Annuloplasty rings that are size-adjustable after implant and which facilitate deployment and reduce long-term complications. The rings each have a hollow support body with a cinching element extending therethrough whose length is controlled remotely via a deployment system handle. The ring may be anchored to the annulus and then the size adjusted while the heart beats and under visualization to minimize regurgitation. The cinching element may be a loop of braided metal cable which cooperates with a junction housing to which the deployment system attaches. The rings are especially beneficial for repairing the mitral annulus, and may be saddle shaped with the junction housing located on an anterior side. The support body may be shape set nitinol tube having cutouts for flexibility, and the cinching element may be a braided nitinol core having a braided polymer exterior. The cinching element may be a complete loop, have one end anchored in the junction housing, or have two free ends extending out of the junction housing.
