Your child could be walking around with a heart condition and you might not realize it. That is exactly what happened to Martha Lopez-Anderson whose 10-year-old son Sean Anderson died almost ten years ago.

“I could cry every day and it’s not going to change what happened," said Lopez-Anderson.

Lopez-Anderson said Sean's heart condition went undetected and there were no warning signs or symptoms.  He was roller blading outside their home and collapsed and died from sudden cardiac arrest.

On Wednesday she showed News 13 inside her son's room.  She showed us a quilt she had made out of his old t-shirts, her favorite painting he created, and showed us pictures of him with loved ones. “It’s very easy as a parent to that has suffered such a loss to go into a very dark place,” said  Lopez-Anderson.

But instead of letting the loss overcome her, Martha and her husband founded the organization Saving Young Hearts. “If something is found and you can do something about it,” said Lopez-Anderson.

October is National Sudden Cardiac Arrest Awareness Month. According to the American Heart Association, 1 in 88 children are born with a heart condition and many cases go undetected or are misdiagnosed.

The AHA says almost 383,000 people have cardiac arrest outside of a hospital every year, and only 11% survive, most likely because they don’t receive timely CPR.

It’s a pain no parent should ever have to endure but this family is hoping to use their pain to help save other lives.  "We would have love to see him graduate and we would have loved to see what he would have become,” said Lopez-Anderson.

This Saturday Saving Young Hearts is hosting a heart screening for youth between 6-18 years old to check for potential heart problems.  The screenings are free, however there is a $25 suggested donations.

The SYH screening will take place on Saturday, October 19, 2013, at the Jewish Community Center located at 11184 S. Apopka-Vineland Road in Orlando.

Pre-registration is required and available at www.savingyounghearts.org

They only have room for 300 kids so space is limited.  As of Thursday night they had about 150 spots filled.

"For years, mothers and fathers who have lost children and organizations concerned about youth safety have offered heart screenings to tens of thousands of students in their local communities," said Martha Lopez-Anderson.  "We're thrilled to be part of this national effort to help avert the senseless and preventable death of our students."
