Percutaneous Coronary Intervention in an Extremely Rare Case of Double Circumflex Coronary Arteries With Acute Myocardial Infarction.

The anomalous origin of the left circumflex (Cx) artery (LCX) from the right coronary sinus or the right coronary artery (RCA) has been reported as one of the most common congenital coronary anomalies. However, the occurrence of double or twin Cx coronary arteries has been sparsely reported in the literature. We describe a rare case of a middle-aged male with acute myocardial infarction (MI) who had double Cx coronary arteries, one arising from the RCA and the other from the left main coronary artery. He underwent successful angioplasty with the stenting of the culprit right Cx artery (RCX).
