PurposeThree-dimensional modeling and printing (3DMP) of anatomical structures from cross-sectional imaging data can enhance the understanding of spatial relationships in complex congenital heart defects. Partially due to the substantial financial, material and personnel resources required, 3DMP is not yet universally used. Here, we describe a workflow that addresses and eliminates these drawbacks.DescriptionThe workflow utilizes the open-source software “3D Slicer” (The Slicer Community) and “Blender” (Blender Foundation) for segmentation and post-editing of datasets. This approach enables the generation of virtual or physical 3D models. The physical models are printed using a standard fused deposition modeling printer.EvaluationThe financial challenges that likely constrain the wider use of 3DMP are largely addressed by this approach. However, the workflow still requires a considerable amount of time to manually segment the imaging data.ConclusionsThree-dimensional modeling and printing might improve planning and safety of congenital cardiac surgical treatment. Furthermore, it is a useful tool for education of parents and medical professionals. This workflow increases its suitability for routine use also in regions with low economic resources.

Nickel is a component of nitinol, an alloy used in several medical devices. Allergy to nickel may place patients at a high risk for severe hypersensitivity reactions. We report a rare case of a patient who developed severe ulcerative colitis ten years following closure of an atrial septal defect with the Amplatzer Septal Occluder device.
