1. A method of performing aortic valvuloplasty comprising:

  • providing a catheter having a balloon;

    advancing said catheter towards an aortic valve;

    expanding a first region of said balloon to a first maximum inflated diameter so as to contact a patient'"'"'s ventricular outflow tract to reduce downstream migration of said balloon;

    expanding a second region of said balloon to a second maximum inflated diameter so as to hyperextend a patient'"'"'s valve leaflets against an aortic sinus; and

    ,expanding a third region of said balloon to a third maximum inflated diameter that is smaller than said first and second maximum inflation diameter and substantially equal to a diameter of a patient'"'"'s valve annulus so as to prevent dissection of said annulus;

    wherein said third region is located between said first region and said second region.
