Coronary artery fistula (CAF) is an abnormal connection between a coronary artery and either a cardiac chamber or the great vessels. Although most patients are asymptomatic, potential complications such as heart failure, angina pectoris or acute myocardial infarction can be fatal. We present here a 62-year-old man diagnosed with giant coronary artery fistula complicated with gross coronary artery aneurysm and acute myocardial infarction. He underwent intravenous thrombolysis treatment at a local hospital, coronary angiography at a regional hospital and complex surgery at a national centre for cardiovascular disease. The patient had no major adverse cardiac events during the 3-year follow-up. Early diagnosis of CAF patients and an appropriate treatment plan are the key factors for avoiding serious complications. Because of the rare incidence of this disease, it is necessary to discover and discuss management strategies, including medical management, percutaneous interventions or surgical treatment, for a successful outcome.

巨大冠状动脉瘘并发冠状动脉瘤和急性心肌梗死一例报告

冠状动脉瘘（CAF）是冠状动脉与心腔或大血管之间的异常连接。尽管大多数患者无症状，但潜在的并发症如心力衰竭，心绞痛或急性心肌梗塞可能是致命的。我们在这里介绍了一名62岁的男子，他被诊断出患有巨大的冠状动脉瘘并伴有冠状动脉总动脉瘤和急性心肌梗塞。他在当地一家医院接受了静脉溶栓治疗，在一家地方医院进行了冠状动脉造影，并在国家心血管疾病中心接受了复杂的手术。在3年的随访期间，该患者无重大心脏不良事件。CAF患者的早期诊断和适当的治疗计划是避免严重并发症的关键因素。
