Claim Text:
1. A method for implanting a prosthetic mitral valve with reduced suture entanglement, the method comprising: threading an array of implantation sutures through a sewing ring of a prosthetic mitral valve mounted on a packaging system including a valve holder and a commissure constriction rod extending through the valve holder, wherein the valve holder is attached to the sewing ring, the commissure constriction rod is positioned with a distal end thereof holding a trefoil arrangement of attachment sutures in a tented arrangement, thereby pulling valve commissures of the prosthetic mitral valve radially inwards and reducing entanglement between the implantation sutures and the valve commissures; parachuting a prosthetic mitral valve along an array of implantation sutures until the sewing ring contacts a mitral valve annulus; removing an adapter of the packaging system covering locations where the attachment sutures secure the valve holder to the prosthetic mitral valve, with the commissure constriction rod and attachment sutures remaining in place; tying down the implantation sutures; and removing the valve holder, commissure constriction rod, and attachment sutures, thereby implanting the prosthetic mitral valve.
