Figure 2.

a/b Bland-Altman plots depicting differences in diameter measurement at the aortic sinus (a) and at the level of the ascending aorta (b) applying both the 2010 AHA/ACC guideline and the 2022 AHA/ACC guideline. Dotted red line: clinically acceptable limit of agreement for difference (+/–2 mm). Green line: agreement bias. The frequency of measurement differences outside the acceptable clinical agreement limit of difference (outside the range of the lower and upper dotted red line) was significantly lower using the 2022 AHA/ACC guideline
