Florida Law Uncovers Life-Threatening Heart Defect in Athlete

A Florida high school sophomore, Cameron Crider, learned he had a serious heart condition, an atrial septal defect (ASD), thanks to a new state law. The Second Chance Act, effective July 1, 2026, mandates electrocardiogram (ECG) screenings for students in grades 9-12 participating in interscholastic athletics. Crider, who played football and basketball, had no symptoms and was unaware of his condition until the ECG, which identified the opening in his heart's upper chambers.

Undiagnosed ASD can strain the heart and lungs, potentially leading to pulmonary hypertension, heart failure, or stroke. Crider's mother expressed shock, noting his rigorous athletic participation without any fatigue or shortness of breath. He is scheduled for corrective surgery in October and anticipates resuming sports next season. Experts emphasize that while the American Heart Association does not currently recommend mandatory ECGs for all athletes, such screenings can be vital, as up to 80% of young athletes experiencing sudden cardiac arrest have no prior warning signs.
