We present a case of cardiac calcified amorphous tumor, a rare intracardiac non-neoplastic tumor, in a hemodialysis patient. A 72-year-old woman with no history of thromboembolic, malignant, or inflammatory disease presented with dyspnea. Echocardiography revealed a highly echoic, slightly mobile mass with an acoustic shadow originating from the mitral subvalvular apparatus, extending to the left ventricular outflow tract. She underwent surgical resection of the mass through the aortic valve, which was easily excised from the papillary muscle and chordae tendineae. Histopathologic examination revealed nodular calcium deposits on a background of amorphous degenerated fibrin material, consistent with calcified amorphous tumor.
