Key result
Echocardiography guides primary aortic stenosis assessment, with CT and MRI resolving inconclusive cases.
Why the study?
Aortic stenosis is the most common cardiac valve lesion in adults with an increasing incidence, and accurate assessment of its severity is necessary for clinical decision-making.
Echocardiography is the primary diagnostic method for assessing aortic stenosis, with other imaging modalities playing a role in selected cases.
Reinforces echocardiography as first-line for aortic stenosis; leaves open prospective validation of CT/MRI integration.
Aortic stenosis (AS) is the most common cardiac valve lesion in the adult population, with an incidence increasing as the population ages. Accurate assessment of AS severity is necessary for clinical decision-making. Echocardiography is currently the diagnostic method of choice for assessing and managing AS. Transthoracic echocardiography is usually sufficient in most situations. Transesophageal echocardiography and stress echocardiography may also be utilized when there is inadequate image quality and/or discordance in the results and the clinical presentation. There is a role for other imaging modalities such as cardiac computed tomography, magnetic resonance imaging, and catheterization in selected cases. The following describes in some detail the role of these modalities in the diagnosis and assessment of AS.

Karim et al. (2022) conducted a review in Aortic stenosis. Multimodality imaging (Echocardiography, CT, CMR) was evaluated. Echocardiography is the primary diagnostic method for assessing aortic stenosis severity, with cardiac computed tomography and magnetic resonance imaging serving as valuable complementary tools in inconclusive cases.
