Whats mitral regurgitation?

MR. The mitral valve has 2 leaflets which separates the left ventricle from the left atrium. Blood passes across the mv from the la to the lv when the heart is filling. When the ventricle contracts, the mv is closed and no blood goes backward into the la unless regurgitation is present. Then the blood leaks backward, overfilling the la and raising the pressure.
Mitral valve. The mitral valve has to open properly to let blood flow into the left ventricle from the atrium. If it doesn't, we call this stenosis. It has to close to keep the blood flowing toward the body, if it doesn't we call this regurgitation or insufficiency. Either or both problems can exist with the valve if its abnormal. Insufficiency is more common.
