Abstract

Left atrial myxoma is a common primary tumor which frequently presents systemic embolizations. Embolization in various systemic organs is often the first and sometimes the only symptom in patient with cardiac myxoma. However, coronary embolization from the left atrial myxoma is very rare clinical presentation. We experienced 57-year-old woman with a left atrial myxoma combined with inferior myocardial infarction who had no stenotic lesion in coronary angiography. The ergonovine spasm test was negative. In the interleukin-6 immunohistochemical staining, the extracellular matrix of myxoma stained abundantly with pink color. It can be considered as inferior myocardial infarction due to embolization from the myxoma, which is associated with interleukin-6. So, we report this case with review of literature for the first time in Korea.
