11 PRINTING 3D MODELS OF THE HEART: CAN IT HELP IN UNDERSTANDING THE COMPLEX ANATOMY?

Abstract

Abstract The use of 3D printing in the medical field is widespread especially in the dental clinic as a support to orthodontic / implant therapy. In the training of personnel relating to cardiological diagnostic methods, can it be useful to shorten the learning curve of human anatomy? A light-curing liquid resin 3D printer was used to obtain anatomical models that faithfully reproduce the real anatomy of the individual patient. The starting model was obtained from CT with contrast medium performed on patients. Depending on the diagnostic question, CT may contain complete information on both the arterial circulation and the venous circulation of the heart and the epiaortic vessels. From this information a 3D surface reconstruction is obtained which, once reworked, can be used directly for printing. The model size is limited by the print volume of the printer which may vary depending on the printer model. The model to be printed obtained from CT acquisitions the 3D model will be the representation of the lumen of the vessels and cavities of the heart. The models obtained faithfully represent the anatomical reality of the patient who underwent CT with contrast medium. Actual size is affected by the print volume size of the printer model. In my experience in university teaching, the models obtained with 3D printing have been found to be very useful for understanding the complex spatial configuration of the anatomy of the heart and great vessels
