Transradial Percutaneous Coronary Intervention in a Patient with a Rare Coronary Anomaly: Twin Circumflex Arteries

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Anatomical Variations

Background:

• Coronary artery anomalies are uncommon congenital conditions affecting coronary artery anatomy.
• Percutaneous coronary intervention (PCI) is a standard treatment for coronary artery stenosis.
• Anatomical variations can pose challenges during interventional procedures.

Observation:

• A 65-year-old male presented with exertional chest pain.
• Diagnostic workup revealed significant stenosis in an anomalous right-sided circumflex artery.
• The anomaly involved twin circumflex arteries originating from the left main coronary artery and the right coronary artery ostium.

Findings:

• Successful percutaneous coronary intervention (PCI) was performed via transradial access.
• The procedure addressed critical stenosis within the anomalous right-sided circumflex artery.
• This case highlights the successful management of a rare coronary artery anomaly.

Implications:

• Demonstrates the feasibility of PCI in managing stenotic lesions on complex coronary artery anomalies.
• Emphasizes the importance of recognizing and addressing anatomical variations during interventional cardiology.
• Transradial access can be a viable approach for complex coronary interventions involving anomalous vessels.
