Summary
This case report details an unusual finding of multiple coronary arteriovenous fistulas. These abnormal connections originated from both coronary arteries and drained into the pulmonary trunk.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Medical Case Reports
Background:
- Coronary arteriovenous fistulas (CAFs) are rare congenital or acquired abnormalities.
- Most CAFs involve a single coronary artery draining into a cardiac chamber or systemic vein.
- Drainage into the pulmonary trunk is an exceptionally uncommon presentation.
Observation:
- A 62-year-old patient presented with an exceptionally rare presentation of multiple coronary arteriovenous fistulas.
- These fistulas originated from both the left and right coronary arteries.
- The abnormal vessels drained directly into the pulmonary trunk.
Findings:
- The case demonstrates a complex network of arteriovenous fistulas involving both major coronary arteries.
- The pulmonary trunk served as the unusual drainage site for these fistulas.
- This anatomical variation represents a significant deviation from typical coronary circulation.
Implications:
- This case expands the spectrum of known coronary arteriovenous fistula presentations.
- Understanding such anomalies is crucial for accurate diagnosis and management of complex congenital heart disease.
- Further research into the embryological origins and clinical significance of multiple CAFs draining into the pulmonary trunk is warranted.
