A 49-year-old woman with symptomatic pulmonary stenosis underwent percutaneous balloon valvuloplasty. In Panel A a guide wire has been advanced into the left pulmonary artery, and a contrast-filled, catheter-mounted balloon straddles the stenotic pulmonary valve. In Panel B the 25-mm balloon is fully inflated to a pressure of 3 atmospheres, with dilatation of the pulmonary valve, as evidenced by the disappearance of the balloon waist. The transvalvular pressure gradient was reduced from 65 to 32 mm Hg.
