Nearly 2,000 children and adolescents die from sudden cardiac arrest each year, with student-athletes being at particular risk. That's why Sarasota Memorial Hospital and Johns Hopkins All Children's Hospital Specialty Physicians team up each year to present Cardiac Athletic Screening for Adolescents, or CASA, as an opportunity for parents to have their children evaluated for risk of sudden cardiac arrest, free of charge, and to schedule whatever follow-up care they may need.
