The results of a review into the future of children's heart surgery at three hospitals in England is expected to be published later today.
Last year, the NHS revealed plans to end surgery at Leeds General Infirmary, Glenfield Hospital in Leicester and the Royal Brompton in west London.
However, after legal challenges and public opposition to the plans, the Health Secretary Jeremy Hunt ordered the review in October.
The Health Secretary said he has "full confidence" in the children's heart surgery unit in Leeds, weeks after operations were briefly suspended over health concerns.
Jeremy Hunt said it would not be long before he would be making decisions on the safe and sustainable review into children's heart surgery, which is looking at centralising the service into fewer, more specialised centres.
The local MP for Pudsey, Stuart Andrew, said the Leeds unit had undergone the greatest scrutiny of all during the review.
Mr Hunt said: "I do have full confidence in the children's heart surgery at Leeds. I know they do an excellent job.
"You will understand that when there are safety concerns they do have to be investigated. But I'm delighted those issues have been resolved and surgery is continuing."
Children's heart surgery at Leeds General Infirmary resumed today, less than two weeks after all operations were abruptly suspended.
Concern had been raised over figures showing a high death rate at the unit but that data was discredited.
Now children are being operated on once again, as Damon Green reports.
The CEO of the Leeds Teaching Hospital NHS Trust has spoken out to reassure families about the children's heart surgery unit's reputation.
A mother from Wakefield, West Yorkshire, has said she is "absolutely thrilled" that the children's heart unit at Leeds General Infirmary is set to reopen.
Jo Lancaster, whose six year old son Toby has undergone two operations on his heart at the unit, said she has never had any doubts about its safety.
Anne Keatley-Clarke, chief executive of the Children's Heart Federation, has said that families affected by the suspension of the children's heart unit at Leeds General Infirmary are "very worried".
Several MPs based in the Leeds area have welcomed the news that the children's heart unit at Leeds General Infirmary is set to reopen.
Roger Boyle, director of the National Institute for Cardiovascular Outcomes Research (NICOR), has told Radio 4's Today programme that the decision to restart the children's heart unit at Leeds General Infirmary needs to be investigated.
Parents have reacted positively to the news that the children's heart unit at Leeds General Infirmary is set to restart.
Jon Arnold, whose daughter Zoe underwent heart surgery at the unit in 2007, said:
A children's heart unit is set to restart at Leeds General Infirmary after being suspended over patient care concerns.
Leeds Teaching Hospitals NHS trust will work with other agencies, including NHS England, the NHS Trust Development Authority and the Care Quality Commission to provide "sufficient assurance" that the unit is ready to reopen.
In a statement, Maggie Boyle, Chief Executive of the Trust, said: “I am extremely confident that this service is safe and effective and should recommence at the earliest opportunity. I want partner organisations to be as confident in the service as I am."
The children's heart unit at Leeds General Infirmary has remained suspended for the past week.
