房室结动脉
锐缘支
后降支
冠状动脉解剖---左优势型与右优势型与均衡性
• 右优势型（ 85% ）：RCA走行于右房室沟，到达后十字交叉处，在后十字交叉或近后十字交叉处分出后降支后，向左室隔面走行并发出1个或多个左室后支后终止。
• 左优势型（ 8% ）：即左回旋支优势，左回旋支粗大，除发出钝缘支外，还发出左室后支和后降支，而RCA 细小，未达到后十字交叉处。
左室的血液供应
❖ 前间壁、前壁—LAD ❖ 前侧壁—LAD（对角支）和LCX（钝缘支） ❖ 后侧壁—LCX（RCA) ❖ 下壁—多为RCA（后降支），亦可为LCX，偶有部分来

❖ 后壁—RCA（左室后侧支）和/或LCX ❖ 室间隔：前上2/3和心尖部—LAD，后下1/3—RCA
