Coronary artery fistula (CAF) is a rare congenital anomaly that can be complicated by endocarditis, myocardial infarction, or coronary aneurysms. Our study summarized the clinical characteristics and surgical outcome of eight patients with CAF at department of cardiothoracic surgery, Guilin Medical University Hospital. From 2009 to 2016, eight patients (age, 8 months to 54 years were diagnosed with CAF by echocardiography, Multidetector CT or surgery. Four were female and four were male. Seven patients with isolated CAF were asymptomatic. One patient with associated anomaly (coronary artery aneurysm, aortic valve prolapse with severe aortic regurgitation) had dyspnea on exertion and palpitation. Four fistulas originated from the right and the other four originated from the left coronary artery. Drainage was to the right ventricle (four), right atrium (three) and left ventricle (one). All patients had surgical ligation. In the symptomatic patient, in addition to excision of aneurysm, aortic valve replacement was performed. There was no operative or late death. Follow-up evaluation (range, 2-7 years; mean, 4.1 years) showed no evidence of recurrent or residual CAF. Surgical management of CAF is a safe and effective treatment resulting in 100% survival and closure rate.
