A 51-year-old man, with an abnormal shadow on chest X-ray film, was found to have a right-sided aortic arch with mirror-image branching and Kommerellfs diverticulum. Neither congenital heart anomalies nor vascular ring was observed. We performed descending aorta replacement with a HemashieldTM 24-mm graft, because the trachea and esophagus were compressed by the diverticulum, and to eliminate the risks of aneurysmal change or rupture. The operation was performed through right thoracotomy, and with total CPB under deep hypothermic circulatory arrest. The patient was discharged on the 18th postoperative day. This is rare adulthood case of right aortic arch with Kommerellfs diverticulum and no anomalies in the heart.
