Transcatheter polytetrafluoroethylene-covered stent implantation in a giant coronary artery aneurysm of a child with Kawasaki disease--a potential novel treatment.

We report a case of an eight-year-old boy with Kawasaki disease (KD) who had a giant aneurysm with stenotic lesions located in the right coronary artery, and was treated by transcatheter implantation of a polytetrafluoroethylene(PTFE)-covered stent. Follow-up coronary angiography showed good coronary blood flow. To the best of our knowledge, this is the first child with KD who underwent covered-stent implantation in a coronary aneurysm. Although close follow-up is mandatory, because the long-term outcome is unclear, implantation of a covered stent in a giant aneurysm appears to be a promising treatment option.
