Fallot’s original description of the pathologic anatomy of TOF is as follows: a true pathologic anatomic disease consisting of four lesions: (1) pulmonary stenosis; (2) septal traffic; (3) rightward deviation of the origin of the aorta; and (4) hypertrophy of the right ventricle almost always. Sometimes there is an unclosed foramen ovale. Fallot, who presented tetralogy with full reading and reference to previous work, humbly stated that “this interesting cardiac peculiar lesion has all been encountered and fully described before.” He believed that the entire lesion was due to pulmonary stenosis. He also believed that the pulmonary stenosis was the result of a developmental disorder of the pulmonary valve and funnel section during fetal life. This is similar to the modern theory of Vann Praagh, but differs from Anderson’s theory. Fallot’s achievements were not well known at the time of his death. He himself was suffering from illness and died in May 1911 at the age of 61. He was a “purifying loneliness”. He was an amazing scholar! As long as mankind exists, as long as this disease exists, Fallot will be immortalized! In 1988, 100 years after Fallot’s systematic introduction of TOF, Eur J Cardio-thorac Surg published a translation of the original text in English in honor of this great medical man
