Abstract:
Objective To preliminary explore the feasibility of three‐dimensional transesophageal echocardiography ( 3D‐T EE) as images data source for 3D printing model by comparing the 3D‐T EE with CT of the aortic root Digital Imaging and Communications in M edicine ( DICOM ) data into 3D printing models respectively . Methods Fifteen patients w ho underwent surgical aortic valve replacement in the hospital were enrolled ,and the aortic root 3D‐T EE and CT DICOM data were obtained in perioperative . T he images were imported into M imics software to generate digital model standard tessellation language file ,and to print the aortic root models by 3D printer . T he structural morphology of both 3D‐T EE and CT models were qualitatively evaluated respectively . T he aortic annular area ,perimeter ,maximal diameter and minimal diameter of the original data , digital model , model and aortic valve replacement were quantitatively evaluated ,and the consistency of each parameter value were analyzed . T he mean diameter of 3D‐T EE and CT model were calculated . T he correlation of mean diameter with the number of replacement was analyzed . Results ①Both 3D‐TEE and CT images data were successfully printed into 3D models ,and the positive rate of aortic valve structure were 93 .3% ( 14/15) and 80 .0% ( 12/15) respectively . ②T he measured values of the aortic annular 3D‐T EE and digital model were smaller than CT ,CTdigital model and replacement ( P＜0 .05) ,and the measurement consistency among groups was high . ③ T he parameter values of 3D‐T EE model were smaller than CT model ( P ＜0 .05 ) ,and the measured values were all within the consistency range . T he mean diameters were highly correlated with the replacement values ( r ＞ 0 .95 , P ＜ 0 .05 ) . Conclusions 3D printing aortic root model based on 3D‐TEE image data is of high feasibility .
