This paper aims to explore the feasibility of building a finite element model of left atrial diverticulum (LAD) using reverse engineering software based on computed tomography (CT) images. The study was based on a three-dimensional cardiac CT images of a atrial fibrillation patient with LAD. The left atrium and LAD anatomical features were accurately reproduced by using Geomagic Studio 12 and Mimics 15 reverse engineering software. In addition, one left atrial model with LAD and one without LAD were created with ANSYS finite element analysis software, and the validity of the two models were verified. The results show that it is feasible to establish the LAD finite element model based on cardiac three-dimensional CT images using reverse engineering software. The results of this paper will lay a theoretical foundation for further hemodynamic analysis of LAD.
本文旨在探讨利用基于计算机断层扫描（CT）图像的逆向工程软件构建左心房憩室（LAD）有限元模型的可行性。该研究基于一名患有LAD的房颤患者的三维心脏CT图像。通过使用Geomagic Studio 12和Mimics 15逆向工程软件精确再现了左心房和LAD的解剖特征。此外，利用ANSYS有限元分析软件创建了一个有LAD的左心房模型和一个没有LAD的左心房模型，并验证了这两个模型的有效性。结果表明，使用逆向工程软件基于心脏三维CT图像建立LAD有限元模型是可行的。本文的结果将为进一步对LAD进行血流动力学分析奠定理论基础。
