Correlation analysis for the measurements of 3D printed models
and occluder device size in ASD occlusion therapy
All of the 40 patients underwent ASD occlusion therapy in Renmin
Hospital of Wuhan University successfully. 20 patients had round shape
ASD and 20 patients had oval shape ASD. There was significant
correlation between 3D printed models and the occluder device actually
applied intraoperative in the maximum diameter, the minimum diameter and
circumference data, whose Pearson correlation coefficient were
0.88,0.87,0.90, respectively(all p<0.05) . Compared with the other
three parameters, circumference of the 3D printed models showed a more
significant correlation with the occluder device size (p<0.05).The 3D
printed ASD size parameters and the intraoperative occluder size
parameters were shown in Table 4 .
