if the valves failed then the blood would go in the wrong direction.
The mitral valve (or bicuspid valve) is the left atrioventricular valve. That means the left atrium would receive blood flow from the left ventricle (the wrong direction) if there was a regurgitation in that valve.
valves help prevent blood from flowing in the wrong direction by opening and closing at the right time to let the heart pump blood effectively.
There are two ways that blood is kept flowing in the same direction. The heart is pumping it in that direction, and blood vessels contain valves which prevent blood from flowing in the wrong direction.
