A Rare Anomalous Origin of the Right Coronary Artery From Mid-Left Anterior Descending Artery
Key result
CTA is strongly recommended to evaluate suspected coronary anomalies such as RCA originating from mid-LAD.
- n=1
Why the study?
Coronary artery anomalies are a leading cause of sudden cardiac death in young athletes, with limited evidence guiding management of symptomatic cases.
Population
A patient with a single coronary artery anomaly with RCA originating from mid-LAD
Comparison
Computed tomography coronary angiography and stress imaging for diagnosis
Design

Implication
Enables precise mapping of anomalous vessels to inform management; extends known spectrum of coronary artery origins.
Key Points
- To describe the diagnostic challenges and clinical findings associated with a rare single coronary artery anomaly where the right coronary artery originates from the mid-left anterior descending artery.
- Evaluated a symptomatic individual using invasive coronary angiography, stress imaging, and computed tomography coronary angiography (N=1).
- Stress imaging demonstrated no evidence of inducible myocardial ischemia.
- Invasive angiography initially suggested an ostial chronic total occlusion, but computed tomography coronary angiography identified an antegrade right coronary artery with a malignant interarterial course originating from the mid-left anterior descending artery.

Cite This Study
Elbasha et al. (2026) conducted a case report in Single coronary artery anomaly (n=1). Computed tomography coronary angiography was evaluated on Diagnosis of coronary anomaly. Computed tomography coronary angiography successfully resolved diagnostic uncertainty in a rare case of an anomalous right coronary artery originating from the mid-left anterior descending artery.
