Coronary artery fistula (CAF) is a rare cardiac anomaly. Here, we diagnosed a right coronary artery-right atrium fistula with giant coronary artery aneurysm (CAA) via fetal echocardiography at 35 weeks' gestation. An urgent caesarean delivery was performed at 36 weeks' gestation because CAA caused mitral obstruction, and fetal atrial flutter was present. Following delivery, we performed aneurysm ligation because the new-born developed atrial tachycardia. The intraoperative findings confirmed the sonographic findings. To the best of our knowledge, prenatal ultrasound diagnosis of CAF and giant CAA has not been reported in the literature. We focus on the ultrasonic characteristics and differential diagnosis in this literature.
冠状动脉瘘（CAF）是一种罕见的心脏畸形。在此，我们通过胎儿超声心动图在 35 孕周时诊断出右冠状动脉-右心房瘘伴巨大冠状动脉瘤（CAA）。由于 CAA 导致二尖瓣梗阻，并出现胎儿房性心动过速，因此在 36 孕周时行紧急剖宫产术。分娩后，我们进行了动脉瘤结扎术，因为新生儿出现了房性心动过速。术中发现证实了超声检查的结果。据我们所知，产前超声诊断 CAF 和巨大 CAA 在文献中尚未报道。我们在此文献中重点介绍了超声特征和鉴别诊断。
