Surgical excision and mitral valvuloplasty using autologous pericardium can be a successful and durable treatment for rare calcified amorphous tumors of the mitral valve leaflet.

May support excision for rare mitral leaflet CAT without MAC; leaves open optimal management given Level 5 evidence.
A cardiac calcified amorphous tumor (CAT) localized to the mitral valve leaflet without mitral annular calcification (MAC) is a rare entity. We report a case of a 69-year-old woman with such a condition, who underwent successful excision of the tumor and mitral valvuloplasty using a glutaraldehyde-treated autologous pericardium. During 38 months of follow-up, no recurrence of a cardiac mass has been recognized. This report addresses questions on the surgical indication for CAT, particularly in cases without MAC, and reviews CATs of the mitral valve.

Masuda et al. (2015) conducted a case report in Cardiac calcified amorphous tumor (CAT) localized to the mitral valve leaflet without mitral annular calcification (n=1). Surgical excision and mitral valvuloplasty was evaluated on Recurrence of cardiac mass. Surgical excision of a rare calcified amorphous tumor localized to the mitral valve leaflet without mitral annular calcification resulted in no recurrence during 38 months of follow-up.
