Abstract 19719: Super Flexible Heart Replica With Vacuum Casting Technique Reproduces Real Structure and Texture of the Heart Fascinating Simulation Surgery in Complicted Congenital Heart Disease

Introduction: Precise understanding of 3D anatomy is crucial for successful surgical operation in complicated congenital heart disease (CHD). We have developed a new technology that reproduces accurate and extremely flexible polyurethane biomodels of complicated CHD suitable for simulation surgery and medical education. Hypothesis: A novel 3D printing technique employing with stereolithography followed by vacuum casting is suitable for simulation surgery in complicated CHD. Methods: Thirty five replicas of CHD were produced with this technique; diagnosis included tetralogy of Fallot, pulmonary atresia with ventricular septal defect, double outlet right ventricle, persistent truncus arteriosus, hypoplastic left heart syndrome, interrupted aortic arch, congenitally corrected transposition of the great arteries, and so on. Three-dimensional volumetric datasets of MSCT angiography of CHD were converted into standard triangulated language files to make plastic stereolithographic biomodels representing outer an...
