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.
Abstract:
Coronary artery fistulae can present late in adult life. We describe the case of a 71-year-old woman who developed a right coronary fistula, which was managed by percutaneous transbrachial coil embolization. Complete closure of the fistula was confirmed by follow-up angiography at 10 months.
