Tricuspid and bicuspid valves are closed while ventricles are in diastole.
The mitral valve, otherwise called the bicuspid valve or left atrioventricular valve, is one of the four heart valves. Tricuspid and bicuspid valves are the two sorts of AV valves of the heart. They are comprised of endocardium and connective tissue. Both are situated between the chamber and ventricle. Bicuspid and tricuspid valves are associated with forestalling the discharge of ventricular blood to the atria. Bicuspid valves comprise of two cusps while the tricuspid valves have three cusps. The restricting of the bicuspid and tricuspid valves because of specific deformities is known as mitral stenosis and tricuspid stenosis individually.
