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]
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.
Normal aortic valve is tricuspid. Five types of bicuspid valve are shown, with Type 1 being most prevalent. Bicuspid valve forms when the tissue surrounding one of the cusps (leaflets) of the valve fuse during fetal development. This developmental anomaly can have either negative or no effect on the individual.
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]

The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
Thus, a bicuspid valve is created which results in near-normal function of the aortic valve. The most reproducible concept is the creation of a bicuspid aortic valve with two normal commissures and two cusps. Tissue of the aortic valve is removed or detached from the aorta in places where it is clearly abnormal.
