Key result
Mechanical aspiration thrombectomy safely and effectively removed a 37 mm × 26 mm malignant right atrial myoepithelial tumor in a 59-year-old woman.
Why the study?
Minimally invasive endovascular procedures are increasingly used for intracardiac masses, but no evidence-based guidelines exist for optimal management of malignant RA tumors.
Case Report (n=1)
Mechanical aspiration thrombectomy can be a safe and effective minimally invasive alternative to surgical resection for the removal of malignant right atrial tumors.

May support aspiration thrombectomy as a minimally invasive option for right atrial masses; hypothesis-generating and should not yet change practice.
BACKGROUND: Minimally invasive endovascular procedures are increasingly used for management of intracardiac masses. Here, we present a case of successful transcatheter aspiration of a malignant right atrial (RA) mass. CASE SUMMARY: A 59-year-old woman with recurrent small cell lung cancer status-post chemotherapy/radiation presented for evaluation of progressively worsening left upper extremity pain and was found to have an irregular echogenic 37 mm × 26 mm mass partially attached to the posterior atrial aspect leaflet of the tricuspid valve. The mass was successfully removed and biopsied, demonstrating malignant myoepithelial disease. DISCUSSION: Treatment strategies generally depend on symptoms and comorbidities. Currently, most intracardiac masses undergo surgical resection; however, literature has demonstrated both mechanical aspiration thrombectomy and surgical resection to have favorable outcomes. TAKE-HOME MESSAGES: No evidence-based guidelines exist for optimal management of malignant RA tumors. In our patient, mechanical aspiration thrombectomy was safe and effective for removal of the intracardiac mass.
