A prosthetic mitral valve assembly 100, i.e. support, comprises an annular body 102 configured to fit within the mitral annulus, first and second clips 104, 106 configured to attach the annular body 102 at a position corresponding to the meeting points of the natural posterior and anterior mitral leaflets, and rods 108 configured to attach said annular body to a patients left atrium, wherein said rods 108 are attached to and extend away from said annular body 102. It is further taught that the annular body 102, clips 104, 106 and rods 108 of the valve assembly 100 may be sized, shaped and/or arranged according to patient specific measurements. In particular, the annular body 102 may be sized to fit a patient specific size of a mitral annulus, the first and second clips 104, 106 may be located and attached to the annular body 102 according to patient specific positions of the meeting points of the posterior and anterior mitral leaflets, and the rods 108 may comprise a patient specific size, shape and orientation. A method of anchoring a prosthetic mitral valve assembly of this sort in a patients heart is also taught.
