Etienne-Arthur Louis Fallot and his tetralogy

Étienne-Arthur Louis Fallot (1850-1911) is one of the most significant medical figures of the 19th century with an eponymous congenital cardiac malformation. His initial account of the four anatomical features making up his tetralogy proved remarkably significant in the progression of clinical descriptions of the lesions producing cyanotic congenital cardiac disease. Although subsequently the cause of appreciable controversy, the accuracy of his initial descriptions underscore the current diagnostic and therapeutic approach to the malformation now known uniformly as tetralogy of Fallot.
