Primary cardiac angiosarcoma with isolated superior vena cava syndrome: a case report

Patients with cardiac angiosarcoma may present with atypical or nonspecific symptoms, such as with our patient presenting with isolated superior vena cava syndrome, and an atypical presentation may further delay the diagnosis. Late presenting cardiac angiosarcoma contributes to a worse prognosis and higher likelihood of metastasis at the time of diagnosis. Treatment typically includes chemotherapy and radiation but surgical excision, alone or in combination with other therapies, can provide the best prognosis. Early detection of cardiac angiosarcoma is crucial for improving outcomes.
