“…The etiology of the CCATs is unknown (6), but some cases are associated with the hemodialysis in ESED (7)(8)(9)(10)(11). Metabolic disorders of calcium and phosphorus, which are common comorbidities among patients with CKD requiring hemodialysis, may result in calcification deposits in the mass, vascular calcification, and calciphylaxis (12)(13)(14).…”

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.

“…Most of them (9 cases) are associated with ESRD. MAC, a chronic fibrous degeneration of the mitral valve, is reportedly caused by abnormalities of calcium-phosphorus (Ca-PO 4 ) metabolism [ 7 – 9 , 12 ]. MAC has been reported to increase the incidence and mortality of cardiovascular diseases but has not been linked to increased risk of myocardial infarction [ 13 ].…”

Cardiac calcified amorphous tumor (CAT) is an extremely rare benign intracavitary tumor of the heart. It may mimic other cardiac tumors and can present with signs or symptoms of systemic embolization. There are limited data regarding CAT in the literature. We report a case of a 68-year-old woman with a cardiac CAT and mitral annular calcification (MAC), who presented with acute ST-elevation myocardial infarction (STEMI) and occipital stroke. After extensive review of the literature, we believe that this case is possibly the first description of a cardiac CAT presenting with STEMI. The CAT was surgically removed, and the diagnosis was confirmed by histology. The patient tolerated the surgery and reported no events at 6-month follow-up.
