Dr. Bennett Werner answered

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.
