In a 62-year old woman with arterial hypertension, a left atrial myxoma and a concomitant atrial septal defect, diagnosed intraoperatively, were recognized. The atrial septal defect was not observed pre-operatively by transthoracic and transoesophageal echocardiography with color Doppler. The myxoma was pedunculated and situated on the inferior part of the interatrial septum and moved to the left ventricle in the diastolic phase. The histopathologic finding was consistent with the diagnosis of myxoma.
