Aortic Valve Stenosis Planimetry by Means of Three‐Dimensional Transesophageal Echocardiography in the Real Clinical Setting: Feasibility, Reliability and Systematic Deviations

Abstract

Reliability of AVA planimetry by 3DTEE in comparison with the calculation by TTE is good, but 3DTEE underestimates slightly the measurement. Feasibility of the technique is good but independently affected by valvular calcification. Inconsistent classification of AVS severity as graded by AVA or mean systolic gradient is observed in the overall population and in patients with preserved systolic function.
