Entire Circumferential Reconstruction of the Right Atrium Surrounded by Angiosarcoma

Primary cardiac angiosarcomas are frequently found at a large size with infiltration into the adjacent heart structure owing to their asymptomatic characteristics until an advanced stage. Therefore, extensive resection is often required to achieve a good prognosis. We herein report a case of entire circumferential resection of the right atrium surrounded by angiosarcoma and excellent three-dimensional reconstruction of the right atrium.
