Asymptomatic single coronary artery in patient with severe peripheric artery disease

Area of Science:

• Cardiovascular Medicine
• Anatomical Variations
• Vascular Biology

Background:

• Congenital coronary artery anomalies are rare but can have significant clinical implications.
• Single coronary artery (SCA) is a rare anomaly, with various anatomical presentations.
• Peripheral arterial disease (PAD) significantly impacts patient morbidity and mortality.

Observation:

• A 70-year-old patient presented with severe and progressive peripheral arterial disease.
• Diagnostic imaging revealed a rare anatomical variation: a single coronary artery.
• In this specific case, the right coronary artery originated anomalously from the distal left circumflex artery.

Findings:

• The patient had a solitary coronary artery without other coexisting cardiovascular malformations.
• The anatomical configuration involved the right coronary artery arising from the left circumflex artery.
• Despite the coronary anomaly, the primary clinical concern was severe peripheral arterial disease.

Implications:

• This case highlights the importance of recognizing rare coronary artery anomalies, even in the absence of typical ischemic symptoms.
• The association between this specific SCA variant and severe PAD warrants further investigation.
• Understanding such anatomical variations is crucial for accurate diagnosis and tailored patient management in cardiovascular medicine.
