The evolution of surgery in tetralogy of Fallot (TOF) reflects the development of congenital cardiac surgery in general. Initially, TOF surgeries offered palliation: systemic-to-pulmonary shunts that would improve pulmonary blood flow and raise oxygen saturations at the expense of continued cyanosis and a volume load on the left ventricle. Systemic-to-pulmonary artery shunts arising from the subclavian artery (Blalock-Taussig shunts) or aorta (Waterston and Potts shunts) showed very different complications over long-term follow-up. Once cardiopulmonary bypass allowed complete repair of TOF, strategies were developed to optimize different issues that were identified.
