The paper entitled “Multimodality Assessment of Ascending Aortic Diameters: Comparison of Different Measurement Methods” by Rodríguez-Palomares, published in the September 2016 issue of JASE (J Am Soc Echocardiogr 2016;29:819-26), has a correction. On page 825, in the third full paragraph, the first sentence should read as follows: “Because different imaging techniques are based on different spatial resolution, aortic wall thickness varies from 3.2 ± 1.6 mm by 2D TTE to 0.8 ± 0.7 mm by MDCT and 1.4 ± 1.2 mm by MRI.”
