  2. Aortic stenosis - Wikipedia

    en.wikipedia.org/wiki/Aortic_stenosis

    Aortic stenosis is most commonly caused by age-related progressive calcific aortic valve disease (CAVD) (>50% of cases), with a mean age of 65 to 70 years. CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. [22]

    Aortic valve stenosis is the most common cause of LVOTO. Aortic valve stenosis means the aortic valve has narrowed and is not opening freely. The aortic valve opens to allow blood to flow from the left ventricle to the aorta. Stenosis here leads to a narrowing of the passage for blood to flow out of the left ventricle, thus a LVOTO.

    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.

    Pulmonary stenosis. This is a type of heart valve disease in which the pulmonary artery, the vessel connecting the heart to the lungs, is too narrow or thick. Atrial septal defect.

  6. Bicuspid aortic valve - Wikipedia

    en.wikipedia.org/wiki/Bicuspid_aortic_valve

    A bicuspid aortic valve may cause the heart's aortic valve to narrow (aortic stenosis). [6] This narrowing prevents the valve from opening fully, which reduces or blocks blood flow from the heart to the body. In some cases, the aortic valve does not close tightly, causing blood to leak backward into the left ventricle. [10]

  7. Valvular heart disease - Wikipedia

    en.wikipedia.org/wiki/Valvular_heart_disease

    Calcification of the leaflets of the aortic valve is a common with increasing age, but the mechanism is likely to be more related to increased lipoprotein deposits and inflammation than the "wear and tear" of advance age. [17] Aortic stenosis due to calcification of tricuspid aortic valve with age [16] comprises >50% of the
