The guidelines state that the indication for surgery of the ascending aorta in patients with the bicuspid aortic valve is 45 mm or more, but we will examine whether 45 mm is really the cutoff line.
In addition, we examined how unoperated bicuspid valves that have undergone ascending aortic replacement produce changes.
Others
Bicuspid valve patients are prone to ascending aortic enlargement, and the ascending aorta is operated on at the same time. However, the 45mm guideline is based on clinical data from overseas and is not based on Japanese original data. In the present study, we used 10 years of follow-up data of bicuspid valve patients after aortic valve replacement to determine the appropriate diameter of ascending aortic replacement in bicuspid valve patients.
