The authors report the first case of successful double-balloon valvuloplasty for treatment of severe valvular aortic stenosis at Queen Sirikit National Institute of Child Health, Bangkok, Thailand. The patient was a 7-month-old, 6 Kg weighed infant with the pressure gradient across the aortic valve of 76 mmHg and aortic valve annulus of 10 mm diameter. The procedure was performed under general anaesthesia. The catheterization data revealed left ventricular and ascending aorta pressure of 156/1 and 52/30 mmHg, respectively. After the procedure the left ventricular pressure decreased to 114/0, left ventricular-aortic pressure gradient to 46 mmHg and no significant aortic regurgitation. He was well at 1-month follow-up with the left ventricular-aortic pressure gradient of 12 mmHg and no significant aortic regurgitation.
