Grandmother died after heart valve inserted upside down itv.com

A grandmother died after a heart valve was put in upside down during routine surgery, causing massive internal bleeding.

The operation caused irreversible damage to Sheila Hynes' heart and she never came round from surgery.

A second operation to try and get her heart working failed and the 71-year-old died in intensive care a week later.

Newcastle Upon Tyne Hospitals NHS Foundation Trust, which runs the Freeman Hospital where the operation was carried out, has admitted that the error caused Ms Hynes' death.

Consultant surgeon Asif Raza Shah who led the operation still works at the trust.
