Figure 4 (A) Septal perforators (SP) in LAD, SP1 – smaller and SP2 – bigger; the area of LVS has only an inaccessible area; (B) – SP in proximal distance, SP – 1 in the LCA trunk, SP – 2 – dominant define very small LVS area; (C) – the presence of open LAA over LVS via the thickness of LAA and EAT; (D) the floor of LAA over LVS; (E) schematic distribution of left coronary subganglion with postganglionic autonomic fibers, yellow asterix- nerve fiber conecting with surface of the left auricle along the atrial branches of the circumflex left coronary artery; double yellow asterix – fibers from left coronary cardiac nerve. Abbreviations: LCA – left coronary artery, LAD – left anterior descending, SP – septal perforator, Cx – circumflex branch, GCV – great cardiac vein, Dx – diagonal branch, EAT – epicardial adipose tissue,
