Abstract
|
Introduction:
malies. They occur in 0.1–0.8% of patients undergoing coronary arteriography. The circumflex coronary arteriovenous fistulae (CAF) associated with aneurysmal dilatation and drainage into coronary sinus (CS) are even less common. We present a case of a 56-year-old male with an acute coronary syndrome who was found to have a tortuous and aneurysmal circumflex coronary artery terminating into the CS.
Case Report: A previously healthy 56-year-old male developed acute retrosternal chest pain while skiing. Physical examination revealed a grade II/VI continuous murmur at the left lower sternal border, but was otherwise unremarkable. Laboratory investigations revealed an elevated troponin and ST depression in the inferior leads on his electrocardiography. Coronary angiography showed a diffusely aneurysmal circumflex artery with a fistula to the CS. The patient underwent successful surgical ligation of the fistula. Conclusion: Our patient presented with an acute coronary syndrome caused by an uncommon form of coronary artery fistula. Conventional coronary angiography failed to fully define the anatomy of the fistula (origin, pathway, and outflow). Multidetector computed tomography was complementary to demonstrate the complex anatomy of the fistula. The fistula was surgically ligated and he remains well. | |
