A Clearwater high school athlete discovered he had a rare congenital heart defect after undergoing a heart screening required by his school.Cameron Crider plays football and basketball at Calvary Christian High School. His schoo l required him to have an electrocardiogram (EKG) after a new Florida law took effect in July.Watch report from Julie Salomone Required heart screening finds teen's undiagnosed congenital heart defect"I went with my brother to the EKG screening place. We went to a different school to do that, we walked in. It was really easy, really fast. They hook you up to some monitors," said Cameron.Under Florida's Second Chance Act, all incoming 9th-grade student-athletes and any student in grades 10 to 12 who has never previously participated in an FHSAA-sanctioned sport must get a required heart screening.Cameron said his school took it a step further and required all current athletes to get screened as well. The requirement is intended to find hidden heart conditions."They discovered that he has atrial septal defect (ASD) which just means holes in the heart so there's holes between the chambers of his heart that's causing blood to flow where it should not. That's a congenital defect which means he was born with this and has had it for 15 years, but we had absolutely no clue," said Laura Crider, Cameron's mother.Cameron must have surgery in October to fix the condition. Cameron believes the heart screening potentially saved him from a life-threatening emergency. He said he never had any symptoms."He is so healthy and playing sports and playing multiple sports. He never had any shortness of breath or I'm tired or my heart feels weird or I'm dizzy. I mean all the things that they tell you maybe to look for, none of that really, truly no warning signs at all," said Laura.The organization, Who We Play For, works to eliminate preventable sudden cardiac deaths in young people through affordable heart screenings.Cameron's mother said the organization provided the screening for her son.She also said she's grateful for those who pushed for legislation to require the screenings."I've been able to connect with some parents that really pushed for this legislation and sadly, you know, the reason that they did that is because they lost their kids to sudden cardiac death so we owe an immense gratitude to them," said Laura.Florida became the first state to require the EKG screenings. Cameron believes more states should adapt a similar law."I would like them to take away that the screening should be necessary around the whole country. It's a very experience and they can really save your life because like me, I didn't know anything so I just think that everyone should have to do it and it's really worth it," said Cameron.After surgery, Cameron must rest for at least six weeks, then he can return to playing sports. ...read more read less
