Mitral regurgitation is leakage of blood backward through the mitral valve each time the heart contracts. A leaking mitral valve allows blood to flow in two directions during the contraction. Leakage can increase blood volume and pressure in the area. The increased blood pressure in the left atrium can increase pressure in the veins leading from the lungs to the heart. If regurgitation is severe, increased pressure may result in congestion in the lungs. Enlargement of the heart can cause heart failure. Symptoms may range from shortness of breath during exertion, coughing, congestion in the lungs, swelling of the legs and feet.
Mild MR may not need treatment, but the more severe cases usually require surgery. For complications due to enlarged chamber of the heart, certain medications may need to be started (e.g blood thinners to reduce stroke risk in patients with atrial fibrillation)
