Key result
Right mini-thoracotomy achieves complete resection and diagnosis of calcified right atrial thrombus without recurrence.
Why the study?
Partially calcified organized thrombi of the right atrium are rare and may mimic cardiac tumors, complicating preoperative diagnosis.
Case Report (n=1)
No
Minimally invasive right mini-thoracotomy provides a safe and effective method for both the definitive diagnosis and complete treatment of partially calcified right atrial masses that mimic cardiac tumors.
Right mini-thoracotomy may aid diagnosis and resection of ambiguous calcified right atrial masses; leaves open generalizability and optimal strategy.
Partially calcified organized thrombi of the right atrium are rare and may mimic cardiac tumors, making preoperative diagnosis challenging. 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.

Taguchi et al. (2026) conducted a case report in Partially calcified organized thrombus of the right atrium (n=1). Surgical resection via right mini-thoracotomy was evaluated on Definitive diagnosis and clinical outcome (recurrence/complications). Surgical resection via a right mini-thoracotomy successfully provided definitive diagnosis and complete treatment of a partially calcified organized right atrial thrombus with no recurrence over 2 years.
