About Mitral RegurgitationMitral regurgitation (MR) is the most common type of heart valve insufficiency, 1 affecting approximately one in 10 people aged 75 years and older. The condition occurs when the leaflets of the mitral valve do not close completely, causing blood to flow backward and leak into the left atrium of the heart during the cardiac cycle. To maintain an adequate forward flow of blood throughout the body, the heart compensates by increasing the size of the left ventricle, the main pumping chamber of the heart. This requires the heart to work harder, and may ultimately lead to irregular heartbeats, stroke, heart attack or death. MR may also lead to heart failure, a potentially deadly condition that occurs when the heart is unable to pump sufficiently to distribute blood flow to meet the needs of the body.
