OBJECTIVE: To assess the current status of catheter intervention in Kawasaki disease and to evaluate its efficacy and outcome. STUDY DESIGN: A questionnaire was sent to 55 major institutions in Japan. RESULTS: A total of 58 procedures in 57 patients were reported. The median age at the time of intervention was 12.1 years. The procedures included percutaneous transluminal coronary angioplasty (PTCA; n = 34), percutaneous transluminal coronary rotational ablation (PTCRA; n = 13), directional coronary atherectomy (DCA; n = 4), and stent implantation (n = 7). The immediate success rate was 74% for PTCA, 100% for PTCRA, 100% for DCA, and 86% for stents. The interval from the onset of disease to intervention in successful PTCA (n = 25) was significantly shorter than that in unsuccessful PTCA (n = 9). Restenosis after PTCA was observed in 24%. Development of new coronary aneurysms was reported in 3 patients for PTCA, 2 for PTCRA, 3 for DCA, and 1 for stents. Except for the DCA, all new aneurysms were associated with the use of high-pressure balloon inflation. Two deaths were reported as acute complications. CONCLUSIONS: Catheter intervention is a promising therapeutic strategy in the management of coronary stenosis caused by Kawasaki disease. Care should be paid to avoid acute coronary arterial complications and the development of new coronary aneurysms.
