[Insertion of prosthetic tricuspid valve two years after the tricuspid valvulectomy].

A case of a 14-year-old boy who underwent a prosthetic tricuspid valve insertion two years after the tricuspid valvulectomy due to intractable right-sided active endocarditis is presented. At the initial operation, the tricuspid valve was thoroughly resected because of marked destruction and attachment of vegetations, and a concomitant ventricular septal defect was directly closed. When a prosthetic valve was placed in the tricuspid portion, a semicircular Dacron patch was attached to the right side of the interventricular septum in a fashion of up-chord and down-arc to cover the bundle of His. The straight edge of the patch was located near the AV node and was not sutured to the tricuspid valve annulus. A 31 mm of CarboMedics prosthetic valve was sutured to the tricuspid valve annulus and to the free edge of the patch at the position near the AV node to prevent AV block. Postoperative course was uneventful and ECG showed regular sinus rhythm.
