It's been described as a system stretched to breaking point that's putting the lives of young children at risk.
Last night we heard exclusive interviews from surgeons working inside our children's heart units.
They told us they were frustrated that the results of a decade-long review, which was set up to improve childrens heart services, had been put on hold after the Government ordered an independent review.
Today that review panel was at the Freeman Hospital, in Newcastle.
It looks after youngsters from across our region and is once again fighting for survival.
