3D printed model used to produce custom stent for 18 month old with pulmonary atresia

Using a 3D printed model of the patient's narrowed pulmonary artery, a Children's Hospital Los Angeles (CA, USA) cardiologist was able to modify an existing stent to repair a baby's artery. When a baby's pulmonary artery started to narrow again after a repair, Pediatric Interventional cardiologist Frank Ing, Children's Hospital Los Angeles (CA, USA), utilized a 3D printed model to determine the perfect sized stent needed to keep the right artery open. As the narrowing was approximately 9mm, it was necessary for doctors to customize the stent to fit into the small space. In order to perfect their measurements before...
