Long-term clinical follow-up after rotational atherectomy for coronary arterial stenosis in Kawasaki disease

Abstract

During acute KD, the coronary artery lesions most frequently observed in pediatric Kawasaki disease (KD) patients are giant arterial aneurysms. Severely stenotic calcified lesions appear near the aneurysms when patients reach school age. Traditional balloon catheter treatment of stenotic lesions is hampered by the presence of calcification, which makes balloon expansion difficult. In addition, long-term patency is a problem for bypass surgery. Hence, standard treatment has been medical therapy with restrictions on physical activity. Rotablation has made it possible to safely perform catheterization of lesions in pediatric KD patients for which balloon catheter treatment is not indicated. The effects are maintained over the long term and provide benefits as the child grows and develops.
