Abstract
Tetralogy of Fallot (TOF) is a heterogeneous congenital heart disease that is occasionally diagnosed during adulthood. However, although they are often asymptomatic, adult patients with uncorrected TOF often have a poor prognosis. Poor outcomes indicate the importance of the identification and management of these patients, especially in the context of intercurrent disease or noncardiac surgery. We describe a case of clinically silent TOF in a 51-year-old woman. TOF was unmasked during a major noncardiac surgery for a polytrauma and successfully treated with the cooperation of a multidisciplinary team. (Level of Difficulty: Advanced.).
