Treatment with Intravenous Immunoglobulin (IVIG) prevents coronary artery lesions; although there are some IVIG-resistant cases, combination therapy with corticosteroids and IVIG is one of the recommendations for treatment of these cases. The aim of this study was to compare these three options for treatment of Kawasaki Disease and to evaluate their ability to deal with coronary artery complication of Kawasaki Disease. Materials and Methods A prospective cross- sectional study of hospitalized cases of Kawasaki Disease, conducted in pediatric department of Imam Reza hospital, Mashhad-Iran, during 2013 to 2015 (18 months). Based on demographic and clinical data of these patients, children with high risk of unresponsiveness to IVIG therapy (based on Harada score), were determined and treated with IVIG and corticosteroids- combination initially. Follow-up patients for heart complications were 6 weeks. Results Twenty five patients (89.2%) out of total 28 hospitalized patients in this period of time who fulfilled diagnostic criteria were considered as complete Kawasaki Disease. Coronary Artery Lesions (CALs) were shown in 4 patients during the follow-up period, with high risk in patients with incomplete presentation (33.3% versus 12%, P
