A Case of Calcified Amorphous Tumor in the Left Ventricular Outflow Tract

Abstract

We report a case of a hemodialysis patient with a calcified amorphous tumor (CAT) located in Left ventricular outflow tract. A 69-year-old female with chronic kidney disease on hemodialysis for 10 years complained about palpitation and chest tightness. Echocardiography and cardiac MRI revealed a mobile mass in the left ventricular outflow tract (LVOT). We had a follow-up 6 months after finding mass. We thought that as the mass had potential for embolism, we should remove it; we performed an operation, tumor resection without harming the aortic valve. Her clinical course was uneventful. Pathological examination showed that the mass contained calcified nodules and fibrotic tissue. These findings showed CAT.
