title: Surgical treatment of recurrent primary malignant tumor of the left atrium.
abstract: A young woman presented with a tumor in the left atrium resembling a left atrial myxoma. After simple excision of the tumor the diagnosis of primary malignant fibrous histiocytoma of the heart was made. A course of radiation therapy was given. Four subsequent recurrences were treated by cardiotomy and resection of the left atrial wall. At the third, fourth, and fifth operations fulguration of the left atrial wall was performed. Subsequent chemotherapy failed to control the tumor. The patient was admitted 6 weeks after the last resection and died. Postmortem examination revealed a large recurrent tumor obstructing the left atrium with no metastases. The clinical course, cardiac catherization data, and postmortem examination are presented. Palliation was achieved by repeated resection of a radiation-resistent primary sarcoma of the heart.
