Abstract
An observational examination of the heart was performed in the Department of Anatomy, during the routine autopsy of a 89-year-old man. The heart was fixed in 10% formalin and an analysis of arterial vasculature was performed (used morphometric abbreviations below [mm]: L - length; D - diameter of origin). Trifurcation of the left main coronary artery (LMCA; L=17.4; D=8.1) was observed during the study, which originated in the left aortic sinus and was followed by three branches: proper left anterior descending artery (pLAD; L=11.2; D=7.4), intermediate branch (IMB; L=98.6; D=3.5) and left circumflex artery (LCxA; L=104.2; D= 4.9), respectively. In the pLAD division, there was noted LAD1 (long) which was running in the interventricular septum (L=32.2) and further in the subepicardial segment (L=109.3) in the anterior interventricular groove towards the apex (AC) (LAD1; L=141.4; D=6.3) and LAD 2 (short) running subepicardial in the anterior interventricular groove in the AC direction (LAD2; L=68.4; D=3.2). 4 diagonal branches (DB) and 9 septal perforator (SP) were observed in the course of LAD1; regarding the LAD2 there were 6 SP only. It is worth noting that the first SP supplying of the interventricular septum came f...
