1. A valve holder for holding and implanting a prosthetic heart valve, comprising a frame and three flexible valve leaflets that control directional flow of blood through a heart, a stent structure having three flexible commissure posts supporting the valve leaflets, each of the commissure posts having a tip, the valve holder comprising:
a valve holder body having an upper surface, a bottom surface shaped to abut an inflow side of the prosthetic heart valve, and a central axis;
a rotor insertable through the upper surface and positioned in the valve holder body, wherein when the prosthetic heart valve is coupled to the valve holder body, the rotor is rotatable around the central axis to adjust the prosthetic heart valve to a delivery position;
deployment sutures connecting the valve holder to the prosthetic heart valve, each deployment suture being attached to the rotor, routed through one of the commissure post tips and back to be tied off on the valve holder such that rotation of the rotor creates tension in each deployment suture to deflect each commissure post radially inward and adjust the prosthetic heart valve to the delivery position, the deployment sutures all passing over a single cutting guide on the upper surface of the valve holder body;
a guide mounted to the valve holder body and having a central opening;
an activator having a central shaft sized to pass through the central opening of the guide to engage and rotate the rotor around the central axis of the valve holder body; and
a latch configured to abut the guide, the latch being coupled to the valve holder body and having a guard that covers the cutting guide, such that the latch must be removed prior to severing the deployment sutures and converting the prosthetic heart valve from the delivery position to an implant position.
