Figure 5.

(A) A well-demarcated, non-transmural lesion in the left ventricle (MT, 3×). (B) Junction of fibrotic lesions and normal myocardium (H&E, 10×). (C) Thickening of arteriolar walls (black arrows) with well-preserved endothelial lining and spared lumen as seen within the core of an ablation lesion. Note: no thrombi in the vessels (MT, 10×). D) A transmural fibrotic lesion in right ventricle (MT, 2×). (E) Flat mesothelial cells lining of pericardium are seen to be well-preserved (MT, 40×). (F) Two well-preserved and viable nerve fascicles seen within fibrous tissue of an ablation lesion. H&E, haematoxylin and eosin; MT, masons trichrome.
