    Abstract: A method of repairing an aortic valve includes, in a following order: an aortic wall incision step; an aortic valve forming step; and an aortic wall suturing step. In the aortic wall incision step, an aortic wall is cut so as to expose an aortic valve side in the inside of an aortic duct to an open atmosphere. In the aortic valve forming step, the aortic valve is formed by restricting a distance between commissures disposed adjacently to each other by placing a thread between the plurality of commissures disposed adjacently to each other. In the aortic wall suturing step, the aortic wall cut in the aortic wall incision step is sutured so as to close the aortic wall.
