[Repented Bentall operation for the case of aortitis with totally calcified ascending aortic allograft].

A 49-year-old male underwent re-do root Bentall operation with aortic allograft for the prosthetic valve detouchment due to aortitis syndrome 15 years ago (reported in 1998). He was presented with the hemolytic anemia due to severe aortic stenosis. The totally calcified aortic allograft was found by the computed tomography and chest X-ray. The allograft severely migrated to the sternum was approached by re-sternotomy under the circulatory arrest following the establishment of cardiopulmonary circulation and the 2nd-re-operation of root replacement was performed with composite graft with mechanical heart valve. He was discharged on foot on the 46th postoperative day. A tight follow-up is necessary for such a case of aortitis syndrome.
