Coronary artery fistulas are anomalous terminations of the coronary arteries. Most often, these fistulas are incidentally identified in the adult and pediatric populations. Many patients are asymptomatic; however, an awareness of these fistulas is important because they have been associated with various clinical features, including chest pain or heart failure in young patients. Correct diagnosis of coronary artery fistulas is important, and early surgical correction is indicated because of the high prevalence of late symptoms and complications. Traditionally, conventional angiography has been used for the diagnosis of coronary anomalies. With more frequent use of 64-row multi-detector computed tomography (CT) in chest and cardiac imaging, the number of incidentally found coronary artery fistulas has been increasing. CT angiography and conventional angiography can have additive value in diagnosis of this cardiac anomaly. In every CT study of the heart, special attention should be paid to the courses and terminations of the coronary arteries to detect these potentially fatal anomalies.
冠状动脉瘘是冠状动脉的异常终末。这些瘘管最常于成人和儿童人群中被偶然发现。许多患者无症状；然而，了解这些瘘管很重要，因为它们与多种临床特征相关，包括年轻患者的胸痛或心力衰竭。正确诊断冠状动脉瘘很重要，鉴于晚期症状和并发症的高发生率，早期手术矫正很有必要。传统上，常规血管造影术一直用于诊断冠状动脉异常。随着64排多层螺旋计算机断层扫描（CT）在胸部和心脏成像中的更频繁使用，偶然发现的冠状动脉瘘数量一直在增加。CT血管造影和常规血管造影在诊断这种心脏异常方面可能具有附加价值。在每一次心脏CT检查中，都应特别关注冠状动脉的走行和终末情况，以检测这些潜在致命的异常。
