Aortic root replacement with a valved conduit containing a stented xenograft.

The Bentall operation is a well-established procedure for aortic root replacement, generally contemplating the use of a mechanical valve substitute. We have devised a simple modification by which a stented bioprosthesis is sutured inside, rather than at the extremity, of a vascular tube graft. This facilitates the technique of implantation and may simplify a redo procedure in case of valve failure.
