WebbBicuspid aortic valve is a type of abnormality in the aortic valve in the heart. In bicuspid aortic valve, the valve has only 2 small parts (leaflets), instead of the normal 3.

WebbFour valves control the flow of blood from the atria to the ventricles and from the ventricles into the two large arteries connected to the heart. These one-way valves have either two or three tissue flaps called leaflets that act as doors that open and close to ensure that blood flows only in the proper direction. WebbThe mitral valve is a small flap in the heart that stops blood flowing the wrong way. Problems with it can affect how blood flows around the body. The main problems that affect the mitral valve are: mitral valve prolapse – the valve becomes too floppy mitral regurgitation – the valve leaks and blood flows the wrong way
