1. A system for adjusting tension in an artificial chordae tendineae, the system comprising:
an artificial chordae tendineae coupleable between a clip and an anchor;
the clip engageable with a leaflet of a heart valve; and
the anchor engageable with a papillary muscle or heart wall, the anchor including:
a body portion;
a locking portion engageable with the artificial chordae tendineae and configured to allow movement of the artificial chordae tendineae in a first direction while preventing movement of the artificial chordae tendineae in a second direction opposite the first direction; and
an actuator proximally movable to selectively release the locking portion to enable selective movement of the artificial chordae tendineae in the second direction.
