legacy With the international fame this surgery drew, parents worldwide began coming to Baltimore to have their "blue babies" treated by Blalock and Taussig. The rapid influx of prospective patients was so great
