PURPOSE: Provided is an instrumental set for forming the aortic valve, which changes structures of the aortic valve and the circumference thereof so that the aortic valve restores its normal function. CONSTITUTION: The instrumental set for forming the aortic valve is used for treating aortic regurgitation caused by the increase in diameters of the wheel of aortic valve and the ascending aortic junction. The instrumental set comprises an instrument for forming the wheel of aortic valve that has the shape of a strap or ring for fixing the diameter of the wheel of aortic valve to a constant value, and an instrument for forming the ascending aortic junction that has the shape of a ring for fixing the diameter of the ascending aortic junction to a constant value.
