Coronary artery fistula is an abnormal direct connection between the coronary artery and any of the four chambers of the heart or great vessels. A fistula from the left circumflex coronary artery to the coronary sinus is a relatively rare situation. We report a case of 12-month-old infant with coronary artery fistula from the left circumflex coronary artery to the coronary sinus that was identified incidentally. The N-terminal pro-brain natriuretic peptide level was elevated. Additionally, the proximal segment of the left circumflex coronary artery was dilated. On the basis of these findings, percutaneous closure of the fistula was performed with a vascular plug. This procedure achieved no residual flow and good hemodynamics were observed during follow-up.
冠状动脉瘘是指冠状动脉与心脏的四个腔室或大血管之间的异常直接连接。左回旋支冠状动脉至冠状窦的瘘管是一种相对罕见的情况。我们报告了一例 12 个月大的婴儿，其左回旋支冠状动脉至冠状窦的冠状动脉瘘是偶然发现的。N 末端脑利钠肽前体水平升高。此外，左回旋支冠状动脉的近端节段扩张。基于这些发现，使用血管塞进行了瘘管的经皮封堵。该操作实现了无残余血流，在随访过程中观察到了良好的血液动力学。
