[Radical correction of tetralogy of Fallot after palliative operations]

The experience in radical correction of tetralogy of Fallot in 120 patients after various palliative operations is generalized. Twenty-five patients (20.8%) died. From comparative evaluation of the different preceding operations, preference cannot be given to any of the anastomoses. From the standpoint of the subsequent radical correction, Potts' anastomosis is the most disadvantageous palliative intervention.
