Complications of Kawasaki Disease
ComplicationsAneurysmal enlargement of the coronary arteries, is the most feared complication in a Kawasaki syndrome. 20-24% will develop coronary artery complications if not treated. With IVIG it may come down to 4-5%

The cardiac complications are the most important aspect of the disease. Kawasaki disease can cause vasculitic changes (inflammation of blood vessels) in the coronary arteries and subsequent coronary artery aneurysms. These aneurysms can lead to myocardial infarction (heart attack) even in young children. Overall, about 10–18% of children with Kawasaki disease develop coronary artery aneurysms with much higher prevalence among patients who are not treated early in the course of illness. Kawasaki disease and rheumatic fever are the most common causes of acquired heart disease among children in the United States.
