A Calcified Amorphous Tumor from the Aortic Valve to the Tricuspid Valve with Aortic Valve Stenosis

Abstract

We report a rare case of a hemodialysis patient with calcified amorphous tumor (CAT) originating from aortic valve cusp that continues to tricuspid valve, which may be related to aortic annular calcification and aortic valve stenosis. A 79-year-old female with chronic kidney disease on hemodialysis for 16 years was transferred to our hospital with loss of consciousness. Echocardiography revealed aortic valve stenosis and presence of tumor on the aortic valve and tricuspid valve. We suspected the presence of a cardiac tumor or vegetation. We underwent tumor resection of tricuspid valve and aortic valve replacement and coronary artery bypass grafting (SVG-RCA). Pathological findings of the tumor was CAT.
