Heart Valve Problems: Mitral Insufficiency

Mitral insufficiency means your mitral valve has problems closing. This lets blood leak back through the valve. A small amount of leaking blood rarely leads to problems. But severe cases can cause damage to the heart as the leaking of blood causes the blood to have to be pumped twice.
