Abstract:
A 69-year-old female with left atrial tumor was refered to our hospital for surgical treatment. The tumor was attached to the interatrial septum and resected completely. Histopathological analysis confirmed a myxoma with ossification(mature bone). These findings may support the hypothesis that the undifferentiated mesenchymal cells are the origin of cardiac myxoma.
