A surgically created connection between a systemic artery and the pulmonary artery (PA) is termed a systemic-to- pulmonary artery shunt or, more commonly, a BT shunt (after Blalock and Taussig, the first physicians to describe the connection). Many consider the description of this procedure, in the Journal of the American Medical Association (JAMA) in 1945, to have revolutionized the field of pediatric cardiology (Blalock, 1945).
Palliative surgery increases pulmonary blood flow, temporarily stabilizing the patient and allowing him or her to undergo a future corrective or palliative procedure. Thus, the purpose of the surgically created systemic-to-pulmonary artery shunt is to increase pulmonary blood flow in the interim prior to definitive (ie, anatomic) reconstruction.
