Abstract

Apparatus (20, 220) is provided, including an artificial-chordeae-tendineae-adjustment mechanism (40) and at least one primary artificial chordea tendinea (60) coupled at a distal portion thereof (67) to the artificial-chordeae-tendineae-adjustment mechanism (40). A degree of tension of the at least one primary artificial chordea tendinea (60) is adjustable by the artificial-chordeae-tendineae-adjustment mechanism (40). One or more loops (66) are coupled at a proximal portion (65) of the at least one primary artificial chordea tendinea (60). The one or more loops (66) are configured to facilitate suturing of the one or more loops (66) to respective portions of a leaflet of an atrioventricular valve of a patient. Other applications are also described.
