材料和方法结构正常的心脏和动脉干心脏的3D打印模型(图E1)购自多伦多儿童医院。简而言之，心电门控计算机断层扫描被用来获取成像数据，这些成像数据被后处理，用于使用基于阈值的分割和计算机辅助设计过程进行3D建模。14、15、16然后使用PolyJet光致聚合物(TangoPlus，Stratasys Ltd)打印模型，该聚合物模拟心脏组织，并经验证可用于手术模拟。14例部分心脏移植手术是在多次迭代中开发的，以确定和完善关键的手术步骤(图1)。
Materials and MethodsThe 3D printed models (Figure E1) of structurally normal hearts and hearts with truncus arteriosus were purchased from the Hospital for Sick Children in Toronto. Briefly, electrocardiographically gated computed tomography scans were used to acquire imaging data that were postprocessed for 3D modeling using threshold-based segmentation and computer-aided design processes. 14, 15, 16 The models were then printed using a PolyJet Photopolymer (TangoPlus, Stratasys Ltd) that emulates cardiac tissue and is validated for use in surgical simulation. 14 Operations for partial heart transplantation were developed in multiple iterations to identify and refine critical surgical steps (Figure 1).
