GLEN ROCK - A group of elementary students from Academy of Our Lady in Glen Rock showed off their big hearts today.

More than 200 kids stuffed heart-shaped pillows as part of "Matthew's Hearts of Hope", a nonprofit that raises awareness about congenital heart defects.

"Congenital heart defects are the No. 1 birth defect," says organizer Marie Hatcher. "Yet there is no awareness. We're not sure why.  More children pass away from congenital heart defects than from all cancers combined.  But again, there is no awareness."

Hearts of Hope was started by the mother of 5-year-old Matthew Hatcher, who has had several open heart surgeries. She's pushing for states to mandate special heart screenings for newborns.

The pillows will be donated to children at Columbia Children's Hospital.
