Percutaneous coronary intervention for a single coronary artery arising from the right sinus of Valsalva

Area of Science:

• Cardiology
• Anatomical Variations
• Interventional Cardiology

Background:

• Myocardial infarction (MI) can arise from complex coronary artery anatomy.
• Congenital coronary artery anomalies are rare but clinically significant.
• Accurate diagnosis of coronary artery anomalies is crucial for effective treatment.

Observation:

• A 67-year-old woman presented with acute lateral myocardial infarction.
• Coronary angiography revealed a single coronary artery originating from the right sinus of Valsalva.
• The left anterior descending and left circumflex arteries arose anomalously from the right coronary artery.

Findings:

• A critical 99% stenosis with a filling defect was identified in the mid-left circumflex artery.
• This represented an extremely rare coronary artery anomaly.
• Percutaneous coronary intervention (PCI) was performed to address the stenosis.

Implications:

• Successful PCI in the setting of a rare coronary anomaly demonstrates treatment feasibility.
• This case highlights the importance of recognizing and managing complex coronary anatomy.
• Interventional strategies can effectively treat acute coronary syndromes caused by anomalous coronary arteries.
