I have MVLeakage. I am getting more fatigued and sob. Especially after the least exertion and bending over? This is complicated because I also am being treated for Mycobacteria in my lungs. What are the most specific signs of worsening Mitral valve leakag

Hello Anonymous,

Welcome to EmpowHER. I am sorry to hear about this. Do keep in close contact with your physician and report any concerns.

Mitral regurgitation is leakage of blood backward through the mitral valve each time the left ventricle contracts.

A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve — as it should — and some blood flows back into the atrium.

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 (pulmonary veins).

If regurgitation is severe, increased pressure may result in congestion (or fluid build-up) in the lungs.

When regurgitation is more severe, a person may have palpitations, especially when lying on the left side.

If regurgitation is severe enough, the heart may enlarge to maintain forward flow of blood, causing heart failure (when the heart does not pump enough blood to the body). This may produce symptoms ranging from shortness of breath during exertion, coughing, congestion around the heart and lungs, swelling of the legs and feet.
