At NMC Specialty Hospital Al Salam, Blalock–Thomas–Taussig shunt (BT Shunt) is performed using advanced pediatric cardiac surgery techniques and individualized treatment plans based on the child's heart defect and pulmonary blood flow. Established in 1999, this CBAHI hospital in Riyadh, Saudi Arabia has 100 beds and provides comprehensive congenital heart disease services.

A BT Shunt may be recommended for selected infants and children with congenital heart defects in which blood flow to the lungs is significantly reduced. During the procedure, a synthetic vascular graft is placed between a systemic artery and the pulmonary artery to provide an alternative route for blood to reach the lungs. The shunt is generally used as part of staged treatment rather than as a definitive repair of the underlying heart defect. Careful postoperative monitoring helps assess oxygenation and shunt function.
