Bicuspid aortic valves are the most common cardiac valvular anomaly, occurring in 1–2% of the general population. It is twice as common in males as in females. [23] Bicuspid aortic valve is a heritable condition, with a demonstrated association with mutations in the NOTCH1 gene. [24] Its heritability is as high as 89%. [25]
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 ...
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]
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 ...
The prevalence of aortic regurgitation also increases with age. Moderate to severe disease has a prevalence of 13% in patients between the ages of 55 and 86. [39] This valve disease is primarily caused by aortic root dilation, but infective endocarditis has been an increased risk factor.
Quadricuspid aortic valves are very rare cardiac valvular anomalies with a prevalence of 0.013% to 0.043% of cardiac cases [4] and a prevalence of 1 in 6000 patients that undertake aortic valve surgery. [5] There is a slight male predominance in all of the cases, and the mean age is 50.7. [5]
In 10% of cases, no mutation is found in either gene. For another member of the gene family, mutations in the Notch1 gene are associated with bicuspid aortic valve, a valve with two leaflets instead of three. Notch1 is also associated with calcification of the aortic valve, the third most common cause of heart disease in adults. [29] [30]
People who have had a coarctation of the aorta are likely to have bicuspid aortic valve disease. Between 20% and 85% of patients are affected by this disease. Bicuspid aortic valve disease is a big contributor to cardiac failure, which in turn makes up roughly 20% of late deaths to coarctation patients. [24]
