A six-month-old infant presented 10 days after the onset of fever with signs and symptoms of Kawasaki disease. He was treated with intravenous immunoglobulin, heparin, and oral aspirin. His echocardiogram showed giant bilateral coronary arterial aneurysms with a moderate pericardial effusion. Three days later, there were also large thrombuses in both his right and left coronary arteries, as demonstrated on this parasternal short axis echocardiographic view at the level of the aorta (Figure; Abbreviations: Ao = aorta; LCA = main stem of left coronary artery; RCA = right coronary artery; RV = right ventricle). Giant aneurysms of the left (12 millimetres) and right (6.5 millimetres) coronary arteries are seen, with a large thrombus (delineated by horizontal arrowheads) within the lumen of the left anterior interventricular coronary artery. A moving image showing the salient features is posted on the website at www.***
