These results have shed doubt over the efficacy of statin therapy for AS, although their potential efficacy at early stages of aortic valve disease remains possible. The spectrum of calcific aortic valve disease ranges from aortic sclerosis without obstruction to ventricular outflow to severe AS. Aortic sclerosis is common and is . Aortic valve disease constitutes a chronic, progressive disease over time. Mild fibro calcific leaflet changes progress to active bone formation on the aortic valve .
