Abstract
Williams syndrome is a complex syndrome comprising developmental abnormalities, craniofacial dysmorphic features, and cardiac anomalies. The most common cardiac anomaly is supravalvular aortic stenosis. We report a case of a 6-year-old girl with Williams syndrome who presented with decompensated heart failure due to ischemic cardiomyopathy. Her only significant cardiac anomaly was severe stenosis of the left main coronary artery. She subsequently died despite surgical revascularization. Isolated coronary anomalies are rare in Williams syndrome but should be considered especially in the presence of heart failure or ischemia.
