The Third Surgical Intervention for a Case of Recurrent Undifferentiated Pleomorphic Sarcoma of the Left Atrium

Abstract

We report a rare case of primary cardiac undifferentiated pleomorphic sarcoma with invasion to the posterior mediastinum, for which partial resection of the tumor in the left atrium had already been carried out twice. After remission for about three years, recurrence in the atrial wall involving the mitral valve posterior leaflet required a third surgical resection following mitral valve replacement. Jpn. J.
