The mitral valve and the tricuspid valve are known as the atrioventricular valves because they lie between the atria and the ventricles. [1] In normal conditions, blood flows through an open mitral valve during diastole with contraction of the left atrium, and the mitral valve closes during systole with contraction of the left ventricle. The ...
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
On the left are two standard 2D views (taken from the 3D dataset) showing tricuspid and mitral valves (above) and aortal valve (below). The atrioventricular valves are the mitral valve, and the tricuspid valve, which are situated between the atria and the ventricles, and prevent backflow from the ventricles into the atria during systole.

Blood flow through the valves 3D echocardiogram viewed from the top, with the upper part of the ventricles removed and the mitral valve clearly visible (cusps are not clear and pulmonary valve not visible). On the left are two, two-dimensional views showing tricuspid and mitral valves (above) and aortic valve (below).
The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).
The mitral and tricuspid valves, also known as the atrioventricular, or AV valves, open during ventricular diastole to permit filling. Late in the filling period the atria begin to contract (atrial systole) forcing a final crop of blood into the ventricles under pressure—see cycle diagram.
The right fibrous trigone is the strongest part of the skeleton. It lies to the right of the aortic valve and connects it with the mitral and tricuspid valves. It is pierced by the bundle of His. Lastly, the aortomitral curtain is also a part of the fibrous skeleton; it is formed by fibrous tissue connecting two of three of the aortic valve ...
