Tonight our biggest hospital has been told it still needs to make improvements.
Leading doctors say there has been progress at the University Hospital of Wales but the Royal College of Surgeons says there are still problems with patients' access to cardiac surgery across South Wales.
James Crichton-Smith reports.
A year after their damning report into cardiac care standards, the Royal College of Surgeons say that while some aspects have improved, they have wider concerns about patients' access to cardiac surgery across South Wales.
In an effort to address ongoing concerns, Cardiff and Vale University Health Board is investing £2.4 million.
The money will be spent on more nurses, better equipment and increased capacity for more operations.
