1. IntroductionBicuspid Aortic Valve (BAV) is a congenital heart valve disease where the aortic valve has two leaflets instead of the normal three. BAV is one of the most common types of congenital heart disease in adults, with a prevalence of approximately 0.5% - 2% in the population [1]. BAV is often associated with aortic valve stenosis or insufficiency, as well as aortic dilation and aortic dissection [1] [2].
