Abstract 6076: Long-term Follow-up Results of Percutaneous Catheter Intervention and Coronary Artery Bypass Graft Surgery for Kawasaki Disease: The Nationwide Survey in Japan
The purpose of this study is to clarify the long-term results of percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery for Kawasaki disease (KD) patients. The subject of this survey is KD patients were treated by PCI or CABG surgery in 1,637 hospitals in Japan. For the survey, a questionnaire was sent to pediatric departments in these hospitals, the type of procedure, age at the time of PCI or CABG surgery, gender, acute result, follow-up periods, follow-up results, complication of PCI and CABG surgery. A total of 76 PCI of 67 stenotic lesions (32 in right coronary artery: RCA and 35 in left coronary artery: LCA) in 62 patients (49 males and 13 females) were reported. Median age at PCI was 15.9 years (range: 2.2 to 35) and median follow-up period was 5.2 years (0.2 to 19.0). The types of PCI included percutaneous transluminal coronary angioplasty (PTCA) (n=15), stent implantation (n=11), percutaneous transluminal coronary rotational ablation (PTCRA) (n=49), and direct coronary atherectomy (n=1). Of 76 PCIs, 68 (90%) were successfully dilated. There was no significant difference in immediate success rate among the groups (p=0.7). A total 156 grafts including 12 venous grafts used in CABG surgery (30 RCA and 66 LCA) for 84 KD patients (62 male and 13 female). Median age at CABG surgery was 12.8 years (range: 2.5 to 40) and median follow-up period was 11.5 years (0.1 to 21.2.0). Long term results of PCI and the results of CABG surgery were not differ and both methods are favorable (Figure⇓).
Conclusions Long-term result of PCI and CABG surgery for KD patients is satisfactory. More long-term study and careful follow-up was needed for PCI of KD patients.
