Combination of drug-coated balloon angioplasty and excimer laser coronary angioplasty ablation for coronary restenosis of Kawasaki disease: A case report.

Coronary aneurysm is a well-known sequela of Kawasaki disease. Although ischemic heart disease often becomes problematic due to coronary aneurysm and severe calcification, there is no consensus on how to treat ischemic lesions in those with Kawasaki disease. We describe a case of successful percutaneous coronary intervention of the restenosis lesion within a coronary artery aneurysm accompanied by Kawasaki disease by using an excimer laser coronary angioplasty ablation technique followed by drug-coated balloon angioplasty. < Patients with coronary aneurysms after Kawasaki disease have a high rate of coronary artery stenoses. As children with Kawasaki disease mature, cardiologists are likely to see increasing numbers of these patients with cardiovascular complications, including intrastent restenosis. A combination of drug-coated balloon angioplasty and excimer laser coronary angioplasty ablation may be an effective strategy for intrastent restenosis lesions near the coronary aneurysm.>.
