Left main coronary trunk connecting into right atrium with an aneurysmal coronary artery fistula
Insights
Congenital coronary artery fistula (CAF) is a rare vascular anomaly. Multi-slice CT angiography is recommended for diagnosing aneurysmal-CAF between the left main trunk and right atrium.
Area of Science:
- Cardiovascular Medicine
- Medical Imaging
- Congenital Heart Disease
Background:
- Congenital coronary artery fistula (CAF) represents a rare vascular malformation.
- CAFs create abnormal direct connections between coronary arteries and cardiac chambers or major vessels.
Observation:
- A case presented with an aneurysmal-CAF connecting the left main coronary artery to the right atrium.
- Initial diagnosis via transthoracic echocardiography suggested Kawasaki disease.
Findings:
- Coronary angiography and multi-slice CT angiography confirmed the diagnosis of aneurysmal-CAF.
- Multi-slice CT angiography proved highly effective for detailed characterization.
Implications:
- This case highlights the importance of considering rare congenital anomalies in differential diagnoses.
- Multi-slice CT angiography emerges as a preferred imaging modality for complex CAFs.
- Accurate diagnosis and characterization are crucial for appropriate patient management.
Abstract:
Congenital coronary artery fistula (CAF) is an infrequent vascular anomaly that establishes a direct link between an epicardial coronary artery and a cardiac chamber, major vessels, or other vascular structures. In this case there was an aneurysmal-CAF between a left main trunk and the right atrium, which was initially diagnosed as a Kawasaki disease by transthoracic echocardiography and subsequently confirmed by coronary angiography and multi-slice CT angiography. A multi-slice CT angiography might well become the modality of choice for the characterization of these rare congenital anomalies.
