- 3D Rapid Prototyping Heart Model Validation for Teaching and Training - A Pilot Project in a Teaching Institution Sivakumar Krishnasamy Raja Amin Raja Mokhtar Ramesh Singh Sivakumar Sivallingam Yang Faridah Abdul Aziz Vickneswaran Mathaneswaran Medicina Three Heart Models Imaging Anatomic Introduction: Rapid prototyping is a process by which three-dimensional (3D) computerized surface models are converted into physical models. In this study, a 3D heart bio model was created using the rapid prototyping method and the accuracy of this heart model was assessed by clinicians.Methods: The two-dimensional images of normal heart from gated computed tomography scan datasets were used to create a 3D model of the heart. The slices were then processed using the software BioModroid and printed with the 3D printer. The evaluation of the model was performed by a questionnaire answered by four cardiothoracic surgeons, 12 cardiologists, five radiologists, and nine surgical registrars.Results: Eighty-six percent of the anatomy structures showed in this model scored 100% accuracy. Structures such as circumflex branch of left coronary artery, great cardiac vein, papillary muscle, and coronary sinus were each rated 77%, 70%, 70%, and 57% accurate. Among 30 clinicians, a total of 93% rated the model accuracy as good and above; 64% of the clinicians evaluated this model as an excellent teaching tool for anatomy class. As a visual aid for surgery or interventional procedures, the model was rated excellent (40%), good (50%), average (23%), and poor (3%); 70% of the clinicians scored the model as above average for training purpose. Overall, this 3D rapid prototyping cardiac model was rated as excellent (33%), good (50%), and average (17%).Conclusion: This 3D rapid prototyping heart model will be a valuable source of anatomical education and cardiac interventional management. 2021 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398969709012 https://www.redalyc.org/journal/3989/398969709012/ https://www.redalyc.org/journal/3989/398969709012/html/ https://www.redalyc.org/journal/3989/398969709012/398969709012.epub https://www.redalyc.org/journal/3989/398969709012/movil 10.21470/1678-9741-2020-0433 en http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.5 Vol.36
