A method is provided for repairing the tricuspid valve of a patient using tension. A radially-expandable stent is implanted in a coronary sinus of the patient. A tissue anchor is implanted in tissue in the vicinity of the tricuspid valve. The tricuspid valve is repaired by applying tension between the radially-expandable stent and the tissue anchor using a flexible longitudinal member that connects the radially-expandable stent and the tissue anchor.
