Degenerative Disease

Mitral valve regurgitation is present when the valve does not close completely, causing blood to leak back into the left atrium. Mitral valve stenosis is present when the valve does not open completely, causing a relative obstruction to blood flow. Both of these conditions increase the workload on the heart and are very serious conditions. If left untreated, they can lead to debilitating symptoms including arrhythmia, congestive heart failure, and irreversible heart damage.
