Abstract

BACKGROUND:

The purpose of this study was to assess the sequential follow-up results of catheter intervention in Kawasaki disease by use of quantitative coronary angiography (QCA) and intravascular ultrasound imaging.

METHODS AND RESULTS:

Catheter intervention was performed on 23 stenotic lesions in 22 patients (aged 2 to 24 years). Percutaneous balloon angioplasty (PBA) was performed in 4 patients, stent implantation in 7, percutaneous transluminal coronary rotational ablation (PTCRA) in 10, and a combination of PTCRA with stent implantation in 2. A total of 21 lesions (91%) were successfully dilated by catheter intervention without major or minor complications. One patient immediately underwent coronary artery bypass grafting (CABG) surgery because stent implantation failed to resolve his lesion. At 4 to 6 months after catheter intervention, 2 restenotic lesions (9%) were detected by QCA in 2 patients who had undergone PBA, and these patients subsequently underwent CABG surgery. In 6 months to 3 years after catheter intervention, no patients showed evidence of ischemic findings. At 3 to 4 years after catheter intervention, QCA and intravascular ultrasound studies were performed on 15 lesions in 14 patients. Two restenotic lesions (13%) were detected by QCA in 2 patients. One of the 2 had stent implantation and underwent CABG surgery, and the other had undergone PTCRA and underwent re-PTCRA. Thirteen patients demonstrated no ischemic findings at 3 to 8 years after catheter intervention.

CONCLUSION:

Catheter intervention for Kawasaki disease can be accomplished and can be effective in the short term, but the long-term efficacy should be verified by further study.
