Abstract

This report presents a bicuspidization technique for unicuspid aortic valve repair. To enhance long-term durability, the native free margin was preserved, and a portion was used to construct a new commissure, thereby minimizing the use of the patch in regions subjected to high mechanical stress. At 6.5 years postoperatively, the valve function remains excellent.
