A heart valve prosthesis including a valve body having a first retainer integrally formed with an outer surface thereof. A grafting assembly is formed to include a stiffening member having an axial bore extending therethrough and a second retainer integral with a surface of the stiffening member. The valve body is mounted within the bore of the stiffening member. A retaining member engages the first and second retainers to limit axial displacement of the stiffening member relative to the valve assembly.
