Methods and apparatus are provided for valve repair or replacement. In one embodiment, the method comprises providing an apparatus having a valve prosthesis, a valve leaflet support and a valve excisor, the apparatus having a first configuration and a second configuration; accessing the aortic root without placing the patient on a heart-lung machine; advancing the apparatus in the first configuration where the valve leaflet support is advanced through a valve, wherein the support is positioned below a valve annulus; expanding the apparatus into a second configuration so that the support will engage the valve; and moving the valve leaflet support and valve excisor together to remove leaflets of the valve. Penetrating members may be advanced into the tissue wherein the penetrating members may act as fasteners to hold the prosthesis in place. |
