1. A method of releasing a valve from a delivery capsule in a heart, the method comprising:

  • advancing the delivery capsule into the heart, the delivery capsule comprising a distal capsule portion and a proximal capsule portion, wherein the distal capsule portion and the proximal capsule portion are held together to retain the valve between the distal capsule portion and proximal capsule portion during the advancement of the delivery capsule into the heart;

    moving the distal capsule portion a first distance in the heart in a first direction to release ventricular anchoring legs of the valve from the delivery capsule;

    moving the proximal capsule portion a second distance in a second direction in the heart, opposite the first direction, to release atrial anchoring arms of the valve from the delivery capsule; and

    after the release of the ventricular anchoring legs and the atrial anchoring arms from the delivery capsule, moving the distal capsule portion a third distance in the first direction in the heart to release an annular valve body of the valve from the delivery capsule.
