1. A method of implanting an expandable prosthetic valve within a native mitral valve between an atrium and a ventricle, the method comprising:
releasing terminal ends of ventricular anchors of the prosthetic valve from a constrained delivery position of the ventricular anchors by distally advancing a distal capsule portion relative to a remaining portion of a delivery capsule which houses the prosthetic valve in a constrained delivery position, such that by the releasing, the terminal ends of the ventricular anchors move outwardly, while the ventricular anchors are positioned within the atrium;
after releasing the terminal ends of the ventricular anchors positioned within the atrium, advancing at least a portion of the expandable prosthetic valve containing the ventricular anchors through the native mitral valve into the ventricle;
releasing terminal ends of atrial anchors of the prosthetic valve relative to a portion of an annular valve body of the prosthetic valve by proximally retracting a proximal capsule portion relative to the delivery capsule, such that by the releasing, the terminal ends of the atrial anchors move outwardly, while the atrial anchors are at least partially positioned within the atrium; and
after releasing the terminal ends of the ventricular anchors and releasing the terminal ends of the atrial anchors, further distally advancing the distal capsule portion such that the annular valve body expands radially 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.
