Three-Dimensional Printing of Cardiac Defects Using Stereolithography: A Single-Centre Experience

Three-dimensional (3D) printing is increasingly being used for congenital heart disease to allow an in-depth understanding of complex cardiac anatomy; however, access 3D hindered by lack access. This study investigated the feasibility rapid prototyping (RP)using a readily available on-site printer. Patients with anatomy were prospectively identified. All patients underwent ECG-gated computed tomography (CT) examination as part standard preprocedural work-up. Contrasting timing was modified maximum contrast enhancement relevant anatomy. Using CT dataset, mesh generated using open-source software. The models printed liquid resin stereolithography technology. To assess accuracy model produced, measurement mid ascending aorta compared taken from CT. Over 18-month period, 10 defects further assessment models. average processing time generate 6 hours and varied between 4 8 depending on size. aortic measurements had excellent correlation (33.4±3.3 mm vs 34±3.6 mm; Pearson 0.938; p<0.005). dataset via printers feasible enables appreciation anatomy, which helps guide patient management.
