[Autotransplantation as optimal technique for recurrent malignant myxoma of left ventricle]

Application of autotransplantation for left ventricular recurrent malignant tumor which was considered to be originating from the posterior leaflet of mitral valve was presented. A patient was 29 year-old-female and underwent the resection of tumor. The tumor was resected en bloc with the mitral valve, and its histology was myxoma. But she was required reoperation two times because of the recurrence of the tumor unfortunately. The tumor was ultimately diagnosed as the myxofibrosarcoma with chondroid differentiation. At the time of the third surgery, the heart transplantation was thought to be only treatment for radicality. While sounding American counterparts on the possibility of the heart transplantation, her condition took a sudden turn for the worse. An autotransplantation technique was applied for the resection of the tumor emergently. As a result, it was impossible to completely resect the tumor because of severe invasion to the left ventricle, and the patient died suddenly on the 75th day after the operation due to fetal arrhythmia. Through this case, heart transplantation should be considered for such a case, but autotransplantation technique allowed to be a life-prolonging in this case. We believe that this technique which will be obtained the excellent operative field could be used for repair of complex cardiac anomalies and rupture of left ventricle and so on.
