冠状动脉瘘——罕见高位对角支右心室瘘1例

Coronary artery fistula,a rare case of the fistula between high diagonal branch and right ventricle

冠状动脉瘘（coronary artery fistulae,CAF）又称冠状动静脉瘘,是罕见的冠状动脉畸形,主要表现为冠状动脉主支或其分支与心腔或其他动静脉血管之间存在异常交通,文献报道绝大多数CAF是由于胚胎心血管系统发育过程中,心肌内小梁间隙未形成毛细血管网所致的先天性畸形,仅约0.44%病例可由治疗先天性心脏病过程中的各种手术操作等后天因素所致。

This paper reported a rare case with coronary artery fistula,high diagonal branch to right ventricular fistula.The lesion characteristic was the blood flow from left to right,and the fistula in right ventricle.His left anterior descending and right coronary artery became stenosis,for the reason of coronary heart disease.The resistance in distal vascular bed continued to increase while the left anterior descending became stenosis.So the high diagonal branch was expansion and circuity extremely,and the right ventricular fistula was large diameter.The treatment selected intervention or surgical operation.
