Aortic stenosis; In the center an aortic valve with severe stenosis due to rheumatic heart disease. The valve is surrounded by the aorta. The pulmonary trunk is at the upper right. The right coronary artery, cut lengthwise, is at the lower left. The left main coronary artery, also cut lengthwise, is on the right. Specialty: Cardiac surgery ...
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...
Usually, the aortic valve opens to about 3-4 cm2, but with stenosis it can become less than 1 cm2. This is usually caused by mechanical stress over time, which damages endothelial cells around the valves, causing fibrosis and calcification, which hardens the valve and makes it more difficult to open completely.
Aortic stenosis due to calcification of tricuspid aortic valve with age [16] comprises >50% of the disease. Aortic stenosis due to calcification of a bicuspid aortic valve [16] comprises about 30-40% [15] of the disease. Hypertension, diabetes mellitus, hyperlipoproteinemia and uremia may speed up the process of valvular calcification. [15]
Aortic valve repair or aortic valve reconstruction describes the reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of aortic aneurysm, or less frequently for congenital aortic stenosis. [8]
