Diagnostic Considerations

Because inadequate collaterals or absent additional sources of pulmonary blood flow may produce hypoxemia too severe for survival for newborn infants with closure of the ductus arteriosus, early recognition of tetralogy of Fallot with pulmonary atresia (TOF-PA) is critical.

Associated syndromes and extracardiac malformations are not uncommon in patients with tetralogy of Fallot with pulmonary atresia (see Etiology). Thus, also consider conditions such as asplenia and polysplenia heterotaxy, double outlet right ventricle with severe pulmonary stenosis or atresia, and single ventricle with severe pulmonary stenosis or atresia.
