A film about The Hospital for Sick Children.
The day Victoria was born surgeons made a hole in her heart. Without it she would have died. The arteries to her heart were formed the wrong way round and the hole allowed the blood from them to mix.
Six months later her mother brought her to the Hospital for Sick Children. Now her heart was big enough to have the major seven-hour operation to correct the original defect and make her heart as good as normal. This dramatic operation was filmed by Horizon for tonight's programme about Great Ormond Street, the most famous hospital for children in the world. It's a hospital with unique facilities and unique problems, having to treat the hardest cases which come from all over England and abroad.
