For patients with hypoplastic left heart syndrome (HLHS), it is essential to control moderate to severe tricuspid regurgitation (TR) so that the Norwood procedure can be tolerated. Because of the vulnerability and future growth potential of the valve leaflet, it is difficult to adopt a conventional procedure for immobilizing the leaflets and annulus. We report here a case in which we used the interannular bridge technique to control central TR in an infant with HLHS who had undergone the Norwood procedure.
