A three-dimensional (3D) printed heart model based on contrast-enhanced MR angiography data was obtained in an 8-month-old male child with double-outlet right ventricle. The model could successfully show the spatial relationship between the aortic annulus, the pulmonary valve and the ventricular septal defect. The patient underwent complete intracardiac repair based on the 3D model. MR angiography images could be successfully used to create a true-size 3D heart model, which significantly helped in assessing the routability of the ventricular septal defect to the aorta, leading to successful intracardiac repair in our patient.
在一名患有右心室双出口的8个月大男童身上，基于对比增强磁共振血管造影数据获得了一个三维（3D）打印心脏模型。该模型能够成功显示主动脉瓣环、肺动脉瓣与室间隔缺损之间的空间关系。患者基于该3D模型接受了完全心内修复。磁共振血管造影图像能够成功用于创建真实尺寸的3D心脏模型，这对评估室间隔缺损通向主动脉的可操作性有显著帮助，从而使我们的患者心内修复成功。
