Figure 2. A – section in the septal margin with LVS aspect, close to VAJ the depression above is the left sinus of Valsalva and conus vein (CV) trespassing in front of it. B – LVS after EAT removal red Asterix, white Asterix GVC over OM1, yellow Asterix GCV below to the OM2, behind Cx conus vein marked; C – dissection in L-R interleaflet trigon – thickness of LV and EAT was measured; Abbreviations:LVS = left ventricular summit; LAD = left anterior descending artery; LCA – left coronary artery; Cx = circumflex branch of left coronary artery; GCV = great cardiac vein; AIV = anterior interventricular vein; SP= septal perforator; OM = obtuse marginal; LAA = left atrial appendage; MV – mitral valve, VAJ – ventriculo aortic junction, CS – coronary sinus, RA – right atrium, LA – left atrium, AML – anterior mitral leaflet, LCC – left coronary cusp, CV – conus vein, LSPV – left superior pulmonary vein, LIPV – left inferior pulmonary vein, ACV – anterior cardiac veins.
