Right atrial pseudomyxoma originated from junction between right atrial wall and tricuspid ring annuloplasty

We present diagnostic echocardiography results of a patient with intracardiac mass who had undergone primary ASD closure and tricuspid valve annuloplasty after being diagnosed with atrial septal defect and tricuspid failure. The atrial mass originated from free right atrial wall junction and tricuspid ring annuloplasty. Typical morphology of intracardiac mass which was considered to be myxoma during preoperative period was found to be an organized thrombus.
