Biographical Note for blalock–taussig operation

Blalock

,

Alfred

(1899–1964), and

Taussig

,

Helen B.

(1898–1986), American physicians. Blalock and Taussig were on the staff of Johns Hopkins Hospital. Based upon Taussig's theory that the cause of cyanosis in infants was a functional lack of oxygen, Blalock (a surgeon) developed an operation in which the pulmonary artery and a healthy systemic artery were spliced to bypass any constriction or blockage, thereby giving the lungs sufficient blood for oxygenation. The Blalock-Taussig operation was first performed in 1944; it marked the beginning of modern heart surgery.
