1. A method for replacing a cardiac valve having at least two native valve leaflets, said method comprising the steps of:

  • providing a prosthetic valve that includes an expandable support member having oppositely disposed first and second ends and a main body portion extending between the ends, a plurality of upper wing members that extend from a one end of the main body portion, and a plurality of lower wing members that extend from an opposite end of the main body portion, the second end of the support member further including at least two strut members, the prosthetic valve having at least two valve leaflets joined at two or more commissural sections, each of the commissural sections being attached to a strut member to prevent prolapse of the valve leaflets;

    placing the main body portion of the prosthetic valve within the annulus of the cardiac valve to be replaced;

    expanding the main body portion into engagement with the annulus of the cardiac valve to secure the prosthetic valve in the annulus;

    deploying the upper wing members from a radially collapsed condition into a radially extended condition to engagement with a first section of cardiac tissue surrounding one side of the cardiac valve; and

    deploying the lower wing members from a radially collapsed condition into a radially extended condition to engage a portion of the native valve leaflets to pin the leaflets back against the annulus of the native cardiac valve.
