title: Usefulness of repeat balloon aortic valvuloplasty in children.
abstract: This retrospective study examines all 15 patients who underwent a second balloon dilation procedure for congenital aortic stenosis to determine its safety and efficacy. The recurrent gradient was significantly reduced, but 4 patients had unsatisfactory gradient relief, 3 of whom had previous surgical valvotomies; therefore, we conclude that repeat balloon aortic valvuloplasty is worthwhile, although third balloon dilations may not be beneficial.
