Congenital absence of the left circumflex artery associated with inferior myocardial infarction.
Congenital absence of the left circumflex artery is a rare anomaly of the coronary arteries. A 52-year-old man who developed acute inferior myocardial infarction underwent coronary angiography which revealed the absence of the left circumflex artery and that the surrounding structures were supplied by the infarct-related super-dominant right coronary artery. Two stents were implanted into the right coronary artery and one stent into the mid portion of the left anterior descending artery. Follow-up coronary angiography at 67 months showed no detectable restenosis, and 64-slice multidetector computed tomography confirmed the absence of the left circumflex artery. The circumflex artery as a terminal extension of a culprit right coronary artery has not been previously reported.
