Prosthetic valve replacement in Ebstein's malformation: 30-year follow-up.

This report addresses a 42-year-old asymptomatic patient who underwent prosthetic replacement of his tricuspid valve 31 years previously for Ebstein's malformation. A ball valve prosthesis was implanted to replace the abnormal valve. Furthermore, he had concomitant closure of a large atrial septal defect with a perforated patch together with plication of the atrialized ventricular segment. The patient is asymptomatic, and it remains noteworthy that he has not been on coumadin for about 30 years.
