Background : 3D printing technology is very useful for training of various surgical skills in the medical field. Surgical procedures need a full knowledge of human anatomy and structural relations of various anatomical structures. This comprehensive knowledge is traditionally taught by the preparation of human cadavers in the preclinical studies of medical school and then put into practice and intensified during real surgery. Surgical practice only during the real surgery might not be enough for trainees. We developed the aortic valve replacement simulator with using 3d printing based on the real patient’s CT images.
Methods : After converting the CT image of patient’s aorta who underwent aortic valve replacement surgery into a 3D image using Mimics Base version 16 (Materialize, Leuven, Belgium), the segmented 3D image was stored as a stereolithography (STL) file. The file was then sent to a 3D printer (uPrint, Stratasys Ltd, MN, US) and a 3D model of the aorta was printed. This printed model was hard one because we used Acrylonitrile-Butadiene-Styrene (ABS) as a modeling material. On this model, we coated the liquid silicone and made the hollow elastic model of aorta. With this elastic model, we tested the feasibility of suturing and aortic valve replacement procedure practice.
Results : With this model, we could do a leaflet resection, suturing on annulus, and aortic valve replacement practice without cut-through. The tactile sensation of aorta was very similar with the real aorta during suturing.
Conclusion : An aortic valve replacement simulator with using 3D printing would be helpful for cardiothoracic trainees to improve their surgical skills.
