If a faulty heart valve causes your heart failure, your doctor may recommend repairing or replacing the valve. The surgeon can modify the original valve (valvuloplasty) to eliminate backward blood flow. Surgeons can also repair the valve by reconnecting valve leaflets or by removing excess valve tissue so that the leaflets can close tightly.
