An apparatus for repairing the function of a diseased valve includes an annular first support member (14) expandable to a first diameter. An annular second support member (16) is spaced axially apart from the first support member and is expandable to a second diameter that is independent of the first diameter. A tubular graft section (18) interconnects the first and second support members. The graft section defines an annulus having a third diameter that is independent of each of the first and second diameters. A prosthetic valve is secured (20) within the annulus of the graft section. The bioprosthetic valve has at least two valve leaflets that are coaptable to permit the unidirectional flow of blood. Methods for repairing the function of a diseased valve and for making the apparatus are also provided.

Un deuxième membre de support annulaire (16) est espacé axialement du premier membre de support et est dilatable jusqu~à un deuxième diamètre indépendant du premier. Une section de greffe tubulaire (18) interconnecte les premier et deuxième membres de support. La section de greffe définit un annulus d~un troisième diamètre indépendant de chacun des premier et deuxième diamètres. Une valve prosthétique est fixée (20) dans l'annulus de la section de greffe. La valve bioprosthétique possède au moins deux valvules qui peuvent être ajustées pour permettre un flux unidirectionnel du sang.
