Bicuspid aortic valve is the most common cardiac valve abnormality. Here are two leaflets fused at the development. A bicuspid aortic valve occurs in 1-2% of the population and twice as often in men as in women. | Bicuspid aortic valve is the most common cardiac valve abnormality.

A bicuspid aortic valve can be hereditary, both familial clustering and isolated valve defects are documented. The incidence of bicuspid aortic valve may reach 10% in certain families. A bicuspid aortic valve is often associated with other congenital heart defects, including coarctation of the aorta. Usually there is a fusion between the LCC and RCC (70%). In many cases, the bicuspid aortic valve do not cause any problems. Later in life, the valve will calcify early causing a stenosis occurs and possibly leak through malcoaptatie of the affected cusps. | A bicuspid aortic valve can be hereditary, both familial clustering and isolated valve defects are documented.
