Calcified amorphous tumor (CAT) is a rare and benign
pathology which is composed of calcified nodules on
a background of a degenerative and inflammatory
amorphous fibrous material.[1-3] Although the
pathogenesis of cardiac CAT is unknown, abnormal
calcium-phosphorous metabolism, particularly in
renal failure, is suspected. Differential diagnosis
includes benign/malignant cardiac tumors such as
a myxoma, teratoma, or rhabdomyoma, thrombosis,
and vegetations. Herein, we report a 67-year-old case who underwent mitral valve surgery through a transseptal incision with a favorable outcome. During operation, we observed that the anterior leaflet of the mitral valve and its subvalvular apparatus were calcified and presented as a giant tumor (Figure 1). After resection of the calcified leaflet, the annulus of the mitral valve was reconstructed using a pericardial patch, and the valve was successfully replaced with a mechanical prosthesis.
