Mitral Valve Disease (Regurgitation)
The mitral valve is located between the left atrium and the left ventricle and controls the flow of blood as it returns from the lungs before being pumped out to the body. It is a one-way valve that opens and closes with each heartbeat. When open, the valve allows blood to pass from the atrium into the ventricle. When closed, it prevents blood from returning to the atrium.
A healthy mitral valve maintains blood flow in one direction, from the atrium to the ventricle, and from the ventricle to the rest of the body. If the valve becomes damaged, surgery may be necessary to ensure proper blood flow through the heart.
Mitral valve disease is often asymptomatic in its early stages. Over time, patients will notice common symptoms such as shortness of breath, lightheadedness, fatigue, racing or irregular heartbeat (arrhythmia), and a dry cough.
The Following Conditions Sometimes Cause Mitral Valve Disease:
- Acquired Valve Disease*: Problems involving the structure of a valve that develop over time, including rheumatic fever, endocarditis and more
- Mitral Stenosis: Narrowing of mitral valve opening that restricts blood flow from the left atrium to the left ventricle
- Mitral Regurgitation: Mitral valve leak that causes blood to flow backward through the heart and into the lungs
- Structural Problems: Congenital valve disease that develops before birth
