Abstract: An integrated heart valve rotator and holder comprising a central rotator which is used, first, to protect and stabilize the leaflets of the heart valve during implantation and, second, to rotate the heart valve into a desired position after the sewing ring has been attached. A heart valve holder mounts on the rotator and is secured to the heart valve suture ring by a thread or suture. After the heart valve is stitched into the proper location in the heart, the attending physician cuts the suture at a single location and withdraws the heart valve holder, rotator and suture as a single component. The heart valve holder, carrying both parts of the severed suture, is removed from the rotator. The rotator can then be returned to the heart valve to adjust the orientation of the annular valve body within the suture ring.
