Balloon Valvuloplasty for Congenital Aortic Valve Stenosis in an Infant and Children

Percutaneous balloon aortic valvuloplasty (BAV) was performed in 14 patients, including one critically ill infant with congenital valvular aortic stenosis (AS). BAV was effective in 13 patients (except the infant). The peak systolic pressure gradient between the left ventricle (LV) and the ascending aorta decreased from 76.6 ± 21.6 to 29.5 ± 15.3 mmHg (P < 0.001). Follow‐up cardiac catheterization was performed for eight patients between 1 and 3 years (1.6 ± 1.1 years) after BAV. Restenosis was found in only one patient, and the efficacy of BAV continued significantly. Aortic regurgitation developed or increased in severity in 5 of 13 children immediately after BAV. Any other severe complication was not observed.
