Scimitar syndrome in an older adult.

Scimitar syndrome is a rare congenital heart disease. It is divided into subgroups of infantile, adult, and multiple cardiac and extracardiac malformation. Most patients are diagnosed during infancy and occasionally in adolescence, but very few patients are older than 20 years of age, and only some cases have severe symptoms that require surgical correction. We report a case of a man 54 years of age who was diagnosed with asymptomatic scimitar syndrome with insignificant left-to-right shunt (Qp/Qs = 1.51) with a medical history of type 2 diabetes mellitus and hyperlipidemia. Related literature on scimitar syndrome, particularly on older adults, is also reviewed.
