Fig 1 Schematic drawings of a novel technique of supra-annular mitral valve replacement. (A) The valve metal housing was inserted into the short-segment polytetrafluoroethylene (PTFE) tube graft, which was then attached to the sewing ring of the valve with a continuous PTFE suture. (B) The outflow margin of the PTFE tube graft was then threaded onto the valve sutures (B, C) and short longitudinal incisions were made in the PTFE tube graft between the two limbs of each mattress suture to allow the tube to conform to the smaller annulus as the sutures were tied.
