Calcified amorphous tumors (CATs) of the heart.

Intracavitary cardiac masses include neoplastic and nonneoplastic masses, which may share overlapping clinical symptomatology, physical examination findings, and or imaging characteristics. Definitive diagnosis of a cardiac mass is usually made on surgical excision and histological examination. In this article, we focus on one of the rare nonneoplastic cardiac mass, namely, calcified amorphous tumors. We present a series of three patients, an 80-year-old female who presented to the hospital for evaluation of a near syncope event, a 69-year-old female who presented for evaluation of palpitations, and a 60-year-old female who presented for evaluation of shortness of breath, who were found to have calcified amorphous tumors. We have also provided a relevant review of the literature on this topic.
