1. A method of treating aortic insufficiency, comprising:

  • delivering a support structure to a position on or adjacent to the surface of the outflow side of a native heart valve of a patient, the support structure comprising an annular body defining an interior and at least one projection extending radially inwardly from the annular body;

    positioning the support structure around the leaflets of the native heart valve such that the leaflets of the native heart valve are located within the interior of the annular body;

    advancing an expandable prosthetic heart valve into the native heart valve and into the interior of the annular body, the prosthetic heart valve comprising a radially expandable annular frame defining a plurality of openings; and

    expanding the expandable prosthetic heart valve into contact with the leaflets of the native valve, thereby causing the leaflets of the native valve to be frictionally secured between an inner surface of the annular body and an outer surface of the prosthetic heart valve and causing the at least one projection and a portion of one of the leaflets contacted by the at least one projection to extend into one of said openings of the frame.
