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.
The mitral or bicuspid valve has two flaps.

Both types of semilunar valve, aortic and pulmonary, have three cusps. These flaps make sure that blood only flows in one direction.

Bicuspid valve.. a birth defect of the aortic valve.
No. When the flaps of the aortic valve close, they prevent the flow of blood into the ventricle. The flaps of the atrioventricular valves close to prevent the flow of blood back into the atria.
Aortic valve replacement is necessary when the aortic valve has become diseased. The aortic valve can suffer from insufficiency (inability to perform adequately) or stenosis.
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.

The blood flows through the aorta after exiting the left ventricle through the aortic valve.
There are three cusps in the aortic valve; the right, left and noncoronary cusps The aortic semilunar valve is composed of three cusps and opens only when the left ventricle contracts. I hope this helps
The left Mitral atrioventricular valve is bicuspid (two flaps).
because the aortic valve is not functioning properly, i.e. prolapse
