Valve replacement can be used to treat any life-threatening valve disorder. In valve replacement surgery, the damaged valve is removed and replaced with either a mechanical or tissue valve. Mechanical valves are more durable than tissue valves and require lifelong anticoagulation. Tissue valves are generally less durable, requiring replacement sooner than mechanical valves.
Repairing a cardiac valve preserves the native valve. Not all valves can be repaired, as it’s dependent on the cause of the disorder and the amount of deterioration.
