The mitral valve is also called the bicuspid valve and the left atrioventricular valve. As the name bicuspid valve may suggest, the mitral valve is considered to have two primary leaflets: the anterior and posterior leaflets. The anterior leaflet has also been called the septal, medial, or aortic leaflet, while the posterior leaflet is also referred to as the lateral, marginal, or mural leaflet.
The antrioventricular valve has two valves. The bicuspid valve has 2 flaps and in located in the right ventricle/right atrium. The tricuspid valve has 3 flaps and is located in the left ventricle/left atrium.
