Emergency primary cardiac osteosarcoma resection fails to prevent distant metastases and death at 6 months.
Case Report (n=1)
No
Primary cardiac osteosarcoma is an extremely rare malignant tumor that can present with severe congestive heart failure and requires early differentiation from benign tumors for prompt resection.
Indicates poor short-term survival after resection in young adults; leaves open optimal multimodal strategies for this rare tumor.
A primary cardiac malignant tumor is very rare; its prevalence is only 0.002-0.28%. Among most malignant tumors, angiosarcoma, leiomyosarcoma, and mesothelioma occupy the majority. A cardiac osteosarcoma is extremely rare: to our knowledge, only 36 cases have been reported worldwide. We present a 22-year-old case featuring severe congestive heart failure. Hemodynamically the tumor led to significant obstruction of the mitral valve. The patient underwent an emergency resection operation, but multiple metastases occurred. Though the characteristics still remain unclear because of the low prevalence, it is very important that these tumors be distinguished from benign tumors because of early resection operation.

Takeuchi et al. (2007) conducted a case report in Primary cardiac osteosarcoma (n=1). Emergency resection operation was evaluated on Clinical outcome. Emergency resection of a primary cardiac osteosarcoma in a 22-year-old man was followed by multiple distant metastases and death 6 months postoperatively.
