Calcified Aortic Valve Disease

The aim of this clinical trial is to understand whether the drug PCSK9 inhibitor can slow the progression of calcific aortic valve disease and to understand the safety of the drug. The primary objective of the study was to evaluate whether PCSK9 inhibitors could delay the progression of aortic stenosis in patients with aortic stenosis. Secondary objectives: 1) To evaluate whether PCSK9 inhibitors can delay the progression of valve calcification in patients with aortic stenosis;2) To evaluate whether PCSK9 inhibitors can reduce long-term adverse events in patients with aortic stenosis;3) To evaluate the effect of PCSK9 inhibitors on circulating Lp(a) levels in patients with aortic stenosis.
