Isabella Janew inquest: Parents' questions 'unanswered'
The parents of a girl who died after surgery at Bristol Children's Hospital say her inquest has failed to provide them with answers about her death.
Isabella Janew, from Gloucester, suffered two cardiac arrests following heart surgery at the age of 16 months.
Returning a narrative verdict, the coroner said sudden collapse and death were complications of her condition.
Her father criticised the inquest saying it was "never going to give us the answers we needed".
Avon coroner Maria Voisin told the hearing at Flax Bourton that while two overdoses of drugs were given to restart Isabella's heart, doctors did not believe this had contributed to her second cardiac arrest and subsequent death.
Isabella died in September 2013 following the procedure to widen a heart valve which her parents were told was "low risk".
Speaking outside court, her father Daniel Janew said he wanted to know what really happened to Isabella in intensive care and in theatre.
He said the family had wanted independent experts to be called to shed light on what had happened
"In our opinion it [the inquest] was never going to give us the answers we needed," he added.
In a statement University Hospitals Bristol NHS Trust said Isabella "unexpectedly" had a cardiac arrest during the cardiology procedure, and a second the next day, but could not be resuscitated
"The coroner had heard from medical and nursing staff who explained how they treated Isabella and the steps they have taken since her death to understand why she died.
"In the extreme situation of Isabella's first cardiac arrest two incorrect doses of resuscitation drugs were given, but the coroner found that these did not contribute to her death," a UBHT spokeswoman said
"The trust has... taken steps to minimise the likelihood of overdoses happening again in cardiac arrest situations."
