Many anatomists have attempted to classify coronary circulation for the large variety of coronarybranches, their variable course, and range of anatomical areas supplied with blood. The first classificationwas introduced by Banchi [4] in 1904. He observed the dominance of the right coronary arteryin 17%, the left coronary artery in 10%, and the co-dominant type in 73% of examined hearts...

The left coronary artery presents wide variability in its morphology with regard to length, calibre and the number of branches of its trunk. The left coronary artery trunk (LCAT) divides in several ways; it bifurcates, producing the anterior interventricular branch (AIB) and the circumflex branch (CxB), trifurcates, producing AIB, CxB and a diagonal branch (DB),...

The arterial supply of most of the heart is dependent on the patency of the left coronary artery (LCA) [19]. On reaching the atrioventricular groove, the LCA usually divides into 2 (anterior interventricular artery [AIA] and left circumflex [LCx] artery) or less frequently into the AIA, LCx, and one or more “additional” terminal branch/es (ATBs). It is these ATBs (1 or more) that are the topic of investigation and discussion in this paper. There is great variability in the morphometric and morphologic parameters of the LCA with regard to its length, calibre, angle of division, and branching pattern [7]...
