This review of @entity944 in @entity1 previously seen in a pediatric cardiology clinic attempts to identify factors that may have been predictive of @entity944 . The denominator for these factors is unknown. For example, the number of @entity1 with these possible risk factors who have well tolerated @entity943 is not known. Further studies are planned to document the incidence of these factors in @entity1 with similar lesions whom we continue to follow up. The following conclusions can be drawn from the study: More than three-quarters of the @entity1 who died suddenly had severe limitation of activity, @entity299 on chest radiograph or poor hemodynamic status at cardiac catheterization. The majority of @entity1 who died suddenly had an @entity943 in the 12 month period before death. A significant number of these @entity943 developed for the first time in the year before death. The presence of @entity943 was generally related to poor hemodynamic status in @entity1 who died suddenly. Most sudden @entity204 occurred with the @entity1 at rest and only approximately one-quarter occurred during participation in sports. Each cardiac diagnosis had its own specific profile of types of @entity943 Conspicuously absent from the list of diagnoses were @entity1 with a normal heart and @entity1 with @entity3454 .(ABSTRACT TRUNCATED AT 250 WORDS)
