Valve Disease -Valvular Heart Disease

Heart valves direct the blood flow within the four chambers of the heart. If the valves malfunction, symptoms may occur. The most common problems caused by valve disease are narrowing or leaking of a valve.

Narrowing of a Valve Leaky Valve
Valvular stenosis occurs when the valve does not open properly. This narrowing from scar tissue or calcium deposits, causes the heart to work harder, which over time can cause the heart to weaken and fail. When a valve does not close properly, it causes blood to leak backwards. This may cause the heart to work harder and can result in a weakened or failing heart.
