[II-IPD-01] Balloon valvotomy for critical aortic stenosis
Optimal initial treatment for congenital aortic valve stenosis (AS) in children remains controversial, with multiple single-center studies reporting on short- and mid-term outcomes following balloon aortic valvuloplasty (BAV) and/or surgical aortic valvotomy (SAV). In 2001, a multicenter study from the Congenital Heart Surgeons Society demonstrated that BAV and SAV had similar reintervention and survival rates in neonates with critical AS selected for biventricular repair. Since that publication, several single-center studies have described long-term outcomes post BAV and SAV suggesting improved outcomes following surgical valve repair. This presentation will review the available literature on outcomes in neonatal critical AS stressing the importance of discriminating between critical and non-critical AS when studying outcomes after treatment during the neonatal period.
