1. A beating heart method of securing a prosthetic valve at a native valve between an atrium and a ventricle, the native valve having native leaflets and attached chords in the ventricle, and commissures between the leaflets at a native annulus of the native valve, comprising:
advancing an anchor device to the native valve, the device having a ventricular portion and an atrial portion, the ventricular portion having an expandable tubular body about a vertical axis comprising undulating struts, the tubular body having two leaflet clamping portions opposite one another each defined by at least one peak and two valleys, the device further including two upstanding vertical posts each commencing at a separate valley of the undulating struts and extending upward beyond a maximum height of the peaks of the two leaflet clamping portions and terminating in the atrial portion;
expanding the ventricular portion of the device in the ventricle and positioning the two leaflet clamping portions radially outside respective leaflets of the native leaflets;
positioning the upstanding posts such that they project upward at the valve commissures and support the atrial portion above the native annulus in the atrium; and
advancing an expandable prosthetic valve to within the native leaflets and expanding to compress the native leaflets outward against the two leaflet clamping portions of the device.
