The mitral valve is also known as the left atrioventricular valve. It prevents blood flow back into the atria while the ventricles are contracting. There are also two types of circulation through the heart. The systemic circuit carries blood to and from all the body tissues and is operated by the left side of the heart. The pulmonary circuit carries blood to and from the lungs and is operated by the right side of the heart. Because this valve is located on the left side, the systemic circulation is affected when the mitral valv is not functioning correctly.
