OBJECTIVES: To evaluate whether three-dimensional (3D) printed models can be used to improve interventional simulation and planning in @entity1 with @entity8521 . Background: Stenting of a hypoplastic transverse arch is technically challenging, and complications such as stent migration and partial obstruction of the origin of the head and neck vessels are highly dependent on operator skills and expertise. Methods: Using magnetic resonance imaging (MRI) data, a 3D model of a repaired @entity1498 of a 15-year-old @entity1 with @entity8521 was printed. Simulation of the endovascular stenting of the hypoplastic arch was carried out under fluoroscopic guidance in the 3D printed model, and subsequently in the @entity1 . A Bland-Altman analysis was used to evaluate the agreement between measurements of aortic diameter in the 3D printed model and the @entity1 's MRI and X-ray angiography. Results: The 3D printed model proved to be radio-opaque and allowed simulation of the stenting intervention. The assessment of optimal stent position, size, and length was found to be useful for the actual intervention in the @entity1 . There was excellent agreement between the 3D printed model and both MRI and X-ray angiographic images (mean bias and standard deviation of 0.36        0.45 mm). Conclusions: 3D printed models accurately replicate @entity1 ' anatomy and are helpful in planning endovascular stenting in transverse arch @entity509 . This opens a door for potential simulation applications of 3D models in the field of catheterization and cardiovascular interventions.    2015 Wiley Periodicals, Inc.
