History – The classic description of the tetrad was actually first described in 1672 by the Danish physician and anatomist, Neils Stenson (1638-1686).  The namesake of this condition is Etienne-Louis Arthur Fallot (1850-1911), who was a French physician.  He described the tetrad in 1888 using previous observations and building from the work of Stenson, but garned little contemporary appraise.  It wasn’t until 1931 when Fallot’s work was rekindled and translated by Dr. Paul Dudley White.
