What is a heart valve replacement?
Reasons for doing this procedure are: One or more of the valves in your heart may not open or close all the way. The valve may not be working well because it is scarred by disease or because it was abnormal at birth. It is used only when: Medicines are not effective. Opening (balloon valvotomy) or repairing abnormal valves (surgical valvuloplasty) will not work.
