Asan Medical Centre 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 1989, the ISO hospital is located in Seoul, South Korea and operates 2700 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.
