In certain aspects, the invention relates to a method ter generating a mitral repair ring for a corresponding mitral valve, comprising the steps of generating (S1) a reference circumference (13) indicative of said valve ring (130); generating (S2) a reference grid (2); inscribing (S3) said reference circumference (13) in said reference grid (2); combining (S4) said reference circumference (33) with a plurality of characteristic measures (15, 16,17, r1-r6) of said mitral valve (100); generating (S5) a three-dimensional reference grid (250); identifying (S6) on said three-dimensional reference grid (250) a plurality of deformation points (300-302) of said reference circumference (13); deforming said reference circumference (13) at said deformation points (300-303) so as to obtain a geometric model (10) of said mitral repair ring (10′); and generating said mitral repair ring (10′) from said obtained geometric model (10). The invention also relates to the mitral repair ring obtained by means of the aforesaid method and to its use in mitral annuloplasty.
