Thousands of people from across the South East are expected to join Politicians and Health Activists in taking the campaign for 24-hour cardiac care for UHW to the gates of Leinster House this lunchtime.
An Oireachtas meeting co- hosted by Sinn Fein's David Cullinane and Fianna Fail's Mary Butler will hear from Waterford Consultants and campaigners, as well as family members of Thomas Power, who died of a heart attack while on the way to receive treatment in Cork last month.
Health Minister Simon Harris has said a further review of facilities at University Hospital Waterford will only take place once a mobile lab has been deployed and has run its course.
The provision of additional service is also based on achieving consensus among South Eastern consultants.
The Medical Director of St. Lukes Hospital in Kilkenny says they are very happy with the cardiac service arrangement they have with St. James in Dublin.
Fianna Fail's Mary Butler says medical politics is playing a role.
Sinn Fein's David Cullinane says urgent action is needed to address the deficit in emergency cardiac care in the South East.
The Oireachtas briefing takes place at 1pm Tuesday and WLRfm news will cover it extensively.
