Principal cardiac services are expected to be based in Cork, Dublin and Galway.
That's according to the National Review of Specialist Cardiac Services, which has been released by the Irish Times.
The main centres are expected to be based at Cork University Hospital, St James', the Mater, and University Hospital Galway.
However, it was recommended that interventional cardiology services should be 'strengthened' at five regional hospitals.
Those regional hospitals include University Hospital Waterford, where there has been a long running campaign for 24-hr cardiac care.
