An annuloplasty ring is secured around an annulus of a heart valve of a subject by securing an anterior-configured portion of the annuloplasty ring, a posterior-configured portion of the annuloplasty ring, a first commissural portion of the annuloplasty ring, and a second commissural portion of the

An annuloplasty ring is secured around an annulus of a heart valve of a subject by securing an anterior-configured portion of the annuloplasty ring, a posterior-configured portion of the annuloplasty ring, a first commissural portion of the annuloplasty ring, and a second commissural portion of the annuloplasty ring, to respective portion of the annulus. Subsequently, and while the heart is beating, the first commissural portion of the annuloplasty ring is moved inferiorly downwardly with respect to another portion of the annuloplasty ring by rotating a respective first adjusting mechanism of the annuloplasty ring structure, and the second commissural portion of the annuloplasty ring is moved inferiorly downwardly with respect to the other portion of the annuloplasty by rotating a respective second adjusting mechanism of the annuloplasty ring structure. Other embodiments are also described.
