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.
