Cardiac surgeon speaks straight from the heart
Baby Ashton with his parents before a heart operation
Our next programme (Monday, 31 October 2011, 19:30 GMT) got to me even before the final edit, simply because it shows the work of .
Baby Ashton is just six-weeks-old as he is taken into the operating theatre.
It's hard not to feel for the parents who entrust the lives of their newborns to the surgeons. As we discover in the show we should not just admire the skills of the doctors but we should understand the immense pressure they are under.
Consultant cardiac surgeon, Leslie Hamilton
As consultant cardiac surgeon Leslie Hamilton admits for the first time on television: "It got to the stage where I couldn't do it anymore."
His skill was never in question, it was a matter of confidence. With only two surgeons trying to keep a children's heart unit running, it meant never really being off duty.
Unusual cases didn't come through often enough for the surgeons to practice particular skills so they became second nature.
"You don't get into the comfortable phase of doing the same operation regularly. Children respond differently, unpredictably"Mr Hamilton now only operates on adults, but was part of so they can be bigger, with more surgeons.
Under one of four options Newcastle's Freeman could close, but even the consultants under threat of losing their own unit on Tyneside say it's best for the service as a whole.
It's a very real stress that these doctors have been under, never mind the sheer concentration needed to operate on a heart the size of a walnut.
Dad hands Baby Ashton over to the medical team
In tonight's film it's difficult not to feel the same sense of fear as Ashton is taken into the operating room.
Yes the surgeons are heroes, but they aren't super-human.
