Mitral stenosis means the mitral valve is abnormally narrow which can prevent the blood from flowing smoothly or quickly through it.Īngina pectoris means “pain in the chest” and occurs if the heart is not receiving enough blood. Mitral valve regurgitation happens when the mitral valve does not close all the way and causes a leak, allowing some of the oxygenated blood to flow backward. The mitral valve pumps freshly oxygenated blood out of the heart to the rest of the body. Mitral valve prolapse means the mitral valve bulges out or prolapses because it does not close evenly.
