1. A method of treating a diseased aortic valve, comprising:

  • compressing a valve prosthesis to a compressed state, percutaneously delivering the valve prosthesis via a catheter through a femoral artery, and expanding the valve prosthesis to an expanded state in the diseased aortic valve,wherein the valve prosthesis comprises;

    a support stent comprising a tubular base and a plurality of axially-extending commissure posts coupled to the tubular base, the commissure posts having slots formed therein, the tubular base being self-expandable and comprising a shape memory material;

    a leaflet section comprising a plurality of leaflets made from pericardium, the leaflet section having an inlet end extending along a circumference of the tubular base and a plurality of commissures coupled to the commissure posts, wherein portions of the commissures extend outwardly through the slots in the commissure posts for securing the leaflet section to the commissure posts; and

    a skirt surrounding the tubular base, the skirt made from a biocompatible material and adapted for placement between the tubular base and surrounding tissue of the diseased aortic valve.
