1. A method of securing a cardiac implant to a heart valve annulus, comprises:

  • providing a pre-assembled cardiac implant system including an implant defining a flow orifice through which blood will flow when implanted from an inflow side to an outflow side of the implant, the implant including a pliant sealing edge extending outward therefrom having a plurality of generally axial slits that open radially outward, the system further including a plurality of knotless suture fasteners attached to and distributed around the sealing edge, each fastener having an axial slot sized to receive a suture and facing radially outward so as to align with one of the axial slits;

    pre-installing a plurality of anchoring sutures at the annulus, each anchoring suture being passed through the annulus with at least one free end extending away from the annulus;

    passing each of the free ends of the anchoring sutures radially inward through one of the axial slits in the sealing edge and into the aligned suture fastener slot;

    advancing the cardiac implant distally until the sealing edge seats against the annulus; and

    deploying the suture fasteners to clamp onto the free ends of the anchoring sutures.
