1. A method of implanting a surgical prosthetic heart valve at a heart valve annulus, wherein the valve comprises a resilient frame including alternating cusp and commissure portions and having a neutral configuration defining a circular prism leaflet support structure, the valve further including a sewing ring around an inflow end of the resilient frame, the valve further including flexible leaflets supported by the leaflet support structure, the method comprising:

  • retaining the surgical prosthetic heart valve in a collapsed delivery configuration in which the resilient frame defines a non-circular prism, wherein the commissure portions of the resilient frame are folded inwardly toward a longitudinally collapsed position when the valve is positioned in the collapsed delivery configuration;

    making an outer incision leading to a body lumen;

    making an inner incision in the body lumen to provide direct access to a heart valve annulus;

    inserting the valve in the collapsed delivery configuration through the outer and inner incisions and into the body lumen;

    advancing the valve to the heart valve annulus;

    securing the sewing ring to the heart valve annulus; and

    releasing the valve from the collapsed delivery configuration such that the valve independently recovers to the neutral configuration.
