The “Blalock-Taussig operation” for the relief of congenital defects of the pulmonary artery, Tetralogy of Fallot ("blue baby syndrome").

"The first surgical repair was carried out in 1944 at Johns Hopkins.^[70] The procedure was conducted by surgeon Alfred Blalock and cardiologist Helen B. Taussig, with Vivien Thomas also providing substantial contributions and listed as an assistant.^[3] This first surgery was depicted in the film Something the Lord Made.^[59] It was actually Helen Taussig who convinced Alfred Blalock that the shunt was going to work. 15-month-old Eileen Saxon was the first person to receive a Blalock-Thomas-Taussig shunt.^{[59]" (Wikipedia article on Tetralogy of Fallot).}
