Auld B, et al. - In a cohort of children who underwent primary balloon aortic valvuloplasty (BAV) for congenital aortic valve stenosis (AS) in researchers' centre, associations with freedom from re-intervention (FFI) was analyzed. The factors that were found to be related to freedom from re-intervention included valve morphology and the degree of stenosis and regurgitation immediately post BAV. Overall, balloon aortic valvuloplasty affords an effective primary approach to congenital valvular AS with the potential of avoiding surgical intervention in the majority of patients at all ages.
