Heart Valve Repair
Annuloplasty, which is one of the most common repair techniques, is aimed at repairing the fibrous tissue at the base of the mitral 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 annulus to make the opening smaller.
Sometimes when repairing the annulus, it is necessary for the surgeon to implant an annuloplasty ring. A ring is used to correct a structural problem, provide support for the valve, and reinforce the repair.
