Catheter interventional treatment in Kawasaki disease: A report from the Japanese Pediatric Interventional Cardiology
1Department of Pediatrics, Kurume University School of Medicine, Kurume, Japan.
Insights
Catheter interventions show promise for coronary stenosis in Kawasaki disease. Careful technique is needed to prevent complications like new aneurysms.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Kawasaki disease frequently leads to coronary artery aneurysms and stenosis.
- Catheter-based interventions are increasingly considered for managing these complications.
Purpose of the Study:
- To evaluate the current use, efficacy, and outcomes of catheter interventions for coronary artery stenosis in Kawasaki disease patients.
- To identify potential risks and complications associated with these procedures.
Main Methods:
- A nationwide questionnaire survey was conducted among 55 major Japanese institutions.
- Data on patient demographics, procedures performed, success rates, and complications were collected and analyzed.
Main Results:
- 58 procedures were performed in 57 patients, primarily percutaneous transluminal coronary angioplasty (PTCA), rotational ablation, directional coronary atherectomy (DCA), and stent implantation.
- Immediate success rates varied by procedure (74% for PTCA to 100% for PTCRA/DCA).
- Complications included restenosis (24% after PTCA) and new coronary aneurysms, often linked to high-pressure balloon use. Two acute deaths were reported.
Conclusions:
- Catheter intervention represents a viable therapeutic option for coronary stenosis secondary to Kawasaki disease.
- Minimizing acute complications and preventing new aneurysm formation through careful procedural technique are crucial for optimal patient outcomes.
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.
