Long-term results after surgical correction of Ebstein's anomaly: report of two cases.

Two patients with Ebstein's anomaly had valve replacement with Starr-Edwards cloth-covered valves 11 and 8 years ago. They have been asymptomatic and very active despite the absence of anticoagulation. These cases provide some of the long-term results needed for proper evaluation of the different methods of operative treatment of Ebstein's anomaly.
