Congenitally corrected transposition of the great arteries in a patient with cor triatriatum: a rare combination.

Congenitally corrected transposition of the great arteries is a rare anomaly that is thought to arise from a defect in looping of the primitive cardiac tube. Cor triatriatum is another rare congenital cardiac anomaly due to faulty incorporation of the common pulmonary vein into the left atrium. We present a rare case comprising both disorders in one patient.
