A 69-year-old man had been treated with total arch replacement for acute Stanford type A aortic dissection. He had cardiac failure at 9 years after his previous operation. Computed tomography and transesophageal echocardiography showed re-dissection of the aortic root and aortic regurgitation. He was referred to our hospital for surgical treatment. In the second operation, aortic root replacement was performed. Re-dissection of the aortic root at the site of the non-coronary sinus was noted intraoperatively, and intraoperative findings suggested necrosis of the aortic wall related to the use of GRF glue. Care should be taken to ensure proper use of GRF glue. The aortic root replacement using a Freestyle valve provided good hemodynamic function and low thrombogenicity. The use of this valve in this case which had residual dissection of the descending aorta seemed useful because of the excellent hemodynamic function without anticoagulant therapy.
