Bicuspid aortic valve | |||
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. | |||
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. | |||
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. | |||

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. | |||
