Successful replacement of the systemic tricuspid valve with a mechanical valve in a 3-month-old boy with congenitally corrected transposition of the great arteries having a dysplastic tricuspid valve.

There are a few reports of successful replacement of the left-sided systemic tricuspid valve with a mechanical valve in small infants with congenitally corrected transposition of the great arteries having Ebstein's anomaly. Tricuspid valve replacement is the preferred option when pulmonary artery banding, performed as a prelude to performing the double-switch operation, is not feasible because of severe heart failure caused by tricuspid regurgitation.
