Coronary artery fistulas are abnormal connections between the coronary arteries and the heart or other surrounding vascular structures. Although they are usually congenital, they can also occur iatrogenically or due to trauma. They are usually asymptomatic, but they can cause serious and even fatal complications. These complications include myocardial infarction, embolism, thrombosis, arrhythmia, and rupture. In a 54-year-old woman admitted to the emergency department with an acute inferior myocardial infarction, a giant coronary-pulmonary artery fistula was detected on angiography. The fistula could not be closed percutaneously, and computed tomography angiography (CTA) revealed extensive aneurysms and diffuse calcifications. Large fistulas should be closed due to the risk of rupture. Small fistulas should be detected by CTA, and radiologists should be familiar with the imaging features.
冠状动脉瘘是冠状动脉与心脏或其他周围血管结构之间的异常连接。虽然它们通常是先天性的，但也可医源性发生或因外伤所致。它们通常无症状，但可引起严重甚至致命的并发症。这些并发症包括心肌梗死、栓塞、血栓形成、心律失常和破裂。在一名因急性下壁心肌梗死入住急诊科的54岁女性患者中，血管造影检查发现巨大冠状动脉-肺动脉瘘。该瘘无法经皮闭合，计算机断层血管造影（CTA）显示广泛的动脉瘤和弥漫性钙化。由于存在破裂风险，大的瘘应予以闭合。小的瘘应由CTA检测，放射科医生应熟悉其影像学特征。
