Transcatheter stent implantation to treat aortic coarctation in infancy.

A ten week old girl who had previously undergone a palliative procedure for the hypoplastic left heart syndrome had unrelieved aortic coarctation that did not respond to standard balloon dilatation. Complete relief of coarctation with prompt clinical improvement was achieved with placement of an 8 mm self-expanding stent. Transcatheter stent implantation may have a role in selected patients with aortic coarctation.
