Bristol Children's Hospital is to reduce the number of heart operations carried out after a formal warning over staffing levels on its cardiac unit.
It follows complaints by parents and a spot inspection by the regulator, the Care Quality Commission.
Inspectors found there weren't enough qualified, skilled or experienced staff and patients were being put at risk.
Six families are currently pursuing legal action against the hospital's trust after their children underwent heart surgery at the hospital.

The head of the trust which runs Bristol Children's Hospital says he's very disappointed by the findings of the CQC.
The Care Quality Commission has issued a formal warning to University Hospitals Bristol NHS Foundation Trust in relation to staffing levels on a cardiac ward at Bristol Royal Children’s Hospital.
The trust had been failing to meet three essential standards of quality and safety covering staffing levels, staff training and support, and the overall care and welfare of patients. Providers have a legal responsibility to make sure they are meeting all the essential standards.
The CQC warned the trust that it was facing further enforcement action unless it made improvements to staffing levels on Ward 32. The trust has also been told that it must provide a report within seven days setting out how it will meet the other standards. For full report click here:

The CQC made a surprise visit to the hospital last month in response to concerns raised.
