摘要:
A holder for a hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a non-expandable, non-compressible prosthetic valve and a self-expandable anchoring stent, thereby enabling attachment to the annulus without sutures. A first suture connects the holder to the valve and constricts an inflow end of the anchoring stent. A second suture connects the holder to the valve and extends down three holder legs to loop through fabric on the valve. Both sutures may loop over a single cutting well on the holder so that severing the first and second sutures at the single cutting well simultaneously releases the tension in the first suture, permitting the inflow end of the anchoring stent to expand, and disconnects the valve holder from the prosthetic heart valve.
