Annuloplasty is a technique aimed at repairing the fibrous tissue at the base of the heart valve (the annulus). Sometimes, the annulus becomes enlarged, which enables blood to back up into the atrium. To repair this, sutures are sewn around the ring to make the opening smaller. This creates a purse string effect around the base of the valve and helps the leaflets meet again when the valve closes.
