Key result
Multimodality imaging provides more accurate moderate AS severity assessment and risk stratification than standard echo.
Why the study?
Moderate aortic stenosis was traditionally deemed a transitional and benign disease stage, but contemporary evidence shows substantial morbidity and mortality before progression to severe stenosis.
Integrating multimodality imaging and AI in moderate aortic stenosis improves diagnostic accuracy and risk stratification, potentially guiding earlier intervention in high-risk patients.

Multimodality imaging may refine moderate aortic stenosis assessment; leaves open prospective outcome trials before practice change.
BACKGROUND: Moderate aortic stenosis (AS) has traditionally been considered a transitional and relatively benign stage of valvular disease. Yet, contemporary evidence shows that it is associated with substantial morbidity and mortality even before progression to severe AS. This paper synthesizes current evidence on the limitations of standard echocardiography, highlights the role of advanced imaging and artificial intelligence, and outlines evolving strategies for risk stratification and clinical management. Multimodality imaging provides a more accurate assessment of disease severity beyond conventional echocardiographic parameters: computed tomography aortic valve calcium scoring, cardiac magnetic resonance, and 18 F-sodium fluoride positron emission tomography reveal early myocardial injury and identify rapid progressors. AI further enhances reproducibility and supports the development of emerging prognostic models. A staging approach that integrates ventricular, atrial, and right-sided involvement correlates more closely with clinical outcomes than valve metrics alone, enabling a more comprehensive characterization of disease burden. Although guideline-directed surveillance remains the standard strategy for most patients, selected high-risk individuals, particularly those with adverse remodeling, elevated biomarkers, or recurrent heart failure admissions, may benefit from earlier intervention. SHORT CONCLUSION: While waiting for the results of ongoing randomized trials cardiologist should implement all the imaging multimodality tools available in order to individuate patients in which an earlier treatment of moderate AS will more probably improve long-term outcomes.

Santangelo et al. (2026) conducted a review in Moderate aortic stenosis. Multimodality imaging vs. Standard echocardiography was evaluated. Multimodality imaging, including CT calcium scoring and cardiac magnetic resonance, provides a more accurate assessment of moderate aortic stenosis severity and risk stratification than standard echocardiography alone.
