Parents who fought to save the children's heart unit at the Freeman Hospital have called the decision for a further review "insane".
After a four-year campaign to retain children's heart surgery in Newcastle, the government announced in July that the Freeman would be the main regional centre in the north.
The decision meant that the unit at Leeds General Hospital would close as a surgical centre. Two other centres were also due to close, in Leicester and London.
Now the Health Secretary Jeremy Hunt has ordered a further review of the closures, and a panel will report back by the end of February.
