Classic Blalock-Taussig Shunt

A Blalock-Taussig shunt is a surgical procedure that helps improve oxygenation of the blood. It is used in cases of congenital heart defects that cause inadequate oxygenation of the blood (such as single ventricle or tricuspid atresia). This procedure is often used to temporarily until further procedures can be performed to correct the actual heart defect. This procedure can be performed by cutting the subclavian artery and attaching it to the pulmonary artery as a classical Blalock-Taussig shunt. A modified Blalock-Taussig shunt uses a synthetic Goretex graft to connect the subclavian artery and the pulmonary artery.
