The aortic valve
is composed of valvular leaflets. It separates the aorta
from the left ventricle. When the aortic valve has only two valvular leaflets instead of three, it is called a bicuspid aortic valve. It is a genetic condition that constitutes a congenital malformation. It may cause a reflux of blood towards the aorta and lead to complications
if it is not detected in advance. The treatment, essentially surgical, consists of replacing defective valvular leaflets.
