A replacement heart valve and fixture assembly for limiting longitudinal stretch during fixation of a harvested aortic root including valve leaflets. The assembly includes an inflow plug inserted into the inflow section of the aortic root and having an apertured tube or cannula extending through the valve leaflets to an outflow plug inserted into the outflow section of the aortic root. Apertures in the tube are located on either side of the valve leaflets and the tube is coupled to a fluid inlet, preferably located on the outflow plug. The outflow plug is slidable relative to the tube and is provided with an engagement mechanism such as a setscrew for fixing the location of the outflow plug relative to the tube and the inflow plug. |
