title: Primary osteogenic sarcoma of the heart.
abstract: The clinical course of a 17-year-old boy with primary osteogenic sarcoma of the left atrium with partial obstruction of the mitral valve and the right pulmonary veins is described. After operative removal of the tumor, echocardiography documented its rapid recurrence. Despite two subsequent open-heart operations and adjuvant chemotherapy and radiotherapy, the patient died twenty-one months after the initial symptoms. Previous reports of such tumors are reviewed, and technical difficulties of removal are discussed.
