Blood and Guts: A History of Surgery - Bleeding Hearts

Series about the brutal, bloody and dangerous history of surgery continues with a look at the development of heart surgery, which produced some extremely reckless experiments. With a family history of heart problems, presenter Michael Mosley takes a personal interest in these pioneers, who teetered on the scalpel-edge between saviour and executioner. Michael has a go at heart surgery, meets a man with no heartbeat and witnesses an operation where the patient is cooled until their brain stops and has all of their blood sucked out.
