Percutaneous transluminal coronary angioplasty for coronary artery stenosis in a young patient with long term Kawasaki Disease.

Kawasaki Disease (KD) is an acute, febrile, multisystem disease of children. More severe complications in 15-25% of cases include, the development of coronary aneurysms, ischemic heart disease, and sudden cardiac death. The standard treatment for significant coronary artery stenosis has generally been aortocoronary bypass surgery, although percutaneous transluminal coronary angioplasty (PTCA) has been described in a small number of patients. This report describes a 14 year old boy with a history of KD who developed multiple coronary aneurysms and stenosis. We performed PTCA, which was successful in relieving the stenosis of the left circumflex artery.
