Percutaneous transvenous biopsy successfully diagnoses rare right atrial spindle cell sarcoma causing tricuspid stenosis.
Case Report (n=1)
Highlights a rare presentation of right atrial spindle cell sarcoma causing tricuspid stenosis and massive pericardial effusion.
Supports consideration of transvenous biopsy for atypical right atrial masses; leaves open routine use pending multicenter data.
Spindle cell sarcomas of the right atrium are extremely rare primary cardiac tumours with very few cases reported in the medical literature. The prognosis of this malignant neoplasm remains poor due to delay in diagnosis, early metastasis and few available therapeutic options. It responds poorly to chemotherapy and radiotherapy. Surgical excision is the mainstay of treatment. We report a 42-year-old man, who presented to emergency room with dyspnoea and fatigue (New York Heart Association classification II) since 1 month. Transthoracic echocardiogram showed massive pericardial effusion with tamponade. The patient underwent emergency pericardiocentesis; postpericardiocentesis echocardiogram showed large right atrial mass involving the right ventricle and the tricuspid valve causing tricuspid stenosis. Findings were confirmed by cardiac CT scan. Percutaneous transvenous biopsy was carried out which revealed spindle cell sarcoma.

Shewale et al. (2016) conducted a case report in Right atrial spindle cell sarcoma (n=1). Percutaneous transvenous biopsy was evaluated on Diagnosis of spindle cell sarcoma. Percutaneous transvenous biopsy successfully diagnosed a rare right atrial spindle cell sarcoma causing tricuspid stenosis in a 42-year-old man presenting with cardiac tamponade.
