Introduction. The population frequency of a bicuspid aortic valve is â0.9% to 1.36%, 1â3 with a 2:1 male:female ratio. It is likely that the presence of a bicuspid aortic valve has a genetic basis, with the pattern of transmission in some families suggesting an autosomal dominant pattern of inheritance.
