ANATOMY

Detailed explanation-1: -The valve that is present between the left atrium and left ventricle of the heart is called the bicuspid or mitral valve. It consists of two cusps or flaps that prevent the backflow of oxygenated blood from the left ventricle to the left atrium.

Detailed explanation-2: -It is present between the left atria and left ventricle. During ventricular contraction, the bicuspid valve prevents backward movement of the blood, i.e. from the left ventricle into the left atrium.

Detailed explanation-3: -A bicuspid aortic valve (BAV) is an aortic valve that contains only only two cusps (or flaps) instead of three. The aortic valve controls the flow of blood from the left ventricle (chamber) to the aorta, the main artery delivering blood to your body.

Detailed explanation-4: -When this happens, the condition is called aortic valve stenosis. The heart has to work harder to pump blood into the body’s main artery, called the aorta. Bicuspid aortic valve is a heart problem present at birth. That means it is a congenital heart defect.

Detailed explanation-5: -Since the right side of the heart must move the same amount of blood as the left side but at much lower pressure, it is necessary that the valve open much more readily to allow the same volume to pass through (the three parts of the valve would allow it to open more circular).
