1. A method of performing annuloplasty of a mitral valve having valve leaflets and a condition resulting in diminished valve leaflet coaptation comprising:

  • determining a transverse dimension and an anterior-posterior dimension of the mitral valve annulus;

    selecting for implantation to the mitral valve annulus a mitral valve annuloplasty ring having a ring body covered by a suture-permeable sewing cuff, the ring body defining an orifice having a major axis perpendicular to a minor axis, the major and minor axes being generally perpendicular to a flow axis, whereina) a major axis dimension of the ring body is less than the annulus transverse dimension, andb) a ratio of a minor axis dimension of the ring body to the major axis dimension is less than the ratio of the anterior-posterior dimension to the transverse dimension of the mitral valve annulus; and

    implanting the ring so as to constrict the native annulus and restore healthy coaptation between the leaflets without reducing excessively the overall orifice area of the ring.
