Long‐term outcome of transcatheter polytetrafluoroethylene‐covered stent implantation in a giant coronary aneurysm of a child with Kawasaki disease

We report the long‐term outcome of a child with Kawasaki disease (KD), who had a giant aneurysm with stenotic lesions in the right coronary artery, resulting in the transcatheter implantation of a polytetrafluoroethylene (PTFE)‐covered stent at the age of 8. Quantitative coronary angiography analysis later showed the increase of the diameter stenosis at both stent edges for the first 10 months after implantation; however, the stenosis did not develop thereafter. Coronary perfusion was still well maintained at follow‐up coronary angiography 5.5 years after implantation (diameter stenosis was 36.5% at proximal and 37.4% at distal edge, respectively). Although further follow‐up is necessary, the long‐term outcome of a PTFE‐covered stent implantation for a KD patient is satisfactory in this instance. Implantation of a covered stent in a giant aneurysm is considered a promising treatment option. © 2012 Wiley Periodicals, Inc.
