Medium-sized LCX aneurysm | Coronary angiogram: proximal RCA aneurysm with a diameter of 8.6 mm. Multiple stenotic lesions in the RCA and LCX | Coronary angiogram: aneurysmal left main artery ( mm), ostial LAD was subtotally occluded, LCX 90% eccentric ostial stenosis. Dominant RCA with 70-80% ostial stenosis |
