Fortis Flt. Lt. Rajan Dhall Hospital provides specialized Blalock–Thomas–Taussig shunt (BT Shunt) with a focus on pediatric cardiac expertise, precise shunt placement, oxygenation support, and comprehensive congenital heart care. Established in 2006, the NABH hospital is located in Delhi, India and operates 162 beds with modern pediatric cardiac infrastructure.

A Blalock-Thomas-Taussig Shunt is an established palliative surgical technique used to provide pulmonary blood flow in selected children with cyanotic congenital heart disease. During surgery, a conduit is positioned between a systemic artery and the pulmonary artery, allowing oxygen-poor blood to reach the lungs for oxygenation. The procedure does not correct the underlying heart defect and is commonly used as part of a staged treatment strategy. Detailed preoperative cardiac assessment and intensive postoperative monitoring help guide care and identify potential complications.
