15-month-old Eileen Saxon was the first person to receive a Blalock–Thomas–Taussig shunt. Furthermore, the Blalock-Thomas-Taussig procedure, initially the only surgical treatment available for tetralogy of Fallot, was palliative but not curative. The first total repair of tetralogy of Fallot was done by a team led by C. Walton Lillehei at the University of Minnesota in 1954 on an 11-year-old boy. Total repair on infants has had success from 1981, with research indicating that it has a comparatively low mortality rate. Today the adult TOF population continues to grow and is one of the most common congenital heart defect seen in adult outpatient clinics. : 100–101

Related disorders
The following illnesses have symptoms that are comparable to tetralogy of Fallot. For a differential diagnosis, comparisons between these disorders provides valuable knowledge. Atrial septal defects
Atrial septal defects (ASDs) are a kind of congenital heart abnormality in which a tiny opening exists between the two atria of the heart. The burden on the right side of the heart is increased as a result of these abnormalities, as is the blood flow to the lungs. This leads to excessive blood flow to the lungs and an increased workload on the right side of the heart. Another common finding associated with ASDs is right ventricular hypertrophy, also known as enlargement of the right ventricle. Ventricular septal defects
Ventricular septal defects (VSDs) are a kind of congenital heart abnormality in which one of the ventricles is missing. Two atria and one big ventricle are common in infants with congenital abnormalities.
Toxic and nutritional optic neuropathy is a group of medical disorders defined by visual impairment due to optic nerve damage secondary to a toxic substance and/or nutritional deficiency. The causes of these disorders are various, but they are linked by shared signs and symptoms, which this article will describe. In several of these disorders, both toxic and nutritional factors play a role, acting synergistically. Signs and symptoms
Vision loss in toxic and nutritional optic neuropathy is bilateral, symmetric, painless, gradual, and progressive. Dyschromatopsia, a change in color vision, is often the first symptom. Some patients notice that certain colors, particularly red, are less bright or vivid; others have a general loss of color perception. Loss of visual acuity may start with a blur or haze at the point of fixation, followed by a progressive decline. The degree of vision loss can extend to total blindness, but a loss beyond 20/400 is rare, except in the case of methanol ingestion. Peripheral vision is usually spared since the pattern of loss typically involves a central or cecocentral scotoma, a visual field defect at or surrounding the point of fixation. This pattern can be revealed via visual field testing. Upon examination, the pupils usually demonstrate a normal response to light and near stimulation. In those who are practically blind, the pupils will be dilated with a weak or absent response to light. The optic disc may appear normal, swollen, or hyperemic in early stages. With hyperemia, disc hemorrhages may also be present.
