Transient gradient reduction after balloon aortic valvuloplasty is rarely sustained; leaves open its role in severe AS pending prospective data.

Does balloon dilatation of the aortic valve improve hemodynamic gradients in patients with severe aortic stenosis?
Balloon dilatation of the aortic valve for severe aortic stenosis has limited sustained success due to early restenosis, despite initial hemodynamic improvements.
Dancy et al. (1988) conducted an observational in severe aortic stenosis (n=15). Balloon dilatation of the aortic valve was evaluated on Reduction in gradient across the aortic valve. Balloon dilatation of the aortic valve for severe aortic stenosis showed limited success, with only 4 of 11 patients maintaining a >30% reduction in Doppler gradient 1 to 2 days post-procedure.
