Although the Royal Brompton Hospital lost its case in the High Court today, a final decision on the future of its children's heart unit is yet to be made.
Proposals outlined by the NHS would see the number of children's heart units in London cut from three to two.
That would see the Royal Brompton's unit closed - leaving units at only Great Ormond Street and the Evelina Children's Hospital at Guy's & St Thomas' NHS Trust.
But the final decision will not be made until later this year.
