Her electrocardiogram was consistent with diffuse ST segment depression on the pericardial leads. The patient was referred for coronary angiography, which revealed non-obstructive coronary atherosclerosis and a giant 26x21 mm coronary aneurysm originating from the distal left main system (Fig. A and B, Videos 1 and 2**). The right coronary artery was normal, but had extensive tortuosity. Contrast-enhanced computed tomography (CT) was performed to further define the anatomy and it confirmed the size and origin of the giant left main coronary artery (LMCA) aneurysm (Fig. C and Fig. D). After consultation, the institutional heart team decided that the huge size and proximal localization of the aneurysm precluded percutaneous options, including coil embolization and graft stenting.eninfo:eu-repo/semantics/openAccessLMCA AneurysmsLeft Main Coronary ArteryOther43441441410.5543/tkda.2015.84890N/AQ3
