Abstract
Background: Catheter intervention has become one of the promising therapeutic strategies in the treatment of patients with coronary stenosis due to Kawasaki disease. However, long-term follow-up data has not been clarified. Patients and Method: We reviewed multi institutional experiences of this procedure. From 8 institutions, 65 procedures in 55 patients were reported. The procedures included percutaneous transluminal coronary angioplasty (PTCA; n=28), percutaneous transluminal coronary rotational ablation (PTCRA; n=25), and stent implantation (n=12). The immediate success rate was 86% in the PTCA, 96% in the PTCRA, and 90% in the stent. Age at intervention ranged from 1.9 to 22 years (median 14.5 years) and interval from the onset of disease to intervention was 1.7 to 17 years (median 8.7 years). Follow-up coronary angiographies or myocardial perfusion scan were performed 3 months to 4 years after the procedure. Final follow-up period ranged from 4 months to 6 years (median 3.6 years). Results: During this follow-up period, re-stenosis was detected by follow-up coronary angiography in 8 cases of PTCA (29%), in 1 case of stent implantation (8%) and 7 cases of PTCRA (28%). Although progression of neoaneurysm was not observed, resolution of those aneurysms was not also confirmed. Eight patients were transferred to the coronary bypass surgery. Conclusion: Initial result of catheter intervention in this disease is excellent, however, re-stenosis is not rare during the follow-up period. Care should be paid for long-term patency and collaboration with coronary bypass surgery is essential.
