TECHNIQUES FOR FACILITATING HEART VALVE TETHERING AND CHORD REPLACEMENT

A method is described, for use with a native valve (10) of a heart (4) of a subject, the valve being disposed between an atrium (6) and a ventricle (8) of the heart. A first radiopaque marker (32) and a second radiopaque marker (34) are percutaneously advanced to the heart. The first radiopaque mark...

Summary:A method is described, for use with a native valve (10) of a heart (4) of a subject, the valve being disposed between an atrium (6) and a ventricle (8) of the heart. A first radiopaque marker (32) and a second radiopaque marker (34) are percutaneously advanced to the heart. The first radiopaque marker is placed against a tissue site (42) in the ventricle. The second radiopaque marker is placed against a leaflet (12) of the valve. A distance is measured between the first radiopaque marker at the tissue site, and the second radiopaque marker at the leaflet. Responsively to the measured distance, a chord-length is determined. An artificial chord (60), selected based on the chord-length, is implanted in the heart. Other embodiments are also described.
