A 61-year-old man had undergone
reconstruction of the ascending aorta for acute aortic dissectioniDeBakey
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.
