title: Surgical correction of tetralogy of Fallot (TOF) after palliative operations.
abstract: Patients with tetralogy of Fallot and unfavorable anatomy of the right ventricular outflow tract or hypoplastic pulmonary arteries may require primary palliation and subsequent repair (two-stage repair). The concept of palliation includes improvement of the lung perfusion and relief of systemic hypoxia by means of some type of arteriopulmonary arterial shunt or a Brock-type operation. At repair a previously constructed aorto-pulmonary anastomosis has to be closed, which can be done without increased risk for hospital death or postoperative morbidity.
