Abstract:
Primary cardiac myxofibrosarcoma is an extremely rare malignant tumor of the heart, which can be difficult to diagnose. We report such a case, which recurred 7 months after the initial heart surgery. A 63-year-old woman with progressive dyspnea was seen by a physician. A transthoracic echocardiography revealed a large mobile mass in the left atrium, causing severe mitral stenosis. The patient was referred to our hospital for an operation. The tumor, which arose from the anterior mitral annulus, was resected, and mitral and tricuspid annuloplasty were performed. The histopathological diagnosis was myxoma. The postoperative course was uneventful. Seven months later, the patient reported suffering from dyspnea and leg edema. The echocardiography showed multiple recurrences of tumor in the left atrium. A second operation was performed to reduce the mass volume as a palliative treatment because some large fragile tumors occupied the left atrium. The patient died 5 months after the second operation due to metastasis. The final diagnosis by histopathology was myxofibrosarcoma.
