Abstract

Right atrial (RA) myxoma is common; however, RA myxoma after the percutaneous atrial septal defect closure is very rare. To the best of our knowledge, this might be the first reported case of RA myxoma after Amplatzer closure of an atrial septal defect, leading to a pulmonary artery embolism. We removed all the RA mass, occluder and pulmonary embolus and reconstructed the atrial septum successfully. As a result of surgery, there were no other complications as following up.

Keywords: Amplatzer atrial septal defect closure device; Right atrial myxoma.

Figure 1:
(A and B) Transesophageal echocardiography confirmed the presence of an irregular and inhomogeneous mass attached to the occluder’s superior edge, without obvious pedicle. (C and D) Computed tomography angiography showed a large mass in the right atrium and ventricular attaching the occluder edge and more embolic fragment occluding the pulmonary segment artery. (E–G) The right atrial mass, occluder and pulmonary embolus were removed; reconstruction of the atrial septum was done. (H) Myxoma removed from the right atrium and pulmonary artery. (I) The right atrial myxoma and pulmonary embolus with tumour were confirmed by histopathological study.
