Angiographic recognition and percutaneous intervention of an occluded anomalous circumflex coronary artery causing acute myocardial infarction: a case report


Coronary arteries with anomalous origin are unusual but can be responsible for myocardial infarction. Acute occlusion of an anomalous coronary artery is not only easily missed on angiography but also technically challenging for percutaneous intervention. In this report, we present our experience in a patient with an anomalous circumflex being the culprit vessel in acute myocardial infarction. We report a case of a 74-year-old male patient presented with sudden chest pain. The diagnosis of occluded anomalous circumflex coronary artery was made by invasive coronary angiography shortly after admission. The patient was stented with a 2.5 x 18mm bare metal stent and was discharged with intensive medical treatment and regular follow-up. Interventional cardiologists should keep in mind there are several anomalous origin, the most frequent anomaly being a circumflex artery with origin from the right coronary artery or the right sinus of Valsalva.
