Simulation of atrial fibrillation sustained by a microanatomic reentry and the simultaneous EGM registered with a unipolar electrode at 2mm and 6mm from the pectinate muscle, respectively.

We have developed a new atrial model that improves our previous 3D model of the human atria. The new model (available online at Download Media section) has enhanced anatomical and functional heterogeneity and the detailed regional description of fibre direction. The resulting computational finite element model is a multi-layer mesh with a homogeneous wall thickness between 600 and 900 μm (754.893 nodes and 515.010 elements), built with linear hexahedral elements with regular spatial resolution of 300 µm. Following a histological analysis, the model was manually divided into 21 regions. However, for the detailed description of fibre orientation, some regions were further subdivided into a total of 53 sub-regions. The model also includes the preferential conduction bundles (Fig. 2 row 2), which are the CT, PMs, BB with right (BBR) and left (BBL) sides and the LFO between both atria. Atrial fibre orientation was analysed in detail to determine the number and location of regions with a common fibre organization (Fig. 2 row 3). This orientation was assigned to each region as the cross product between the principal region-defining vector direction and the normal to the external surface of each element belonging to that region.
