Insights
A rare coronary artery anomaly, the ectopic origin of the left circumflex artery from the right coronary artery, was identified in a patient with myocardial infarction. Accurate diagnosis of such anomalies is crucial for patient outcomes.
Area of Science:
- Cardiology
- Anatomical Variations
Background:
- Coronary artery anomalies occur in 0.6%-1.55% of patients undergoing angiography.
- Diagnostic angiography increasingly identifies these abnormalities.
- This report details an unusual case of anomalous coronary artery origin.
Purpose of the Study:
- To report a rare case of anomalous left circumflex coronary artery origin.
- To emphasize the importance of identifying coronary artery anomalies.
Main Methods:
- Case presentation of a 45-year-old male with non-ST elevation myocardial infarction.
- Coronary angiography was performed to diagnose the anomaly.
Main Results:
- An ectopic left circumflex coronary artery originating from the proximal right coronary artery was identified.
- This specific anatomical variation is exceptionally rare.
Conclusions:
- Anomalous coronary artery origins are uncommon but can lead to significant cardiac events like myocardial ischemia and sudden death.
- Reliable identification of these anomalies is critical for effective management and therapeutic intervention planning.
Introduction:
Coronary artery anomalies are found in 0.6% to 1.55% of patients who undergo coronary angiography, and the increasing use of diagnostic coronary angiography is uncovering even more such abnormalities. We present a very unusual case of an anomalous origin of the left circumflex coronary artery (LCx) from the proximal right coronary artery (RCA).
Case Presentation:
We present a case of a 45-year-old-man with a recent history of a non ST elevation myocardial infarction. The coronary angiography reveals an ectopic left circumflex coronary artery from the right coronary artery. In this report we attempted to highlight the rarity of this coronary anatomy.
Conclusion:
Anomalous origins of the coronary artery are rare, but may cause myocardial ischemia and sudden death. Thus, their reliable identification is a matter of paramount importance possibly evaluating the effects of therapeutic intervention.

Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
