Development of a Risk Calculator to Predict Sudden Cardiac Death in Children With Hypertrophic Cardiomyopathy

This is a retrospective cohort study of pediatric hypertrophic cardiomyopathy (HCM) patients using chart and registry review methodology. The studies objective is to develop and validate a sudden cardiac death (SCD) risk calculator that is age-appropriate for children with HCM that includes clinical and genetic factors.
