📋Overview
Mitral valve regurgitation (MR) is a heart valve disorder characterized by the backward flow of blood from the left ventricle into the left atrium during systole due to improper closure of the mitral valve. It is a common valvular heart disease and can range from mild to severe. The term 'mitral valve insufficiency' is sometimes used synonymously. This condition is distinct from mitral stenosis, which involves valve narrowing rather than leakage.
