Right atrial myxoma with atrial septal defect: a case report and review of the literature.
We report the case of a 63-year-old woman presenting with progressive dyspnea of insidious onset culminating in severe central cyanosis. Conventional studies including M-mode echocardiography did not point to the diagnosis. At cardiac catheterization a large right atrial myxoma producing partial dynamic tricuspid obstruction was discovered along with an atrial septal defect with a right to left shunt. After successful surgical excision of the tumor and repair of the atrial septal defect, the patient has been totally relieved of her presenting symptoms.
