Primary correction in infants is the ideal operation for treatment of tetralogy of Fallot (TOF), and it is usually performed under cardiopulmonary bypass (CPB). The aims of the surgery in this population are to close the ventricular septal defect (VSD), resect the area of infundibular stenosis, and relieve the right ventricular (RV) outflow tract (RVOT) obstruction.

Before cardiopulmonary bypass is initiated, previously placed systemic-to-pulmonary artery shunts are isolated and taken down. Patients then undergo cardiopulmonary bypass. Associated anomalies, such as atrial septal defect (ASD) or patent foramen ovale (PFO), are closed.
