Emergency coronary artery bypass grafting for cardiogenic shock due to left main coronary artery obstruction caused by K awasaki disease in a 4‐year‐old boy

We describe the case of a 4‐year‐old boy whose clinical course after K awasaki disease resulted in coronary artery bypass grafting ( CABG ) due to acute myocardial infarction ( AMI ) causing cardiogenic shock. He had developed an ischemic cardiomyopathy due to severe localized stenosis of the left main coronary artery ( LCA ) and went into cardiogenic shock due to AMI on the day before a scheduled operation. He underwent successful emergency CABG within 4 h of MI . Postoperatively his neurological status was intact. This is the first report of a successful emergency CABG in a small child with cardiogenic shock due to LCA occlusion. CABG should be undertaken in small patients when appropriate indications exist, if bodyweight is >10 kg.
