Insights
A rare single coronary artery anomaly presented as a 60-year-old man
Area of Science:
- Cardiovascular Medicine
- Radiology
- Anatomy
Background:
- Acute ST-elevated myocardial infarction (STEMI) necessitates prompt diagnosis and intervention.
- Coronary artery anomalies are uncommon but can lead to significant cardiovascular events.
- The right coronary artery (RCA) ostium was undetectable in this patient.
Abstract:
A 60 year-old man presenting with chest pain was diagnosed with acute ST-elevated myocardial infarction. An emergency coronary angiography showed distal left circumflex artery (LCX) occlusion. The ostium of the right coronary artery (RCA) was not detectable. Following primary percutaneous coronary intervention in the occluded LCX, we confirmed that RCA region was fed from both LAD and LCX. Coronary computed tomography showed similar findings. This single coronary artery anomaly is extremely rare and cannot be categorized according to the established classification system.
