Abstract
A method is provided including making an opening (300) through an atrial septum (302) at a septal site (304) at least 5 mm from a fossa ovalis (330). A first tissue anchor (204) is endovascularly advanced to a left-atrial site (306) on an annulus of a mitral valve (310) or a wall of a left atrium (308) above the annulus. The first tissue anchor (204) is implanted at the left-atrial site (306). A second tissue anchor (24) is endovascularly advanced to a right-atrial site (320) on an annulus of a tricuspid valve (207) or a wall of a right atrium (200) above the annulus. The second tissue (24) anchor is implanted at the right-atrial site (320). The left-atrial site (306) and the right-atrial site (320) are approximated by tensioning a tether (22) that passes through the opening (300) of the atrial septum (302) and connects the first and the second tissue anchors (204, 24). Other embodiments are also described.
