Ventricular structure and function after radical correction of the tetralogy of Fallot.

Abstract
The over-all results of radical correction of the tetralogy of Fallot in 133 patients were presented briefly. Although initial mortality was high, it subsequently fell to 19% in 56 patients operated upon. The long-term prognosis in the majority of patients is excellent despite the presence of the ventriculotomy scar and right bundle-branch block. The prognosis is less certain for the minority who are left with important residual lesions.
