Insights

Late-presenting coronary artery fistulae can occur in adults. This case study shows successful percutaneous transbrachial coil embolization for a right coronary fistula in a 71-year-old woman.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Medicine

Background:

  • Coronary artery fistulae (CAF) are uncommon congenital or acquired abnormalities.
  • While often asymptomatic, CAFs can manifest in adulthood with symptoms like angina or heart failure.

Observation:

  • A 71-year-old woman presented with symptoms attributed to a right coronary artery fistula.
  • The fistula represented a late-onset manifestation of coronary artery anomaly.

Findings:

  • Percutaneous transbrachial coil embolization was successfully employed to manage the right coronary artery fistula.
  • Angiographic follow-up at 10 months confirmed complete and durable closure of the fistula.

Implications:

  • Percutaneous embolization is a viable and effective treatment option for adult-onset coronary artery fistulae.
  • This case highlights the importance of considering coronary fistulae in the differential diagnosis of adult cardiac conditions and demonstrates a minimally invasive therapeutic approach.
