Abstract
Methods of remodeling an abnormal mitral valve with an annuloplasty ring having a reduced anterior-to-posterior dimension to restore coaptation between the mitral leaflets in mitral valve insufficiency (IMVI). The ring has a generally oval shaped body with a major axis perpendicular to a minor axis. An anterior section lies between anteriolateral and posteriomedial trigones, while a posterior section defines the remaining ring body and is divided into P1, P2, and P3 segments. The anterior-to-posterior dimension of the ring body is reduced from conventional rings; such as by providing, in atrial plan view, a pulled-in P3 segment. The ring body may have a downwardly deflected portion in the posterior section. The downwardly deflected portion may have an apex which is the lowest elevation of the ring body and may be offset with respect to the center of the downwardly deflected portion toward the P3 segment.
