The
mitral valve (also known as the
bicuspid valve or
left atrioventricular valve) is a dual-flap (
bi- from the Latin, meaning
double, and
mitral- from the Latin, meaning
shaped like a mitre)
valve in the
heart that lies between the
left atrium (LA) and the
left ventricle (LV). The mitral valve (not to be confused with the congenital
bicuspid aortic valve) and the
tricuspid valve are known collectively as the atrioventricular valves because they lie between the atria and the ventricles of the heart and control the flow of blood.
