Mitral Valve Disease refers to a condition affecting the mitral valve, which is located between the left atrium and left ventricle of the heart. This valve helps regulate blood flow, ensuring it moves in the correct direction. When the mitral valve does not function properly, it can lead to problems such as mitral regurgitation, where blood leaks backward, or mitral stenosis, where the valve becomes narrowed. Symptoms of mitral valve disease may include shortness of breath, fatigue, and irregular heartbeats. Diagnosis typically involves echocardiograms and other imaging tests to assess the valve's structure and function. Treatment options vary and may include medication or surgical interventions to repair or replace the valve.
