Surgical resection of right atrial metastasis causing obstructive shock is linked to longer survival when feasible.
Case Report (n=1)
Metastases of uterine leiomyosarcoma to the heart are extremely rare but can cause obstructive shock, and surgical resection may be associated with longer survival.
Surgical resection may be feasible in select obstructive cases; leaves open survival benefit without controlled evidence.
Uterine leiomyosarcomas are rare tumours, and secondary cardiac metastases are even rarer. We present the case of a 56-year-old ethnic Chinese woman who was being treated with adjuvant pelvic radiation for uterine leiomyosarcoma when she presented with signs of right heart failure and shock. She was rapidly diagnosed with a solid mass attached to the tricuspid valve. Subsequent surgical resection revealed leiomyosarcoma metastasis. Metastases of uterine leiomyosarcoma to the heart are extremely rare, but clinicians should be aware of this phenomenon. Surgical resection, when feasible, can be associated with longer survival.

Nguyen et al. (2012) conducted a case report in Uterine leiomyosarcoma with right atrial metastasis causing obstructive shock (n=1). Surgical resection was evaluated. Surgical resection of a rare right atrial metastasis from uterine leiomyosarcoma causing obstructive shock was performed, which can be associated with longer survival when feasible.
