Patients with TOF can undergo either palliative (shunts) or corrective (intracardiac repair) surgery. Although most children with TOF undergo intracardiac repair as their initial intervention, the principle of shunts remains an important palliative procedure for infants who may not be acceptable candidates for intracardiac repair due to prematurity, hypoplastic pulmonary arteries, or coronary artery anatomy. | Patients with TOF can undergo either palliative (shunts) or corrective (intracardiac repair) surgery.

Shunts are constructed to increase the blood flow to the lungs, to improve the development of the pulmonary arteries. Many patients who underwent intracardiac repair initially had a palliative shunt. Blalock and Taussig first reported successful surgical palliation of TOF in 1945. The procedure, which has since come to bear their names, used a subclavian artery to create an aorta-to-pulmonary artery connection. The technique has been modified and is now usually performed using a Gortex tube to create the connection. | |||
A different type of shunt is the aortopulmonary anastomis, where a direct connection between the descending aorta and left pulmonary artery (Potts) or between the ascending aorta and the right pulmonary artery (Waterston) is constructed. | |||
Intracardiac repair of TOF was reported by Lillehi in 1954. It consists of patch closure of the ventricular septal defect and enlargement of the RVOT. The latter is accomplished by relieving pulmonary stenosis, resecting infundibular and subinfundibular muscle bundles and if necessary by a transannular patch, creating unobstructed flow from the RV into the pulmonary arteries. | Intracardiac repair of TOF was reported by Lillehi in 1954.
