The paper entitled “Normative Values of Aortic Arch Structures in Premature Infants” by Dijkema et al , published in the March 2017 issue of JASE (J Am Soc Echocardiogr 2017;30:227-32), has two corrections. On page 230, in Table 3 , the values in the “Standard error” column are incorrect. Also, the first value in the “ b ₂ ” column was incorrectly printed as “−1.258-E6.” Here, we present the corrected version of the table.
