MODELAGEM 3D DE IMAGENS DE ECOCARDIOGRAMAS PARA IMPRESSÃO DEVALVAS MITRAIS ESPECÍFICAS.

Abstract

Anatomical structures present in atria and ventricles can be affected by changes that compromise the cyclical functioning of the human heart. However, the proper planning of possible interventionprocedures to correct these changes is made from the use of different modalities of imaging exams. Thus, computed tomography, magnetic resonance and echocardiography are among the imaging methods available by professionals to obtain the necessary information before performing each procedure. The echocardiogram gains special attention due to its greater global availability in relation to the other methods mentioned, as it can provide three-dimensional images of cardiac structures in a more practical, safer and lower cost manner. In this approach, there is an increase in the number of scientific publications aimed at a new practice of visualization of imaging exams that can provide a better planning of various surgical strategies. Thus, the use of printing models in three dimensions (3D printing) has been the subject of research, as these techniques allow a more accurate view of what the surgeon should find when performing the procedure. Therefore, the purpose of this work is to present a 3D printing technique of specific mitral valves for each individual submitted to transesophageal echocardiograms. Therefore, different computational techniques were applied to obtain the exams, convert the files obtained in the exams to files to be modeled and processed by different software and, finally, the impression of the specific mitral valves of each participant. Thus, this work performed the 3D printing of a total of 6 samples, in which each all of them were achieved by the use of free softwares.
