Among the congenital anomalies of the coronary arteries, absent left circumflex artery (LCX) defect is extremely rare. Only a few cases have been reported in the literature. We report a case of a 48-year-old female who presented with a 4-month history of exertional chest pain with positive stress (treadmill) test. Conventional coronary angiogram showed a normal left anterior descending, absent LCX and a super-dominant right coronary artery (RCA) with prominent branches. Aortography also failed to show a separate ostium for the left circumflex artery. Multi-detector computed tomographic coronary angiography was performed to confirm the diagnosis of congenital absence of the LCX. It is a benign incidental finding, however some patients present with angina-like symptoms often resulting in detection of this rare anatomy on coronary angiography. Precise morphological and functional evaluation of the anomalous coronary artery is important for selecting the best treatment modality and better prognosis.
