WORK is underway to “enhance” children’s heart services while an investigation continues into the death of three babies at the former Yorkhill Hospital.

NHS Greater Glasgow and Clyde is carrying out an internal review into paediactric surgery after three infants died in one month earlier this year after being treated for a rare condition, Hypoplastic Left Heart Syndrome.

A spokeswoman for the board said the review is looking at a range of clinical factors from diagnosis to anaesthesia and that work had already got underway to enhance services.

All cases of Hypoplastic Left Heart Syndrome in Scotland are continuing to be treated at Evelina Children’s Hospital in London, while the infant deaths are reviewed.

Surgeons in Glasgow started treating cases of the rare condition, four years ago. It is considered one of the most difficult to treat.

The National Services division is also carrying out an external review on behalf of Scottish ministers. The results are due to be published at the end of January next year.

The health board said previously that survival rates within the paediatric heart unit continued to remain within set predicted levels. Reviews are standard procedure when clusters of deaths are recorded in a surgical centre.

Yorkhill services have now moved to the new Royal Hospital for Sick Children at the Queen Elizabeth University Hospital.

A spokeswoman for NHSGGC said: “The internal review of paediatric cardiac surgery is ongoing with work in progress to enhance the current service.

“The review is looking at a range of things to enhance the service including individual steps in the patient’s journey through diagnosis to treatment to follow up journey.

“The service has moved into a state of the art facility and we seek to use it to its maximum potential.”

NHS GGC is responsible for about 300 paediatric cardiac surgical cases annually.

Around 15 years ago, a decision was made to centralise children’s congenital heart services in Glasgow.

Children’s heart surgery in the UK has been under intense scrutiny since the 1990s after high death rates were uncovered at Bristol Royal Infirmary.
