ABSTRACT:
An implantable prosthetic heart valve with a suturing ring having an interiorly disposed split ring of constant diameter for securing the suturing ring fabric to the heart valve body and providing a constant rotational torque for facilitating rotation of the heart valve body with respect to the suturing ring. The split ring is formed of a stiff band having opposed split ring ends that are drawn together and held in place by fixation cords. The split ring may include flanges extending in the inflow and/or outflow directions to inhibit passage of suture needles through inflow and/or outflow rim bands of the suturing ring fabric to encourage proper surgical installation. The flanges may be extended in the inflow and/or outflow directions sufficiently to increase blood flow velocity past the inflow and/or outflow rim bands and discourage pannus growth over the interface of the respective rim bands and valve body flanges and into the valve body annulus and to provide added safety by forming a barrier against impingement of the occluder by suture tails and heart tissue.
