【 摘 要 】

Objective: Coronary anomalies do not generate symptoms, it is incidental findings when performing a coronary angiography in a patient with ischemic heart disease or valvular heart disease. The anomalous origin of the circumflex (LCX) of the right coronary artery (RCA) is one of the common anomalies. We describe a case of CX orifice  arising from right coronary sinus in a ``shotgun`` manner with orifice of RCA and successful percutaneous coronary intervention (PCI) of lef anterior descending artery (LAD).Case Report50% ST-segment resolution at 60 minutes and relief angina) and then underwent to successful PCI.Conclusion: The ectopic origin of the CX is a well-recognized variant, which is considered the most common coronary anomaly. Although this anomaly is classified as benign and asymptomatic, a few cases of sudden death, myocardial infarction, and angina pectoris in the absence of atherosclerotic lesion have been reported. We described coronary anomaly without atherosclerotic lesion  identified in a patient with ST elevation anterior myocardial infarction who underwent successful PCI of culprit LAD. Such coronary anomalies should be considered as well in patients with STEMI undergoing PCI.
