ABSTRACT:
Suturing rings and methods of use thereof facilitating initial implantation of new and replacement of dysfunctional tissue or mechanical heart valve mechanisms supported by the suturing ring are disclosed. The suturing ring annulus is adjustable to receive and engage the valve frame of the heart valve mechanism within the annulus. An interlocking mechanism applies restraint to fix the adjusted suturing ring annulus engaged against the valve frame to support the heart valve mechanism during chronic implantation. Sutures affixing the suturing ring to the valvar rim can be routed and entrapped between the suturing ring annulus and the valve frame when the suturing ring is restraint is applied. The restraint is released to replace a dysfunctional heart valve mechanism and reapplied when a new heart valve mechanism is fitted into the annulus.
