CT coronary angiography shows:
- Right dominant coronary circulation
- Anomalous origin of left circumflex (LCX) artery is seen from right coronary sinus with common ostium for both LCX and RCA. LCX courses postero-inferior to the aortic root to reenter anterior atrioventricular groove.
- Left main coronary artery (LMCA) continues as left anterior descending artery (LAD).
- Few eccentric mixed plaques are noted in proximal LAD causing 20-25% stenosis.
- No stenosis in rest of the coronary arteries.
- Atherosclerotic wall thickening and calcifications are noted in aortic root.
Case Discussion
Congenital coronary artery anomalies can involve their origin, course and termination.
