What are the causes and symptoms of mitral valve stenosis?
Mitral valve stenosis is almost always caused by rheumatic fever. As a result of rheumatic fever, the leaflets that form the opening of the valve are partially fused together. Mitral valve stenosis can also be present at birth. Babies born with this problem usually require surgery if they are to survive. Sometimes, growths or tumors can block the mitral valve, mimicking mitral valve stenosis. If the restriction is severe, the increased blood pressure can lead to heart failure. The first symptoms of heart failure, which are fatigue and shortness of breath, usually appear only during physical activity. As the condition gets worse, symptoms may also be felt even during rest. A person may also develop a deep red coloring in the cheeks. Source: The Gale Group.
