Insights
Coronary artery fistulae, a rare heart defect, were successfully treated in one patient using pulmonary artery transection. This case highlights a unique surgical approach for complex coronary artery abnormalities near the left main trunk.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Medical Case Reports
Background:
- Coronary artery fistula is a rare congenital or acquired abnormality.
- Surgical treatment for coronary artery fistulae lacks standardization, requiring individualized approaches.
- Fistulae adjacent to critical structures like the left main trunk pose significant surgical challenges.
Abstract:
Coronary artery fistula is a rare abnormality in the communication between a coronary artery and any of the cardiac chambers or major vessels. At present, there is no standard surgical treatment and the most appropriate method is selected on a case-by-case basis. We report one case of coronary artery fistulae in which pulmonary artery transection was required around the left main trunk (LMT). A 62-year-old man who had coronary artery fistulae with an aneurysm which increased from 12 mm to 16 mm in a two-year span. The fistula was located adjacent to the LMT. A complete aneurysm excision under cardiopulmonary bypass was performed, which required pulmonary artery transection. No postoperative complications occurred. Postoperative coronary computed tomography scan showed intact coronary arteries and complete aneurysm removal.
