Summary
A rare intrapericardial bronchogenic cyst caused left main coronary artery stenosis in a young woman, leading to exertional syncope. Surgical resection and angioplasty resolved symptoms, highlighting an unusual complication of this congenital anomaly.
Area of Science:
- Cardiology
- Thoracic Surgery
- Medical Imaging
Background:
- A 32-year-old woman presented with syncope after exertion, with no prior cardiovascular history.
- Initial investigations included transesophageal echocardiography to rule out aortic dissection.
Observation:
- An incidental finding during echocardiography revealed a 5x6 cm cystic mass posterior to the aortic root and main pulmonary artery.
- Exercise electrocardiogram (ECG) showed significant ST-segment depression and anginal symptoms, suggesting compromised coronary artery flow during exertion.
Findings:
- Coronary angiography identified an 80% stenosis at the origin of the left main coronary artery.
- Surgical exploration confirmed an intrapericardial bronchogenic cyst compressing the left main coronary artery ostium.
Implications:
- This case highlights a previously unreported complication of bronchogenic cysts causing coronary artery stenosis.
- Complete cyst resection and coronary ostial angioplasty successfully restored coronary artery patency and relieved symptoms.
- Early diagnosis and intervention are crucial for managing this rare but potentially serious condition.
