心臟主要是兩條冠狀動脈(左冠狀動脈LCA和右冠狀動脈RCA)包含三大條血管(左前降枝,左迴旋枝及右冠狀動脈)
組成供應心臟所需之含氧血和養分的血流。左冠狀動脈LCA:左冠狀動脈主幹(Left Main) 分為
1. 左前降枝- LAD,包含 diagonal branch及septal br.
2. 左迴旋枝- LCx ,包含 OM1及OM2 branch.
右冠狀動脈RCA,包含 AM, atrial branch, PDA及 PL branch

LM (Left Main) 指左冠狀動脈主幹LAD-P(left anterior descending proximal part) 指左前降枝前段LAD-M(left anterior descending middle part) 指左前降枝中段LAD-d (left anterior descending distal part) 指左前降枝後段LCx-P (left circumflex proximal part) 指左迴旋枝前段LCx-M (left circumflex middle part) 指左迴旋枝中段LCx-d (left circumflex distal part) 指左迴旋枝後段
右冠狀動脈心導管影像
RCA-P (right coronary artery proximal part)指右冠狀動脈前段
RCA-M (right coronary artery middle part)指右冠狀動脈中段
RCA-d (right coronary artery distal part) 指右冠狀動脈後段
RCA-PDA (posterior descending branch)指右冠狀動脈後端分支
RCA-PL (posterolateral branch)指右冠狀動脈後面分支
