[Late diagnosis of tetralogy of Fallot in an asymptomatic adult]. / Tétralogie de Fallot diagnostiquée tardivement chez un adulte asymptomatique.

The authors report a case of Fallot's tetralogy found in an asymptomatic adult patient. Echocardiography and cardiac catheterization confirmed the diagnosis. Life expectancy without surgery is usually short and our patient's survival is therefore uncommon. This case probably represents the oldest patient with uncorrected tetralogy found in the literature.
