An apparatus for treating a mitral valve, comprising an elongate member having a spiral shape, the elongate member having a proximal end portion and a distal end portion, an expandable proximal anchor joined to the proximal end portion of the elongate body, and an expandable distal anchor joined to the distal end portion of the elongate body. The elongate member is configured to adjust from an elongated state to a shortened state after delivery at least partially into a coronary sinus for reshaping a mitral annulus.
