Comparison of the measurements among 2D-TEE images, 3D-TEE images and 3D printed models of ASD
There was no significant difference in ASD size parameters among 2D-TEE images, 3D-TEE images and 3D printed models of ASD (allP >0.05). (Table 2 and Table3 )
Bland-Altman scatter plot showed that the ASD size parameters were concordant well between 3D printed models and 2D-TEE images, the limits of agreement for the maximum diameter, the minimum diameter and circular index of ASD were -1.17 and 1.33mm, -1.19and 1.34mm, -0.16 and 0.16. Points within the range of consistency boundaries account for 92.5%, 100% and 92.5%, respectively. (Fig. 5 ) Moreover, the agreement between the 3D printed models and 3D-TEE images measurements, which were assessed on the basis of Bland-Altman analysis, showed that the limits of agreement for the ASD parameters as the maximal diameter, minimal diameter, circular index and circumference were -1.16 and 0.95mm, -1.31 and 1.21mm, -0.14and 0.13, -2.9 and 2.4mm, respectively. The majority of plots (95%, 95%, 96.25% and 100%, respectively) fell within the limits of agreement. (Fig. 4 )
