Adam Cairns, the Chief Executive of Cardiff and Vale University Health Board - which runs the University Hospital of Wales - spoke to ITV News this evening.
He told Jonathan Hill that the findings of the report by the Royal College of Surgeons are "troubling, worrying and unacceptable".
He said the primary problem - of getting patients into the hospital - caused cancellations of planned procedures, and needs to be tackled with a "much more resilient plan" in future.
