An annuloplasty is done to reshape, reinforce, or tighten the ring around a damaged or diseased heart valve.
The ring around a valve in the heart is called the annulus. It can widen and change from its usual shape. The shape change may prevent the valve's flaps from opening and closing correctly. So blood can leak backward through the valve, a condition called valve regurgitation. A heart that is larger than usual or a leaky heart valve may cause the annulus to change shape.
An annuloplasty may be done to fix the valve. Other surgeries to repair a heart valve may be done at the same time.
