title: Right atrial myxoma developing 4 years following patch closure of an atrial septal defect: report of a case.
abstract: We report herein the rare case of a 13-year-old boy in whom a right atrial myxoma developed 4 years following patch closure of an ostium secundum atrial septal defect, at which time no other atrial abnormality had been observed. The myxoma arose from the atrial septum in the area between the orifices of the coronary sinus and inferior vena cava. The suture line was not involved. Gross and histopathological findings were characteristic of atrial myxoma. Atrial myxomas are usually considered to be slow-growing neoplasms; however, this case demonstrates that the initial period of growth may be quite rapid in some cases.
