A mitral valve annuloplasty ring having: an anterior portion including A1, A2, and A3 segments; a posterior portion including P1, P2, and P3 segments, the segments being connected in a closed loop series in the order A1, A2, A3, P3, P2, and P1, such that the A1 and P1 segments meet and the A3 and P3 segments meet, the ring being adapted for attachment to the annulus of a patient's mitral valve adjacent respective A1, A2, A3, P3, P2, and P1 leaflet portions of the mitral valve, such that the A1 and P1 segments of the ring meet adjacent to a first commissure of the mitral valve and the A3 and P3 segments meet adjacent to a second commissure of the mitral valve; an AP axis that extends from the anterior portion to the posterior portion; a first reference point located on the anterior portion to one side of the AP axis; a second reference point located on the anterior portion to the other side of the AP axis; a third reference point located on the posterior portion to one side of the AP axis, the AP axis being perpendicular to a line between the first and second reference points (R1, R2), and the first and second reference points (R1, R2) and the AP axis being located so that the AP axis bisects a greatest width dimension of the ring that is measured perpendicular to the AP axis, each of the first through third reference points (R1, R2, R3) being spaced from the AP axis by 0.5 mm, and the first through third reference points (R1, R2, R3) lying in and thereby defining a plane; a fourth reference point where the A1 and P1 segments meet; and a fifth reference point where the A3 and P3 segments meet, the fourth and fifth reference points (A1/P1, A3/P3) being spaced below the reference plane when the reference plane is a plan view plane of the ring in which the A2 segment is at the top of the plan view, the P2 segment is at the bottom of the plan view, the A1 segment is toward the left in the plan view, and the A3 segment is toward the right in the plan view, and spacing of the fifth reference point (A3/P3) below the reference plane being greater than spacing of the forth reference point (A1/P1) below the reference plane, such that the ring is configured to provide greater downward depression of the annulus at the second commissure of the mitral valve where the A3 and P3 segments meet than at the first commissure of the mitral valve where the A1 and P1 segments meet. an anterior portion including A1, A2, and A3 segments; a posterior portion including P1, P2, and P3 segments, the segments being connected in a closed loop series in the order A1, A2, A3, P3, P2, and P1, such that the A1 and P1 segments meet and the A3 and P3 segments meet, the ring being adapted for attachment to the annulus of a patient's mitral valve adjacent respective A1, A2, A3, P3, P2, and P1 leaflet portions of the mitral valve, such that the A1 and P1 segments of the ring meet adjacent to a first commissure of the mitral valve and the A3 and P3 segments meet adjacent to a second commissure of the mitral valve; an AP axis that extends from the anterior portion to the posterior portion; a first reference point located on the anterior portion to one side of the AP axis; a second reference point located on the anterior portion to the other side of the AP axis; a third reference point located on the posterior portion to one side of the AP axis, the AP axis being perpendicular to a line between the first and second reference points (R1, R2), and the first and second reference points (R1, R2) and the AP axis being located so that the AP axis bisects a greatest width dimension of the ring that is measured perpendicular to the AP axis, each of the first through third reference points (R1, R2, R3) being spaced from the AP axis by 0.5 mm, and the first through third reference points (R1, R2, R3) lying in and thereby defining a plane; a fourth reference point where the A1 and P1 segments meet; and a fifth reference point where the A3 and P3 segments meet, the fourth and fifth reference points (A1/P1, A3/P3) being spaced below the reference plane when the reference plane is a plan view plane of the ring in which the A2 segment is at the top of the plan view, the P2 segment is at the bottom of the plan view, the A1 segment is toward the left in the plan view, and the A3 segment is toward the right in the plan view, and spacing of the fifth reference point (A3/P3) below the reference plane being greater than spacing of the forth reference point (A1/P1) below the reference plane, such that the ring is configured to provide greater downward depression of the annulus at the second commissure of the mitral valve where the A3 and P3 segments meet than at the first commissure of the mitral valve where the A1 and P1 segments meet.
