“…A CCAT is characterized by a calcified nodule in an amorphous background with fibrous degeneration and focal inflammation ( 3 ). Solely calcified cardiac mass without thrombus or inflammation are extremely rare ( 4 ). A past study showed that inflammation does not occur in CCATs in non-ESRD ( 5 ).…”

“…Appropriate screening imaging modalities for cardiac mass include echocardiography, computed tomography (CT), cMRI, and PET-CT; they can be used to make differential diagnoses among myxomas, fibroelastomas, thrombi, and among others. All of these can eliminate the problem of differential diagnoses ( 4 ). Although PET-CT and FDG uptake can provide valuable information about inflammation for the differential diagnoses ( 5 ), histopathology is still needed to make a final diagnosis, especially for CCATs.…”

Primary cardiac calcification is a rare benign mass in patients with end-stage renal disease. A few cases have been reported in the literatures. In this case study, during a routine checkup for hemodialysis, a transthoracic echocardiography on a 19-year-old male showed a cardiac mass in the right atrium that was partially obstructing the tricuspid valve. Cardiac magnetic resonance imaging showed a well-circumscribed, homogeneous “shadow” in the right atrium; it measured 29 × 27 mm, had equal T1- and T2-weighted signal intensities, and was adjacent to the tricuspid valve. According to 18F-fluorodeoxyglucose positron emission tomography combined with computed tomography, there was a dense circular shadow in the right atrium abutting the tricuspid valve, but there was no increase in glucose metabolism. Median sternotomy was performed for the surgical resection of the mass, and a cardiopulmonary bypass was completed. The mass was completely removed. The patient recovered well and was discharged 10 days after the surgery. Histological examination showed that the mass contained multiple calcified nodules. No mass recurrence was found by echocardiography during the 12th-month follow-up.

A cardiac calcified amorphous tumor (CAT) is a non-neoplastic cardiac mass composed of calcified nodules surrounded by amorphous fibrous tissue in a context of degeneration and chronic inflammation. Although CAT cases are increasingly reported, its clinical manifestation remains unclear. We aimed to conduct a narrative review of CAT and identify its clinical characteristics. We conducted a comprehensive literature search using PubMed, with the keyword “Cardiac Calcified Amorphous Tumor” to identify relevant articles. A total of 113 articles published between 1997 and 2022 were retrieved. The clinical features allowing for assess patient background, differences with and without end-stage renal disease (ESRD), symptom-related factors, risk factors for embolism caused by CAT, and features of CAT, such as shape, location, mobility, pathology, and treatment, were statistically analyzed in 106 criteria-matched cases. The mean patient age was 60.2 ± 18.6 years, with 45 men and 61 women. Of the data collected from 21 countries, 52 patients were from Japan. Mobile CAT was more common in the chronic renal failure group. Linear, club-shaped, and spindle-shaped CAT tended to be mobile and more common in the ESRD group as well as located in the mitral valve region. The shape, mobility, location, and underlying mechanism of CAT depended on the presence or absence of ESRD. The risk of embolism was considered high because mobile CAT was more common in the ESRD group, and CAT originated in the mitral valve region. Hence, early diagnosis based on periodic examination in patients with ESRD and aggressive surgical treatment are necessary.
