An improved implantation holder apparatus and system for holding bioprosthetic aortic valves for insertion into a heart. The handle system interacts with implantation holder and the valve in such a way that commissure support struts may be retracted by simply rotating the handle which allows the surgeon more room to work in tight quarters to complete the implantation process. Included is a handle system, which can be attached and detached, for securing the holder during application of the parachute stitching and moving the valve into position. Once the valve is in position, the handle may be retained in place, or removed for greater ease of access to the aortic cavity.
