“…In patients with CAD, if LCx cannot be visualized during CAG, either an atherosclerotic ostial occlusion or congenital absence/agenesis should be suspected. 37,47 The LCx is known to arise anomalously from the RCA, separately from the left sinus of Valsalva, or very rarely from the pulmonary artery or non-coronary sinus. 22,48,49 The LCx and RCA normally run through the AV groove, forming a loop.…”

Congenital absence of the left circumflex artery (CALCx) or an anomalous origin of the left circumflex artery from the right coronary artery is a unique anomaly in the literature that has been incidentally diagnosed with coronary angiography. CALCx is characterized by an angiographical absence of the left circumflex artery, with a super-dominant right coronary artery that provides the postero-lateral wall of the left ventricle. We present a review of the literature of a total of 52 CALCx cases reported so far including our case. In our study, the average age of patients was 52.83 years (median – 55 years; standard deviation – 13.05 years; range 12–76 years) with a male to female ratio of 1.93:1. The chronic coronary syndrome was the most common clinical presentation followed by the acute coronary syndrome. In 45.5% of cases, the associated coronary artery disease was documented. A comprehensive anatomical and functional assessment is required for the appropriate management strategy.

“…Congenital absence of the left circumflex coronary artery (LCx) is a very rare vascular anomaly (3,4). We report a case of inferior acute myocardial infarction (AMI) in a 52-year-old man in whom the absence of the LCx arose as an extension of the distal culprit superdominant right coronary artery (RCA).…”

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.

“…[ 2 ] LCA as an extension of RCA is a very rare anomaly, being reported in only few cases in the literature. [ 3 4 ] Coronary artery anomalies can be divided into benign and malignant forms. Benign abnormalities often remain asymptomatic because they are hemodynamically insignificant.…”
