Key result
Balloon aortic valvuloplasty in neonates with severe aortic stenosis was associated with a 40% rate of repeat valvuloplasty, 19% rate of AVR, and 8% rate of death or transplant over 4.8 years.

Diminished LV function was associated with poor outcomes after neonatal BAV; leaves open whether early risk stratification improves selection for alternative strategies.
Observational (n=48)
No
In neonates undergoing balloon aortic valvuloplasty, lower pre-procedural LV shortening fraction is a significant risk factor for future interventions or death/transplant.
Petit et al. (2012) conducted an observational in severe aortic stenosis (n=48). Balloon aortic valvuloplasty was evaluated on Repeat balloon aortic valvuloplasty, aortic valve replacement, and death/transplant. Balloon aortic valvuloplasty in neonates with severe aortic stenosis was associated with a 40% rate of repeat valvuloplasty, 19% rate of AVR, and 8% rate of death or transplant over 4.8 years.
