Dilatation of congenital valvular aortic stenosis using Inoue balloon.

Balloon dilatation of valvular aortic stenosis is often associated with problems of balloon seating across the valve and slippage during performance of dilatation. We describe 2 patients with congenital aortic stenosis who underwent balloon dilatation using the Inoue balloon, which to the best of our knowledge has not been reported earlier. The technique and its advantages and limitations in aortic valve dilatation are discussed.
