Abstract:
A 61-year-old female presented with right atrial mass during physical examination. Contrast-enhanced left heart echocardiography revealed a mass with the size of 32*23 mm in the right atrium, attached to the atrial septum; there was a certain degree of activity and deformation. MRI showed a mass of about 35*22 mm in the right atrium adjacent to the atrial septum, which was diagnosed with right atrial myxoma. Intraoperative TEE showed that the mass was located in the atrial septum close to the inferior vena cava and spontaneous echo contrast with hyperechoic images within the mass. The lesion was resected under cardiopulmonary bypass. Pathological examination revealed that the filling defect was an atrial septal hematogenous cyst with calcification.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
