Mitral regurgitation is the most common type of heart valve disorder. Blood that flows between different chambers of your heart must flow through a valve. The valve between the two chambers on the left side of your heart is called the mitral valve.
The mitral valve is also prone to a disease referred to as mitral valve prolapse. With mitral valve prolapse, the mitral valve bulges slightly back into the left atrium when it closes, allowing a small amount of blood to leak backward. Mitral Valve Insufficiency/Regurgitation.1  Overview: Mitral valve insufficiency/regurgitation is a disease in which the mitral valve does not close completely, causing blood to flow backward instead of forward through the valve. 2  Mitral valve insufficiency/regurgitation may develop in response to a number of conditions.itral Valve Regurgitation, Stenosis, and Prolapse. The mitral valve is referred to as atrioventricular valves because it is located between the left atria and the left ventricle.
