Mitral valve regurgitation


Mitral valve regurgitation is a condition in which the heart's mitral valve doesn't close tightly. This allows blood to flow backward in the heart.


Symptoms include shortness of breath, fatigue, lightheadedness, and a rapid, fluttering heartbeat.


Some people may not need treatment. More-severe cases may require medications, such as diuretics and blood thinners, or surgery.
