Successful Percutaneous Coronary Intervention of a Stenotic Aberrant Circumflex Artery: A Rare Cause of Acute Coronary Syndrome

 Successful Percutaneous Coronary Intervention of a Stenotic Aberrant Circumflex Artery: A Rare Cause of Acute Coronary Syndrome

Most coronary artery origin abnormalities are incidentally determined during coronary angiography. However, some cases of coronary artery abnormalities are related to severe life-threatening events such as myocardial ischemia, arrhythmia and acute myocardial infarction. A 55-years-old male was hospitalized due to acute coronary syndrome. Coronary angiography reveal that aberrant circumflex coronary artery (Cx) originated from right aortic sinus and with proximal and distal Cx severe stenosis. Coronary intervention was successfully carried out on a severe stenosis at the proximal and distal Cx artery. Determination of the anomalous origin of the coronary artery and the cardiovascular system is of great clinical importance due to its severe life-threatening complications. Cardiologists should be aware of the possibility aberrant coronaries may be cause of acute coronary syndrome.
