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 .
