Successful Replacement of the Aortic Valve and Aortic Arch Using a Freestyle Valve for Postoperative Aortic Regurgitation after Reconstruction of Acute Aortic Dissection / 日本心臓血管外科学会雑誌

ABSTRACT

A 61-year-old man had undergone reconstruction of the ascending aorta for acute aortic dissection (DeBakey type I), He had aortic valve regurgitation at 10 months, and cardiac failure at 18 months respectively after his previous operation. Cardiac failure can progress relatively fast in cases of postoperative aortic regurgitation due to redissection, so early surgical intervention should be considered. In this case, redissection of the aortic root at the site of non-coronary sinus was noted intraoperatively, and intraoperative findings suggested necrosis of the aortic wall related to the use of GRF glue. The aortic root replacement using a Freestyle valve was performed, which was followed by arch replacement. The Freestyle valve provided good haemodynamic function and low thrombogenicity. The use of this valve in this case which had residual dissection of the descending aorta might be useful because of the excellent haemodynamic function without anticoagulant therapy and long-term durability.
