Right atrial blood cyst in elderly patient: the timing of surgery

摘要

A regular check up on a 59-year-old man showed a high carcinoembryonic antigen level in his blood. A computed tomography scan showed tumors in the right atrium. We performed tumor resection successfully. The resected specimen was found to be blood cysts that had developed from the right atrium to the inferior vena cava. Intracardiac blood cysts are generally observed in infants, spontaneously disappear during the first 6 months of life, and are located in the left side of heart and on atrioventricular valves. Therefore, this case is extremely rare. Also, it is worth considering the timing of this surgery.
