Insights
Catheter interventions for Kawasaki disease show promise, especially rotational ablation for calcified lesions. Long-term management requires anticoagulation and collaboration between pediatric and interventional cardiologists.
Area of Science:
- Cardiovascular Medicine
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Clinical experience with catheter interventions for Kawasaki disease has grown over 15 years.
- Coronary artery lesions in Kawasaki disease often present with severe calcifications, complicating treatment.
- Established indications and techniques for catheter intervention in adult Kawasaki disease patients are lacking.
Purpose of the Study:
- To review and discuss catheter interventional treatments for coronary artery lesions in Kawasaki disease.
- To evaluate the efficacy and limitations of various interventional techniques, including balloon angioplasty and rotational ablation.
- To highlight considerations for patient selection, procedural techniques, and long-term management.
Main Methods:
- Review of clinical experience with balloon angioplasty, stent implantation, rotational ablation, and transluminal coronary revascularization.
- Analysis of outcomes based on disease duration, lesion characteristics (calcification), and patient age.
- Consideration of complications such as restenosis and new aneurysm formation.
Main Results:
- Satisfactory acute results for balloon angioplasty are achievable in patients within 6 years of disease onset, but restenosis rates remain high.
- Rotational ablation demonstrates a high success rate, particularly for calcified coronary artery stenosis, making it a suitable option.
- Stent implantation necessitates larger arterial access, limiting its use in younger children; new aneurysms can form with high-pressure balloon angioplasty.
Conclusions:
- Rotational ablation appears to be the most appropriate catheter intervention for Kawasaki disease, especially with calcified lesions.
- Long-term management necessitates anticoagulation or anti-platelet therapy and careful monitoring for new aneurysms.
- Coronary intervention for Kawasaki disease requires specialized techniques and close collaboration between pediatric and interventional cardiologists.
Abstract:
During the past 15 years, clinical experience with catheter interventional treatment in patients with Kawasaki disease, including balloon angioplasty, stent implantation, rotational ablation, and transluminal coronary revascularization, has been gradually increasing. Because the coronary artery lesions in Kawasaki disease involve severe calcifications, the indications or catheter intervention techniques have not been established for adult patients with Kawasaki disease. Satisfactory acute results for coronary balloon angioplasty have been obtained in patients with a relatively short interval from the onset of disease, especially within 6 years; however, the incidence of restenosis after angioplasty is still high. Rotational ablation may be the most appropriate catheter intervention technique for patients with Kawasaki disease. The advantage of rotational ablation is the high success rate, even in patients with calcified coronary artery stenosis. Stent implantation requires larger arterial access and is not possible in younger children. Care should be paid to the detection of newly-formed aneurysms, as the formation of new aneurysms is associated with the use of additional balloon angioplasty using high pressure balloon inflation. Anticoagulation or anti-platelet regimens are essential for long-term management. Coronary intervention in Kawasaki disease requires special techniques and knowledge of cardiovascular involvement. The procedure should be managed under the close collaboration between pediatric cardiologists and coronary interventional cardiologists.
