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]
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 ...
Causes include being born with a bicuspid aortic valve, and rheumatic fever; a normal valve may also harden over the decades due to calcification. [2] [1] A bicuspid aortic valve affects about one to two percent of the population. [1] As of 2014 rheumatic heart disease mostly occurs in the developing world. [1]
More than 50% of patients with aortic valve stenosis have a congenital heart abnormality called a bicuspid aortic valve. The aortic valve is normally three leaflets but when it is bicuspid it is made of two. [6] This increases the risk for aortic stenosis due to increased stress on the leaflets, calcium deposition, turbulent blood flow, and ...
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]
