The Blalock–Thomas–Taussig shunt (BTT shunt), [1] previously known as the Blalock–Taussig Shunt (BT shunt), [2] is a surgical procedure used to increase blood flow to the lungs in some forms of congenital heart disease [3] such as pulmonary atresia and tetralogy of Fallot, which are common causes of blue baby syndrome. [3]
The most common shunts are the Modified Blalock Taussig shunt (MBTS) or right ventricle- to pulmonary artery shunt (RVPA or Sano shunt). Most patients who undergo a Norwood procedure will proceed to further stages of single ventricle palliation. A second surgery, also known as the Glenn procedure, occurs at 4–6 months
First operation: modified Blalock-Taussig shunt to maintain pulmonary blood flow by placing a Gore-Tex conduit between the subclavian artery and the pulmonary artery. See also Norwood procedure. Where too much flow to the lungs is present, a pulmonary band may be placed in a first operation.
The Mustard procedure was developed in 1963 by Dr. William Mustard at the Hospital for Sick Children. It is similar to the previous atrial baffle used with a Senning procedure , the primary difference being that the Mustard uses a graft made of Dacron or pericardium , while the Senning uses native heart tissue.
The surgery had been designed and first performed on laboratory dogs by Thomas, who taught the technique to Blalock. Although Thomas perfected the technique, he could not perform the surgery because he was not a doctor. The surgery was not completely successful, since Eileen Saxon became cyanotic again a few months later. Another shunt was ...

Retrospective reviews demonstrate failure of the procedure in 6.5% of patients. Reported mortality related to the BDG procedure ranges from 0.7% to 2.4%, however up to 71% of patients may die once the BDG shunt fails, with many decompensating before further surgery can be performed.
