Echocardiography will remain the mainstay of imaging in the initial assessment. Aortic valve computed tomography (CT) calcium score is an alternative method in assessing aortic stenosis severity, particularly in patients with discordant echocardiographic findings. In the early stages of aortic stenosis, hybrid positron emission tomography/computed tomography (PET/CT) may complement assessment of disease progression by aortic valve CT calcium score and to monitor efficacy of novel anti-calcification therapies. In the later stages, the focus shifts to the myocardium with the aims of identifying patients with myocardial fibrosis using cardiovascular magnetic resonance, to help guide the timing of aortic valve replacement.
