A device for engaging a heart valve prosthesis during implantation includes a mechanism for attaching the device to the heart valve prosthesis. The heart valve prosthesis includes a circular valve body having an annulus with a substantially annular aperture therein. At least one movable occluder is carried in the annulus and is movable between an open position and a closed position. The occluder is carried on a strut coupled to a valve body. The attachment mechanism includes a member which couples to the strut, thereby affixing the device to the heart valve prosthesis. The attachment mechanism may be actuated to disengage the heart valve prosthesis.
