Sievers Classification of Bicuspid Aortic Valve

Sievers Classification of Bicuspid Aortic Valve

The aortic valve typically consists of three leaflets i.e., posterior, left, and right cusps. However, in approximately 1 to 2% of population, an anatomical variant of aortic valve is present with two cusps. The bicuspid aortic valve is the most common congenital cardiac anomaly. It is mostly associated with left ventricular outflow tract obstruction. The bicuspid aortic valve is classified by Sievers Classification System. According to this classification, there are 3 types of bicuspid aortic valve: Type 0: No raphe is present Type I: One raphe is present Type II: Two raphes are present The complications of bicuspid aortic valve, such as subaortic stenosis and aortic insufficiency, are treated by aortic valve replacement Reference: https://www.sciencedirect.com/science/article/pii/S0022522307002371
