English: The aortic valve controls outflow of blood from the left ventricle of the heart through the aorta (valve is indicated within the yellow highlighted box). Normal aortic valve is tricuspid. Five types of bicuspid valve are shown, with Type 1 being most prevalent.
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]

A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century. [1] [2] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following on a single grid: Blood pressure. Aortic ...
Mitral valve or bicuspid valve, between the left atrium and left ventricle; Two semilunar valves to prevent the backflow of blood into the ventricle: Pulmonary valve, located at the opening between the right ventricle and the pulmonary trunk; Aortic valve, located at the opening between the left ventricle and the aorta.
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]
