3D打印技术在结构性心脏病中的应用

Application of three dimensional printing technology in structural heart disease

目的:探讨3D打印技术制作心脏三维模型在结构性心脏病诊疗中的应用价值。方法:将心脏增强CT图像导入Mimics软件进行三维重建,采用3D打印机打印出1∶1心脏模型。根据3D打印模型测量所需数据并制定手术方案。结果:4例心脏3D打印模型均制作成功,包括1例心肌梗死后室间隔穿孔合并心尖部室壁瘤、1例心肌梗死后室间隔穿孔、1例升主动脉瘤和1例法洛四联症。打印的模型能显示心脏各结构的空间位置及毗邻关系。结论:心脏增强CT图像可以打印出完整的心脏三维模型,为结构性心脏病提供术前模拟,对提高手术成功率有较大帮助。

Objective:To explore the value of three-dimensional heart model made by 3D printing technology in the diagnosis and treatment of structural heart disease. Methods:The data of the series of heart sections scanned by CT were imported to Mimics soft for the 3D reconstruction.Then the formation of 1∶1 model of heart was printed.Data was collected and surgical plan was made according to the heart models. Results:We successfully made four cardiac 3D printing models,including one case of ventricular septal perforation with apical ventricular aneurysm after myocardial infarction,one case of ventricular septal perforation after myocardial infarction,one case of ascending aortic aneurysm and one case of tetralogy of Fallot.The printed model can show the spatial location and adjacent relationship of the structures of heart. Conclusions:CT pictures can be converted into a 3D heart model.3D heart models can provide simulating intervention therapy on the models and improve operation successful rate.
