Fig 1 (A) Step in preparing the composite valved conduit that was used in the primary operation (the original technique) in the case described in the report. A vascular graft 5 mm larger than the labeled valve size is selected and everted at one extremity for approximately 3 cm. The stented bioprosthesis is then placed inside the tube graft and secured to the doubled end of the tube with a continuous polypropylene suture. The everted segment is then pulled down below the valve and beveled as a miniskirt. (B) The polypropylene suture cannot be seen by looking at the upper side of the valve.

Fig 2 (A) Subcoronary implantation of the new biologic valve into the graft. The sewing ring of the valve was fixed with multiple interrupted mattress sutures to the graft, exactly along the prominent suture line (arrow) of the excised bioprosthesis (prosthetic vascular fold).
