Left main coronary artery aneurysm.

Left main coronary aneurysm is extremely uncommon and its precise pathogenesis remains poorly understood. They are associated with serious complications and treatment is still the subject of disagreement. The authors present the case of a 42-year-old man admitted for a coronary syndrome, whose coronary angiogram revealed a large left main coronary aneurysm. The echocardiogram and multi-row detector CT angiography confirmed the abnormalities observed. No positive findings resulted from etiological evaluation. We decided to maintain the patient under oral anticoagulation and he remains clinically stable after two years of follow-up.
