Sudden cardiac arrest and death in the young is a critical public health issue. It occurs in children of any age, sex, racial or ethnic demographic, or socioeconomic status. Importantly, it can affect any individual - athlete and non-athlete alike. Prevention of sudden death in the young is of high importance not only because of the loss of a young life but also because of the substantial impact to families and to society at large. This White Paper summarizes the proceedings of a third national Think Tank on prevention of sudden cardiac death in the young. The Think Tank, which convened on January 11-12, 2024 at Duke University in Durham, NC, was organized and conducted by the Cardiac Safety Research Consortium in collaboration with a broad panel of US and international stakeholders including representatives from the United States Food and Drug Administration, medicine, academia, industry, the military, parents and sudden cardiac arrest/death prevention advocates, and the public. Primary and secondary prevention of sudden cardiac death in youth were discussed in depth with a goal of developing consensus on uniform approaches which could be applied nationally.
