A method is provided that includes implanting (a) a first venous tissue anchor in a superior vena cava, an inferior vena cava, or a coronary sinus, (b) exactly two atrial tissue anchors, which consist of second and third atrial tissue anchors, at respective different atrial sites, each of which sites is selected from: an annulus of a tricuspid valve, and a wall of a right atrium of a heart above the annulus, and (c) a pulley system, which includes (i) a pulley, which is connected to the second atrial tissue anchor, and (ii) a tether, which (A) is connected to the first venous tissue anchor and the third atrial tissue anchor, (B) is moveable through the pulley, and (C) has a length, measured between the first venous and the third atrial tissue anchors, of at least 30 mm. A size of a tricuspid orifice is reduced by tensioning the tether.
