RESUMO
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.

From 1974 through 1991, a total of 583 children with Kawasaki disease were seen at the Hospital for Sick Children, in Toronto, of whom 80 (13.7%) had coronary artery involvement. There were 55 boys and 25 girls, whose mean age at onset was 2.9 +/- 2.5 years, followed for a mean period of 4.0 +/- 3.6 years. Giant aneurysms (maximum diameter > or = 8 mm) were found in 22 children, moderate-sized aneurysms (> or = 4 to < 8 mm) in 44, and dilation lesions (< 4 mm) in 14. Myocardial infarction occurred in 9 (1.5%), all of whom had giant aneurysms. The persistence rate for aneurysms was 72% at 1 year and 41% at 5 years of follow-up. In multivariate analysis, the regression of an aneurysm was significantly related to the severity of coronary artery lesions, initial treatment, and gender. Although > 80% of small or moderate-sized aneurysms regressed within 5 years, giant aneurysms did not regress during the follow-up period. In patients who received immune globulin therapy, coronary lesions tended to resolve more rapidly than in those treated with salicylate therapy alone, because 91% of the lesions in the former were small or moderate. These findings suggest that the severity of coronary artery involvement during the initial stages of Kawasaki disease influences the regression of these lesions, and that immune globulin treatment may improve outcome by reducing the incidence of severe lesions.
