Key result
Simple aspiration of a calcified amorphous tumor in the mitral annulus led to a mobile mass 3 weeks later, requiring surgical removal and folding of the tumor wall to prevent recurrence.
Case Report (n=1)
Simple aspiration of a calcified amorphous tumor in the mitral annulus may lead to early recurrence, suggesting the need for more definitive surgical techniques such as folding the tumor wall.
Simple aspiration of mitral annular calcified tumor risks mobile mass recurrence; leaves open optimal management in hemodialysis patients.
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.

Miyano et al. (2016) conducted a case report in Severe aortic stenosis and calcified amorphous tumor in the mitral annulus (n=1). Simple aspiration of tumor deposit followed by surgical removal and folding of tumor wall was evaluated on Tumor recurrence or mobile mass formation. Simple aspiration of a calcified amorphous tumor in the mitral annulus led to a mobile mass 3 weeks later, requiring surgical removal and folding of the tumor wall to prevent recurrence.
