With 2D echocardiography, the valve can be assessed in the Plax, where one sees the RCC and the NCC. In a normal aortic tricuspid valve closure line is then between the RCC and NCC is usually in the center of the aortic valve ring. Better one sees the aortic valve in the PSAXao However, where the three cusps in systole almost form a circle and diastole in an inverted Mercedes-Benz logo. Assessing the number of cusps is done in systole, because the valve is open, because in the closed position can be seen as a raphe purse line. With 3D echocardiography is now also wonderful to images. Off the aortic valve | With 2D echocardiography, the valve can be assessed in the Plax, where one sees the RCC and the NCC.

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.

==Stenosis== | |||
Some patients have no symptoms, sudden, unexpected death, the first phenomenon. Fatigue, shortness of breath and lack of oxygen during exertion, chest pain and dizziness and fainting during exercise are further symptoms. The left ventricle must be at a higher pressure aortic valve stenosis in order to generate gain. Blood in the aorta Arises in the long run by left ventricular pressure load. Depending on the severity and cause of the problem, a valve replacement may be indicated. | Some patients have no symptoms, sudden, unexpected death, the first phenomenon.

==Insufficiency== | |||
A serious aortic regurgitation caused a volume overload of the left ventricle. Since the blood that has been pumped out, it must be pumped out, once again touches the left ventricular overload and heart failure occurs. Patients complain of fatigue and shortness of breath. The valve, and possibly a part of the aortic arch, can be replaced. | A serious aortic regurgitation caused a volume overload of the left ventricle.
