Abstract
Cone reconstruction for Ebstein’s anomaly, although effective, is challenging in neonatal cases. Very few reports have discussed recurrent regurgitation. Herein, we report a successful redo tricuspid valve repair for recurrent regurgitation 5 years after cone reconstruction. A 5-year-old boy underwent cone reconstruction for Ebstein’s anomaly in the neonatal period. Although tricuspid regurgitation reduced initially, it subsequently worsened. The mechanisms of regurgitation are dilatation of the anteroseptal commissure, indentation in the septal leaflet, and foreshortening of the anterior leaflet. Augmentation of the anterior leaflet using an elliptic autologous pericardium and mending of the gaping commissure and indentation markedly reduced the regurgitation.
