ORLANDO, Fla. (AP) — A medical examiner says a central Florida high school student who died after collapsing at a lacrosse practice had a rare heart defect.
The Orange County medical examiner’s office reported Wednesday that an artery was connected to the wrong part of 17-year-old Daniel Valenson’s heart. The Orlando Sentinel (http://thesent.nl/rF95Bm  ) reports that the condition is usually fatal in the first year of life, unless corrected surgically. But officials say it’s possible for it to go unnoticed for years before a person suddenly dies.
The Orange County Sheriff’s Office reports that Valenson was practicing with his team Monday at University High School. When he went to the ground, coaches checked on him and found him in distress. He was taken to a nearby hospital in critical condition. Valenson died the next day.
