Insights
A rare coronary artery anomaly, mimicking atherosclerotic coronary artery disease, caused chest pain and dyspnea. Early diagnosis is crucial as symptoms are indistinguishable from typical heart disease.
Area of Science:
- Cardiology
- Medical Imaging
- Anatomical Variations
Background:
- A 40-year-old female experienced exertional chest pain and dyspnea.
- Symptoms suggested potential atherosclerotic coronary artery disease.
Purpose of the Study:
- To report a rare coronary artery anomaly.
- To highlight diagnostic challenges in differentiating from coronary artery disease.
Main Methods:
- Electrocardiography (ECG) revealed ST-depression.
- Exercise treadmill testing (ETT) showed further ST-depression.
- Coronary angiography identified a single left coronary artery with an anomalous origin of the right coronary artery.
Main Results:
- The patient presented with symptoms consistent with myocardial ischemia.
- Diagnostic tests indicated significant ST-segment changes.
- Coronary angiography revealed a rare coronary artery anomaly without obstructive atherosclerotic lesions.
Conclusions:
- A single left coronary artery with anomalous right coronary artery origin is a rare condition.
- Symptoms of this anomaly can be indistinguishable from atherosclerotic coronary artery disease.
- Accurate diagnosis of this anomaly is vital for appropriate patient management.
Background:
A 40-years-old female presented with intermittent chest pain and dyspnea on exertion.
Case Presentation:
Electrocardiography showed sinus rhythm with ST-depression in inferior and lateral leads. Subsequent exercise treadmill testing revealed significant ST-depression in V4-V5 and V6 leads. Coronary angiography later showed a single left coronary artery with right coronary artery arising from left circumflex artery, a rare anomaly of coronary arteries. No atheromatous lesion was seen during angiography.
Conclusion:
The dignosis of this anomaly is importsnt because the symptoms cannot be differentiated from atherosclerotic coronary artery disease.

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...

During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...
