Mitral regurgitation (MR) is a condition in which the heart's mitral valve leaflets do not coapt (close) tightly. This allows some blood to flow backward into the left atrium (upper heart chamber), rather than through the aorta to the rest of the body. If the regurgitation is significant, the patient may feel tired or out of breath due to decreased efficiency of the heart. Treatment of MR depends on its severity.
It also depends on whether the patient experiences symptoms or the condition is worsening.
For mild leakage, treatment is usually not necessary. Severe leakage or regurgitation may call for surgical intervention to repair or replace the dysfunctional valve. Left untreated, it can cause heart failure or arrhythmias. Even patients without symptoms may require evaluation by a cardiologist and trained surgeon to determine whether early intervention may be beneficial.
Symptoms of mitral valve disease may not be experience for many years. Signs and symptoms of MR, which depend on its severity and progression, can include:
MR is often mild and progresses slowly. However, the problem may develops quickly, and a sudden onset of severe signs and symptoms can occur.
Primary MR is caused by problems with the valve, itself. Diseases of the left ventricle can lead to secondary or functional MV regurgitation.
Possible causes of MR include:
Several factors can increase a patient's of mitral valve regurgitation, such as:
