Summary
A rare single coronary artery anomaly from the left sinus of Valsalva, coupled with severe atherosclerosis, caused unstable angina. The circumflex artery unusually extended to supply the right coronary artery territory.
Area of Science:
- Cardiology
- Anatomical Variations
- Vascular Biology
Background:
- Coronary artery anomalies are rare congenital conditions.
- Unstable angina is a critical manifestation of coronary artery disease.
- Atherosclerosis significantly impacts coronary artery function.
Observation:
- A patient presented with symptoms of unstable angina.
- A rare single coronary artery anomaly was identified, originating from the left sinus of Valsalva.
- Extensive atherosclerosis was present within the anomalous coronary artery.
Findings:
- The single coronary artery exhibited severe atherosclerotic disease.
- The distal circumflex artery followed the anatomical course of the right coronary artery.
- This anatomical variation and disease burden likely precipitated the unstable angina.
Implications:
- Highlights the importance of recognizing rare coronary anomalies in clinical practice.
- Underscores the potential for severe atherosclerosis in anomalous coronary arteries.
- May influence diagnostic and therapeutic strategies for patients with coronary artery anomalies and ischemic heart disease.
