Insights
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.
Abstract:
Coronary arteriovenous fistula is an uncommon, although not rare, congenital cardiac malformation, especially in the adult. Most such reported such cases have involved but a single coronary vessel. This report documents the second case of coronary arteriovenous fistulae involving the right and circumflex coronary vessels draining into the coronary sinus. At the present time the patient is free of definite ischemic symptoms or obvious impairment of hemodynamic function and is being followed-up medically.
