Key result
Multimodality imaging approaches, including echocardiography, CT calcium scoring, CMR, and 18F-NaF PET, are valuable for assessing disease activity and optimizing intervention timing in severe aortic stenosis.
Why the study?
Imaging is fundamental for initial diagnostic work-up, follow-up, and selection of timing and type of intervention in aortic stenosis, alongside clarifying disease pathophysiology and progression.
Multimodality imaging provides a comprehensive assessment of both valve severity and the myocardial response, extending beyond conventional echocardiography to guide clinical management in severe aortic stenosis.
May guide intervention timing in severe aortic stenosis; leaves open need for prospective outcome trials.
Aortic stenosis is the most common type of valvular heart disease. Aortic stenosis is characterized both by progressive valve narrowing and the left ventricular remodeling response that ensues. In aortic stenosis, therapeutic decision essentially depends on symptomatic status, stenosis severity, and status of left ventricular systolic function. Imaging is fundamental for the initial diagnostic work-up, follow-up, and selection of the optimal timing and type of intervention. Noninvasive imaging has played a pivotal role in enhancing our understanding of the complex pathophysiology underlying aortic stenosis, as well as disease progression in both the valve and myocardium. The present review provides the application of multimodality imaging in aortic stenosis.

Park et al. (2019) conducted a review in Severe Aortic Stenosis. Multimodality imaging was evaluated. Multimodality imaging approaches, including echocardiography, CT calcium scoring, CMR, and 18F-NaF PET, are valuable for assessing disease activity and optimizing intervention timing in severe aortic stenosis.
