Abstract

During a percutaneous procedure, a flexible sleeve of an annuloplasty structure is introduced into an atrium and arranged completely around an annulus as a closed loop, such that none of one or more longitudinal contracting members thereof is positioned along an anterior portion of the annulus between fibrous trigones of the valve. The annuloplasty structure is fastened to the annulus. At least a portion of a posterior portion of the annulus is tightened, while preserving a length of an anterior portion of the annulus between fibrous trigones of the valve, by contracting, using the one or more longitudinal contracting members, a longitudinal portion of the sleeve not positioned along the anterior portion of the annulus between the fibrous trigones of the valve. Thereafter, the one or more longitudinal contracting members are locked.
