Insights
Anomalous aortic origin of the left main coronary artery (AAOLCA) is a rare condition causing heart problems. Transconal unroofing offers a safe and effective surgical solution for this anomaly.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Anomalous aortic origin of the left main coronary artery (AAOLCA) is a rare congenital anomaly.
- It can lead to myocardial ischemia and sudden cardiac death.
- Traditional surgical management is complex.
Background:
Anomalous aortic origin of the left main coronary artery (AAOLCA) with a transseptal course is an exceptionally rare anomaly associated with myocardial ischemia and sudden cardiac death. Surgical management has traditionally required complex repair.
Case Summary:
A 41-year-old man presented with acute chest pain and ST-segment elevations. Angiography revealed no obstructive coronary disease but identified an AAOLCA from the right coronary sinus with a transseptal course. Physiologic testing demonstrated ischemia under dobutamine stress. The patient underwent successful transconal unroofing and right ventricular outflow tract reconstruction through replication of a novel transconal approach.
Discussion:
This case highlights the importance of multimodality imaging and physiologic assessment in diagnosing high-risk AAOLCA variants. Careful unroofing and patch reconstruction can relieve compression while avoiding conduction injury or obstruction of the right ventricular outflow tract.
Take-Home Message:
Transconal unroofing for AAOLCA with extended transseptal course is safe, reproducible, and provides favorable early outcomes.
