**16. Conclusion**

In summary, Kawasaki disease is an important and common systemic vasculitis of childhood, and the advent of intravenous immunoglobulin has significantly reduced, but not removed the risk of abnormal coronary artery development in affected individuals. There have been significant advances in our overall understanding of the condition, although the aetiology remains uncertain. Of concern is the emerging evidence that KD is a risk factor for adult coronary artery disease. Further research into pathogenesis and long term outcomes are required.
