Aortic valve calcification (AVC) is one of the major causes of aortic stenosis (AS), and its pathogenesis is related to inflammation infiltration, lipid deposition, endothelial damage, calcification osteogenesis and angiogenesis. Previous studies have shown that AVC is associated with the severity of AS, the incidence of cardiovascular events, mortality, and surgical outcomes. The quantitative analysis of AVC using imaging methods not only has diagnostic value for AS, but also has guiding significance for the selection of surgical timing, assessment of surgical risk, and prognosis prediction. This article comprehensively elaborates on the methods and values of evaluating AVC using echocardiography, CT, and positron emission tomography.
