Case of left atrial myxoid sarcoma with lung metastases presented as a cardiogenic shock: a case report and literature review

Cardiac tumors are a rare condition that typically presents with nonspecific symptoms. Among the histologic patterns, myxoid sarcomas are rarely identified and may have a less favorable prognosis. Reporting a case of this type of cardiac tumor can increase awareness about this condition and aid in early diagnosis, potentially leading to better outcomes. CASE PRESENTATION: We are presenting a case of a 41-year-old female with left atrial myxoid sarcoma, which was presented with a cardiogenic shock picture. She underwent surgical excision of the mass and was discharged in good condition. After discharge, she deteriorated and was found to have lung metastases. CLINICAL DISCUSSION: Primary cardiac sarcomas, due to their rarity and poor prognosis, are often diagnosed at an advanced stage of the disease and lack sufficient data to establish a standard course of treatment. The cornerstone of therapy is surgical resection. However, novel therapeutic approaches must be developed. CONCLUSIONS: Primary cardiac tumors should be suspected in adult patients with progressive dyspnea, and a biopsy should also be done to determine the histopathological pattern of the mass and estimate the overall prognosis and outcomes.
