Mr Griselli performed a switch operation on our baby boy 3 days after he was born in 2013. He arrived at the Freeman hospital close to death after being born with a transposition of the great arteries. He received the most sublime and diligent care (this opinion is based upon my own medical experience of 20 years) and was back home with us five days after open heart surgery . This must be a world record by a long way. You go to this childrens' heart unit with high expectations (quote from the internet 'the best children's heart surgeons in the world ') and have care offered to you many multiples higher than your expectations. The whole package here is truly marvellous, from the surgeons, physicians, anaesthetists, intensivists,, the nurses, psychologists, managers. This is truly an extraordinarily well run hospital with marvellous surgeons and a world class team. Thank you.
