Abstract
A hinged heart valve holder and suturing method whereby the heart valve holder can be secured within a mechanical heart using a single suture. This suture operates both to secure the hinged heart valve holder within the annulus of the heart valve and to prevent the sewing ring from rotating on the annular valve body. Severing the suture at a single point both releases the heart valve holder and the sewing ring, permitting the annular valve body to be rotated within the sewing ring. Simultaneously, the suture remains secured to the heart valve holder and thus will be withdrawn in its entirety from the operation site.
