Giant coronary artery fistula complicated with coronary artery aneurysm and acute myocardial infarction: a case report.

BACKGROUND: 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. CASE PRESENTATION: 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. CONCLUSION: 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.
