A rare case of primary well-differentiated angiosarcoma of the right atrium

摘要

Primary cardiac angiosarcoma is rare in clinic.However,it is the most common malignant tumor in the heart,accounting for 15%-35%of all cardiac tumors.It is a very aggressive disease characterized by high rates of local recurrence and systemic metastases,and it is a poor prognosis.Echocardiography,computed tomography(CT)and magnetic resonance imaging(MRI)are important tools for diagnosing cardiac angiosarcoma and are valuable in guiding surgical resection and in monitoring treatment efficacy.
