Echocardiographic Evaluation of Aortic Stenosis

  • Robert R. Moss


Echocardiography is a definitive tool for the assessment of aortic stenosis (AS). Echocardiographic assessment should include morphology of the aortic valve and related structures as well as a functional assessment of aortic stenosis severity. Functional assessment includes peak velocity of the AS jet, mean pressure gradient, and aortic valve area. Accurate assessment and reporting of aortic stenosis require a commitment to technical excellence as well as a sophisticated understanding of the limitations of functional parameters and potential for measurement errors. Echocardiograhers should provide an overall determination of aortic stenosis severity, determine suitability for treatment with transcatheter heart valve techniques, and resolve discrepant measurements whenever possible. Three-dimensional (3D) echo has an increasing role, especially in the transcutaneous heart valve context. Finally, AS needs to be viewed in the context of the function of the heart as a whole taking into account systolic and diastolic function, cardiac remodeling, non-aortic valvular heart disease, and the influence of associated cardiac conditions.
