<p>The left atrium (LA) has a complex anatomy with heterogeneous wall thickness and curvature. We include 3 patient-specific anatomical FE meshes with rule-based myofiber directions of each of the anatomies included in our study ("The impact of wall thickness and curvature on wall stress in patient-specific electromechanical models of the left atrium", BMMB, 2020, <a href="https://pubmed.ncbi.nlm.nih.gov/31802292/">https://pubmed.ncbi.nlm.nih.gov/31802292/</a>).<br>
Additionally we include<br>
- a model with Gaussian noise added (mean 0 um , standard deviation 100 um) to the initial geometry of patient case 3 and subsequently smoothed using ParaView; and <br>
- a mesh with a constant wall thickness of 0.5 mm generated based on the endocardial surface of patient case 3.</p>
<p>The meshes are given in VTK file format (.vtu) and in the binary format used for the Cardiac Arrhythmia Research Package simulator, see <a href="https://carpentry.medunigraz.at/carputils/index.html">https://carpentry.medunigraz.at/carputils/index.html</a> and <a href="https://opencarp.org/">https://opencarp.org</a>. Here, for each of the geometries, we include a list of nodal coordinates (.bpts file), a list of triangular elements (.belem file), fiber fields (.blon file), surface files (*.surf files), and surface points (*.surf.vtx files).<br>
Surface files include the endocardium (laendo.surf), the epicardium (laepi.surf), the mitral valve ring (mitralvv.surf), the pulmonary outlet rings (pulvring.surf) and lids (lid*.vtx) to close the five in- and outlets of the LA.</p>
<p>Using the open source mesh utiliy "MeshTool" (<a href="https://bitbucket.org/aneic/meshtool/src/master/README.md">https://bitbucket.org/aneic/meshtool/src/master/README.md</a>)<br>
meshes can be manipulated or converted to VTK or EnSight file formats.</p>
