Patients are dying waiting for heart surgery, according to a leading doctor who has spoken out about delays at Wales' leading cardiac centres.
Powys GP Dr James Wrench, who leads the South Wales Cardiac Network, said those who need operations are supposed to be treated within 26 weeks.
But he said some cannot wait that long and are going private while others are being treated in England instead.
The Welsh government said they are expecting the situation to improve.
Nick Palit reports, followed by a studio interview with Prof Mike Harmer, chairman of the Welsh Health Specialised Services Committee.
