Calcified amorphous tumor of mitral annulus treated by simple aspiration

A 49-year-old woman on hemodialysis was diagnosed with severe aortic stenosis and a growing calcified amorphous tumor in the mitral annulus. Because of the anatomical location, we did not resect the whole tumor, while aortic valve replacement was performed instead aspirated the tumor deposit. However, 3 weeks later, a mobile mass attached to the atrial wall was found with echocardiography. We removed the mass and folded the wall of the tumor inside to prevent calcified amorphous tumor recurrence.
