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.

Regression analysis of arch dimensions related to BW

	Intercept	b 1	b 2	b 3	Standard error	R 2
Ascending aorta	2.332	0.004	−1.258E-6	2.111E-10	0.62	0.427
Transverse aorta	3.910	−0.001	1.087E-6	−1.321E-10	0.61	0.305
Isthmus	2.994	−0.001	1.360E-6	−2.8381E-10	0.79	0.109
Descending aorta	4.131	−0.002	2.799E-6	−7.4607E-10	0.78	0.177
