Non atherosclerotic left main coronary artery ostial lesion

This report addresses a case of ischemic heart disease whose initial clinical expression was Takayasu s Arteritis (TA). Hospitalized for coronary artery bypass graft surgery (CABG) due to stable angina and isolated left main coronary artery lesion, the patient presented vascular anomalies during the physical examination that suggested a diagnosis of TA. This report prompts reflection on seeking etiologies other than atherosclerotic coronary artery disease, especially in young people or among those with few risk factors. Although infrequent compared to other vascular lesions found in this disease, involvement of the coronary artery in TA results in high morbidity and mortality rates.
