Choosing Fortis Memorial Research Institute for Blalock–Thomas–Taussig shunt (BT Shunt) gives patients access to experienced pediatric cardiac specialists, advanced operating facilities, and specialised postoperative cardiac intensive care. Established in 2013, the JCI, NABH, NABL hospital in Gurgaon, India has 311 beds and provides comprehensive congenital heart services.

A Blalock-Thomas-Taussig Shunt (BT Shunt) may be considered when a congenital heart defect causes insufficient pulmonary blood flow and low oxygen levels. The procedure establishes a controlled connection between a systemic artery and a pulmonary artery via a vascular graft, thereby increasing blood flow to the lungs. Doctors evaluate the child's anatomy, oxygen saturation, pulmonary arteries, and overall clinical condition before surgery. After the procedure, close monitoring is required to assess oxygenation, circulation, and shunt patency.
