ABSTRACT
Myxofibrosarcoma is one of the most rare tumors of the heart. Surgical resection is the principal method of treatment; however, in some cases, radical removal of the tumor is not possible. Here, we present a case of heart transplant in a patient who experienced recurrent myxofibrosarcoma of the left atrium and examine the morphological features of this tumor. A 40-year-old female patient presented for treatment for heart failure of a high functional class. An examination revealed a tumor in the left atrial cavity, which was subsequently surgically removed. Morphological examination revealed an inflammatory myofibroblastic tumor. After 2 years, the patient's tumor recurred. The tumor was removed, and a morphological study again diagnosed myxofibrosarcoma of the heart. A year later, recurrence was again diagnosed. Instrumental examination determined that the tumor had incurred into the mitral valve and possibly spread to the myocardium. Tumor resection was not possible, and the need to perform a heart transplant was determined. The given case contributes to the practical conclusion that heart transplant contributes to an increase in the life expectancy for patients with inoperable cases of cardiac sarcoma.
