Surgical Valvuloplasty Versus Balloon Aortic Dilation for Congenital Aortic Stenosis: Are Evidence-Based Outcomes Relevant?

BAD yields less gradient reduction, more postprocedural AI, and a shorter interval between initial and subsequent reintervention than does SAV. Our results demonstrate that SAV is safe and effective and that residual gradients and degree of AI are low. After SAV, the need for AVR can usually be delayed until the child is significantly older. The long-term functional stability after SAV is excellent. BAD in comparison is associated with an increased frequency and severity of AI and the need for earlier reintervention and valve replacement. SAV should be offered to all patients beyond the newborn period because it gives superior and longer lasting palliation.
