Computational hemodynamics of the atrium facing wall of a patient-specific (PS) or spherical occluder. a) Fluid domains discretization with 441162 tetrahedron elements. Right superior pulmonary vein (RSPV), right inferior pulmonary vein (RIPV), left superior pulmonary vein (LSPV), and left inferior pulmonary vein (LIPV) are the inflow regions. The ostium is not visible from this surface view, but its position on the interior surface has been outlined using a yellow dotted line. The Chicken Wing morphology LAA has also been highlighted. The outflow region is the left ventricle, it has been cropped out. b) Model of left heart with PS occluder within the LAA, it has 472 741 tetrahedron elements. The wall shear stress contour of the atrial wall of the occluder has been overlaid on the model. c) Model of left heart with spherical occluder within the LAA, it has 408 667 tetrahedron elements. The wall shear stress contour of the atrial wall of the occluder has been overlaid on the model. Note the areas of dark blue on the outer edges. These are located where crevices have formed between the occluder and the atrial wall.
