Strategy for localized stenosis caused by Kawasaki disease: midterm results of percutaneous transluminal coronary balloon angioplasty in two infants.

We report the midterm results of percutaneous transluminal coronary balloon angioplasty (PCBA) for localized stenosis (LS) caused by Kawasaki disease (KD). Two 2-year-olds, a girl and a boy, underwent PCBA for severe LS of the left anterior descending artery caused by KD. After 4 years, there was no ischemia and no significant restenosis in the target vessels. PCBA provided a good result for early appearing LS caused by KD in two small infants. The 5-years-old boy was the youngest patient to undergo percutaneous transluminal coronary rotablator. Although the postprocedure result was very effective, 1 year later asymptomatic occlusion occurred.
