Disclosed are annuloplasty rings having defined relationships between the intercommisural width and ratio of septo-lateral width to intercommisural width. The saddle- shaped annuloplasty rings may have a ratio of SLW to ICW of x ± (0.07 x x) when the ring has an intercommisural width of y, as determined according to the formula x = (y - 124) / -100.
