[Arthur Fallot (1850-1911) and blue disease].

Arthur Fallot (1850-1911) described for the first time the so-called "maladie bleue", or "blue disease". His discovery was published in Marseille Médical, and therefore remained little known. Present cardiologists know what they owe him and therefore call "tetralogy of Fallot" this congenital heart condition.
