1. An implantable heart valve device comprising:
a frame having a proximal end and a distal end and comprising at least a first pair of adjacent struts, the frame including an anti-backout feature configured to resist movement of the frame within a valve annulus;
a plurality of distally facing anchors carried by and extending distally away from the distal end of the frame in a distal direction and having distally extending ends configured to at least partially embed into tissue surrounding a native valve; and
a moveable restraint coupled with the frame and configured to restrain the frame at a desired configuration.
