We encountered a case of massive tricuspid regurgitation after corrective surgery for a ventricular septal defect. Fixation of the septal leaflet to the ventricular septum at the point where it was closed with a pericardial patch and marked annular dilatation were the lesions contributing to the severe tricuspid regurgitation. The posterior leaflet of the tricuspid valve was excised from the tricuspid annulus, slid to the adhering septal leaflet, and then reattached to a safe area of the septal leaflet to prevent conduction disturbance. The sliding repair was supported by annuloplasty with a Carpentier-Edwards ring, and a concomitant right-sided Maze procedure was conducted for atrial flutter.
