context_page_description: The Blalock–Thomas–Taussig shunt is a surgical procedure used to increase pulmonary blood flow for palliation in duct dependent cyanotic heart defects like pulmonary atresia, which are common causes of blue baby syndrome. In modern surgery, this procedure is temporarily used to direct blood flow to the lungs and relieve cyanosis while the infant is waiting for corrective or definitive surgery.One branch of the subclavian artery or carotid artery is separated and connected with the pulmonary artery. The first area of application was tetralogy of Fallot.The Blalock–Thomas-Taussig shunt is used in the first step of the three stage palliation.
