Diagnosis of a congenitally corrected transposition of the great arteries in a 50-year-old multiparous woman.

Congenitally corrected transposition of the great arteries (cc-TGA) is a rare congenital heart disease. In the literature, few patients with this anomaly have been reported to be asymptomatic until after the fifth decade. We describe a 50-year-old female with five pregnancies and successful deliveries, who was unrecognised until late in her fifth decade.
