In coronary artery lesions after Kawasaki disease, calcified lesions tend to occur 6 years after the onset of Kawasaki disease. Plain Old Balloon Angioplasty (POBA) can be performed effectively and safely for Kawasaki disease coronary artery stenosis even in early childhood, although long-term observation is important because restenosis and new aneurysm formation have been noted after POBA, making it an effective treatment to improve myocardial ischemia.
