Definition: Mitral regurgitation is the pushing of some blood backward to the left atrium when the left ventricle pumps instead of to the aorta. In this case there is either mitral insufficiency or prolapse. This may or may not lead to CHF depending on the amount. CHF is when the pressure backward to the lungs is great and fluid seeps out of to the lung tissues causing edema in the lungs.
