1. A prosthetic heart valve system, comprising:
a prosthetic heart valve including a self-expanding frame, the self-expanding frame having an atrial end forming a cuff with a collar shape, and a tubular portion, the prosthetic heart valve further including a leaflet assembly positioned within the self-expanding frame;
a tether secured to the self-expanding frame at a ventricular end thereof, and
an anchor device having a base member and a hub, the hub having an outer perimeter received within a retaining channel of the base member so that the hub can rotate relative to the base member, the hub and the base member collectively defining a tether passageway being sized and shaped to receive the tether therethrough, the base member defining a locking pin channel that intersects with the tether passageway, the anchor device further including a locking pin assembly having a piercing portion received within the locking pin channel;
wherein when the tether is received through the tether passageway, the hub is rotatable relative to the base member between an unpinned condition and a pinned condition, the piercing portion of the locking pin assembly being disposed outside of the tether passageway and not piercing the tether in the unpinned condition, the piercing portion of the locking pin assembly extending through the tether passageway and piercing the tether in the pinned condition,
wherein when the piercing portion of the locking pin assembly is disposed outside of the tether passageway in the unpinned condition, no portion of the locking pin assembly extends through the tether passageway,
wherein rotating the hub relative to the base member between the unpinned condition and the pinned condition drives the locking pin through the tether passageway; and
wherein the locking pin assembly includes a driver portion, the driver portion being received within a curved cam channel of the hub.
