- LA, left atrium; CT, computed tomography; LAWT, left atrial wall thickness; AF, atrial fibrillation; PeAF, persistent atrial fibrillation; PAF, paroxysmal atrial fibrillation
- In the previous study, if the region was divided into sub-regions, a similar region was selected. The selected regions are as follows: (i) Left lateral ridge; (ii) Middle-superior posterior; (iii) Middle floor; (iv) Mitral Isthmus; (v) Middle Posterior; (vi) Middle floor; (vii) Posterior right superior PV-LA junction; (viii) Anterior left superior; PV-LA junction; (ix) Right floor; (x) right low anterior PV antrum; (xi) Left low anterior PV antrum
