[Primary Cardiac Angiosarcoma with Superior Vena Cava Syndrome]

Area of Science:

• Cardiovascular Pathology
• Surgical Oncology
• Medical Oncology

Background:

• Primary cardiac angiosarcoma is an exceptionally rare malignancy with a historically poor prognosis.
• Early diagnosis and intervention are crucial for managing cardiac tumors, but often challenging due to nonspecific symptoms.

Observation:

• A 34-year-old female presented with facial edema and dyspnea, indicative of potential superior vena cava syndrome.
• Advanced imaging (echocardiography, CT, MRI) revealed a large right atrial tumor.
• Surgical resection and reconstruction with a Gore-Tex patch were performed for diagnosis and symptom relief.

Findings:

• Histopathological diagnosis confirmed angiosarcoma of the right atrium.
• Postoperative treatment with doxorubicin hydrochloride and ifosfamide showed partial efficacy against recurrence and lung metastasis.
• The patient ultimately succumbed to brain metastasis 14 months after surgery.

Implications:

• This case underscores the aggressive nature of primary cardiac angiosarcoma and the limited efficacy of current treatments.
• Multidisciplinary approaches involving surgery, chemotherapy, and advanced imaging are essential for managing this rare condition.
• Further research into novel therapeutic strategies is warranted to improve outcomes for patients with cardiac angiosarcoma.
