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.

Population

Patients with moderate aortic stenosis

Design

Review

Key result

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.

Overview

Multimodality imaging may refine moderate aortic stenosis assessment; leaves open prospective outcome trials before practice change.

Key Points

Synthesize current evidence on the diagnostic limitations of standard echocardiography and highlight the role of advanced multimodality imaging and artificial intelligence in risk stratifying moderate aortic stenosis.
Reviewed diagnostic performance of conventional echocardiography alongside advanced imaging techniques, including CT calcium scoring, cardiac MRI, and 18F-sodium fluoride PET.
Evaluated artificial intelligence applications and cardiac damage staging frameworks incorporating ventricular, atrial, and right-sided chamber involvement.
Moderate aortic stenosis confers notable morbidity and mortality prior to transitioning to severe disease, challenging its traditional classification as a benign stage.
Multimodality imaging and AI tools detect early subclinical myocardial injury, measure calcification, and identify rapid progressors more effectively than standard valve metrics alone.
Comprehensive cardiac staging identifies high-risk individuals—such as those with adverse remodeling or recurrent heart failure—who may benefit from earlier valve intervention over routine surveillance.

Structured PICO

Population

Patients with moderate aortic stenosis

Intervention

Multimodality imaging (computed tomography, cardiac magnetic resonance, positron emission tomography) and artificial intelligence

Integrating multimodality imaging and AI in moderate aortic stenosis improves diagnostic accuracy and risk stratification, potentially guiding earlier intervention in high-risk patients.

Limitations

AI approaches in moderate AS are promising but remain investigational and should currently complement, not replace, expert clinical assessment.
Advanced imaging techniques like CMR-derived extracellular volume, PET, and 4D flow CMR are still investigational and require further prospective validation.
AI models face challenges such as dataset bias, limited generalizability across vendors, and dependence on human-labeled measurements.
