Successful triple coronary artery bypass in a child with multiple coronary aneurysms due to Kawasaki's disease

A 9-year-old girl developed ischemic cardiac symptoms 3 years after she first presented with characteristic manifestations of Kawasaki's disease, namely, high fever, conjunctivitis, lymphadenopathy, macular truncal skin rash, and erythema of both hands followed by desequamation of the skin of the fingertips. This acute illness resolved spontaneously within 2 weeks. Because of progressive and severe anginal symptoms and electrocardiographic signs of myocardial ischemia, she underwent cardiac catheterization and coronary angiography, which demonstrated multiple aneurysms of both right and left coronary artery systems. The two larger aneurysms of the right main and left main coronary arteries were clotted, causing complete occlusion of these vessels. Only collateral branches from the proximal right coronary artery which were supporting the entire coronary circulation, prevented her from having a myocardial infarction. A triple saphenous vein bypass was performed with excellent immediate results. One year later the patient was completely free of symptoms; she was living a normal life and a stress electrocardiogram was entirely normal.
