Detachment of the anterior leaflet of the tricuspid valve to expose perimembranous XXXX .

BACKGROUND: Detachment of the septal leaflet of the tricuspid valve has been described for better access to perimembranous @entity1757 . Detachment confined to the anterior leaflet is less known, although it provides a better exposure of the subaortic area and puts less jeopardy on the conduction tissues. METHODS: Data regarding 49 consecutive @entity1 who had congenital perimembranous @entity1757 closure were retrospectively reviewed. Thirty-three @entity1 (67%) underwent temporary detachment of the anterior leaflet of the tricuspid valve. The defect was closed with a Gore-Tex patch and a continuous suture. In 10 @entity1 (29%), concomitant right ventricular outflow tract enlargement was performed. Follow-up was obtained in every @entity1 (median time, 11 months; range, 2 to 26 months). RESULTS: No early or late @entity204 occurred. Closure of the @entity1757 was complete, with no more than trivial residual jet leaks found in perioperative echocardiography. All @entity1 were in sinus rhythm. The tricuspid valve never showed more than mild insufficiency after repair. No @entity1 showed @entity3888 . CONCLUSIONS: Detachment of the anterior leaflet of the tricuspid valve to expose the @entity1757 is a safe approach that allows rapid closure of the defect with a continuous suture and provides excellent results.
