A method for delivering a heart valve prosthesis to a native valve annulus comprises expanding an expandable frame at the native valve annulus and positioning a replacement heart valve within the expandable frame. The expandable frame preferably includes a first anchoring portion that is positioned on a first side of the native valve annulus and a second anchoring portion that is positioned on a second side of the native valve annulus. The first anchoring portion engages tissue on the first side of the native valve annulus and the second anchoring portion engages tissue on the second side of the native valve annulus for securing the expandable frame to the native valve annulus. The replacement heart valve comprises a plurality of leaflets for replacing the function of the native valve.
