Left atrial wall thickness can be robustly measured using a Laplace equation over a finite element mesh, providing a potential tool to guide future radiofrequency ablation procedures for atrial fibrillation.
Left atrial wall thickness can be measured robustly and efficiently across the whole left atrium using a solution of the Laplace equation over a finite element mesh of the left atrium. Further studies are indicated to determine whether the integration of LAWT maps into pre-existing 3D anatomical mapping systems may provide important anatomical information for guiding radiofrequency ablation.
Bishop et al. (2015) studied this question.
