An expandable prosthetic valve is implantable within a native mitral valve by terminal ends of ventricular anchors of the prosthetic valve moving outwardly from a constrained delivery position of the ventricular anchors, while the ventricular anchors are positioned within the atrium. Then, a portion of the expandable prosthetic valve containing the ventricular anchors is advanced through the native mitral valve into the ventricle. Terminal ends of atrial anchors of the prosthetic valve move outwardly relative to a portion of an annular valve body of the prosthetic valve while the atrial anchors are at least partially positioned within the atrium. Next, the annular valve body is radially expanded while the ventricular anchors are in the ventricle and the atrial anchors are in the atrium, thereby anchoring native heart valve tissue between the atrial anchors and ventricular anchors. Other embodiments are also described.
