Anomalous Double Right Coronary Artery Presenting as Inferior Wall ST-elevation Myocardial Infarction: A Rare...

Area of Science:

• Cardiology
• Congenital Heart Disease
• Vascular Anatomy

Background:

• Congenital anomalous origin of coronary arteries (CAOC) is an uncommon condition, affecting 0.2%-2% of patients undergoing coronary angiography (CAG).
• While often benign, CAOC can lead to severe symptoms like myocardial ischemia and sudden cardiac death.
• Prognosis is influenced by the anomalous artery's origin, its course within the heart muscle, and its relationship with adjacent great vessels and cardiac structures.

Observation:

• A 52-year-old male presented with a congenital anomalous origin of coronary arteries.
• Diagnostic coronary angiography revealed a double right coronary artery.
• The anomalous origin was identified as arising from a noncoronary aortic cusp.

Findings:

• The identified anomaly, a double right coronary artery originating from a noncoronary aortic cusp, represents a novel finding in the medical literature.
• This specific anatomical variation has not been previously reported.
• Computed tomography coronary angiography (CT-CAG) aids in the increased detection and reporting of such rare coronary anomalies.

Implications:

• This case highlights the importance of recognizing rare coronary artery anomalies for accurate diagnosis and risk stratification.
• Enhanced awareness and advanced imaging techniques like CT-CAG are crucial for identifying and studying these variations.
• Further investigation into the clinical significance and management of this specific anomaly is warranted.
