The trust involved in the death of four-year-old Sean Turner at Bristol Royal Hospital For Children has apologised to the family.

The Warminster youngster died in March 2012 from a brain haemorrhage after previously suffering a cardiac arrest – six weeks after he underwent vital corrective heart surgery there.

At the end of a two-week inquest today, Avon coroner Maria Voisin, recording a narrative verdict, said the evidence had raised concerns about more deaths in the future.

Sean's parents, Yolanda and Steve Turner of Cuckoos Nest Lane, spoke of their disappointment 

Robert Woolley, of University Hospitals Bristol NHS Foundation Trust, said after the inquest: "My deepest sympathies are with Mr and Mrs Turner and their family.

"The coroner has heard that their son Sean was born with a very rare and complex heart condition and was undergoing a procedure which carries a known risk of death.

"But the inquest has also highlighted some missed opportunities in the care we gave to Sean when managing his post operative complications and shortcomings in our communication with the family.

"I would like to offer my sincere apologises to Mr and Mrs Turner to the additional distress that we have caused them in relation to Sean's death.

"We are always improving our services and we have made significant changes since Sean was on the ward in early 2012.

"Through medical advances, we are able to treat children today who in previous decades would simply not have survived with the condition they were born with.

"While we aim to make these specialist procedures as safe as possible they continue to carry risks.

"Despite Sean's very sad death, our outcomes are comparable to other national centres for this type of surgery.

"We will of course continue to reflect in Sean's death, the coroner's conclusion and the evidence heard over the last seven days, and we will ensure we have identified all possible lessons for future care of children like Sean."
