Sudden unexpected death in a toddler with Williams syndrome.
We report a toddler with Williams syndrome (WS) complicated by congenital heart disease and a seizure-like episode who died suddenly several hours after uneventful cardiac catheterization. The cardiovascular anomalies and their association with sudden death as well as the clinical neurological and neuropathologic abnormalities identified in WS are delineated and discussed.
