Abstract:
Primary cardiac tumors are uncommon. Malignant neoplasms account for 25%, including 75% of cardiac sarcomas. A 53-year-old female complained of exertional dyspnea and orthopnea. Chest computed tomography revealed a mass within the left atrium. Echocardiography confirmed a bilobed left atrial mass protruding through the mitral valve orifice. The tumor was completely resected and was histologically diagnosed as a high-grade pleomorphic sarcoma. A 13-month follow-up was achieved without any recurrence on magnetic resonance imaging.
