Structures of the Heart
It is called the 'bicuspid valve' because it is formed from two (bi-) cusps. As it is also known as the 'mitral valve', it is useful to recognize both of these expressions.
The mitral valve in the heart consists of two flaps known as 'cusps' attached to the walls between the left atrium (LA) and the left ventricle (LV). This valve enables blood to pass from the left atrium of the heart to the left ventricle of the heart - while also preventing flow of blood in the opposite direction (from the left ventrile to the left atrium).
The cusps of the mitral valve work in the same way as the cusps of the tricuspid valve. That is, in order for blood to pass from an atrium to a ventricle, an atrioventricular valve must open. The opening and closing of these valves are controlled by the difference in pressure across the atrioventricular valves.
