Elderly gentleman with atrial fibrillation being evaluated for left atrial appendage occlusion using a transcutaneous catheter-deployed device: example of ‘Basic’ 3D printing. CT data (not shown) was segmented, after which computer aided design was used to arrive at a Final Anatomic Representation surface mesh file (not shown). Transparent, flexible 3D printed part as the Patient Specific Realization of the surface mesh file. The left atrial appendage occlusion device is shown near the orifice of the appendage. Anatomic models have high utility for this clinical indication when compared to 3D visualization alone. Ravi P et al. J Am Coll Radiol. 2023 Feb;20(2):193–204.
