A 60-year-old man was found to have a partially calcified right atrial mass during evaluation for atrial flutter. Despite anticoagulation therapy, the lesion persisted and a neoplastic process could not be excluded. Therefore, surgical resection was performed through a right mini-thoracotomy approach. Histopathological examination revealed a chronic organized thrombus with focal calcification and hemosiderin-laden macrophages. The postoperative course was uneventful, and no recurrence was observed during 2 years of follow-up. This case highlights the diagnostic challenge of partially calcified right atrial masses and suggests that a minimally invasive approach may provide a useful option for both diagnosis and treatment in selected patients.<\/jats:p>","DOI":"10.1093\/jscr\/rjag880","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T11:29:23Z","timestamp":1790335763000},"source":"Crossref","is-referenced-by-count":0,"title":["Partially
