Abstract
Apparatus and methods are described for use with an annuloplasty ring (20), and an atrioventricular valve of a heart of a mammalian subject, the atrioventricular valve including a valve annulus, valve leaflets, chords, and papillary muscles. A plurality of chord-manipulation arms (26) are configured to be deployed among the chords of the atrioventricular valve, and to cause a size of the valve annulus to decrease, by the chord-manipulation arms (26) being rotated such as to twist the native atrioventricular valve and pull the native atrioventricular valve radially inwards, by the chord-manipulation arms (26) deflecting the chords. The chord-manipulation arms (26) are configured to subsequently provide a counterforce against which the annuloplasty ring (20) is pushed, during implantation of the annuloplasty ring (20). Other applications are also described.
