Summary
Coronary arteriovenous fistulae are rare congenital heart defects. This case details a rare instance involving multiple coronary vessels draining into the coronary sinus, with the patient currently asymptomatic.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Vascular Malformations
Background:
- Coronary arteriovenous fistula (CAVF) is a rare congenital cardiac malformation.
- Most reported CAVF cases involve a single coronary vessel.
Observation:
- This report documents the second known case of CAVF involving multiple coronary vessels.
- The fistula involved both the right and circumflex coronary arteries.
- The abnormal vessels drained directly into the coronary sinus.
Findings:
- The patient presented with a rare form of coronary arteriovenous fistula.
- The fistula involved the right and circumflex coronary arteries draining into the coronary sinus.
- No significant ischemic symptoms or hemodynamic impairment were observed at the time of reporting.
Implications:
- This case expands the understanding of rare coronary arteriovenous fistula presentations.
- Highlights the importance of considering multiple vessel involvement in coronary arteriovenous fistulae.
- Suggests that some complex CAVFs may be hemodynamically well-tolerated initially, warranting medical follow-up.
