Overview

Aortic stenosis can be categorized under two methods of causation: acquired and congenital. Research regarding the influence of preventative therapies on causation is mixed. More research is needed evaluating the role of preventative interventions, such as cholesterol lowering therapies, on the progression of disease onset.

Genetics

Congenital bicuspid valve is the most frequent form of congenital heart disease affecting approximately 1-2% of the population. 1/3rd of Supravalvular Aortic Stenosis cases are transmitted as an autosomal dominant trait as 60% of patients with supravalvular obstruction have Williams syndrome (supravalvular obstruction, intellectual impairment and facial abnormalities).
