Figure 4 : Panel a: Fiji-software-processed immunohistological image of an ablated superior vena cava of pig 4 with tissue ink applied at the endothelial side at the level of the heating spot, indicated by the arrows in panel b, scale bar of panel a=1mm.

Panel b: Higher magnification of the delimited area in panel a, indicating both a non-ablated region (1) and ablated region (2), scale bar=100μm.
Panel c: Highly enlarged detail of panel a, demonstrating an insulating barrier consisting of charred (1) and connective tissue (2) between the heating area (indicated by the blue ink) and the intact myocardial tissue (3), scale bar=100μm.
