Variability in Echocardiographic Ascending Aortic Diameters due to Image Acquisition by Different Sonographers

Aortic dilatation carries an increased risk of aortic dissection, with high mortality and morbidity rates.1 To diagnose aortic dilatation and determine the need for preventive intervention, reliable measurement of the aortic diameter is crucial.2,3 The ascending aortic (AA) diameter can be assessed with different imaging modalities: computed tomography (CT), cardiovascular magnetic resonance imaging (CMR), and echocardiography. Because echocardiographic images are handmade by the sonographer, echocardiography is more operator dependent than CT and CMR, which induces additional variability in aortic measurements.
