Health Secretary Jeremy Hunt says local health scrutiny committees in the areas affected by the closures expressed concerns about the review process and the matter was referred to the Independent Reconfiguration Panel (IRP).
"(The IRP) strongly agrees with the case for change. However, the report also concludes that the outcome of the Safe and Sustainable Review was based on a flawed analysis of the impact of incomplete proposals and leaves too may questions about sustainability and implementation.
"This is clearly a serious criticism of the safe and sustainable process.
"I therefore accept their recommendation that the proposals cannot go ahead in their current form and am suspending the review today."
Plans to close three children's heart surgery units were today suspended by the Health Secretary.
Jeremy Hunt says plans to close units in Leeds, Leicester and west London were to be put on hold after an independent review suggested the consultation process was based on "flawed analysis".
The Safe and Sustainable Review, which concluded that Leeds General Infirmary (LGI), Glenfield Hospital in Leicester and Royal Brompton in west London should stop providing paediatric cardiac surgery, has been heavily criticised and campaigners have fought ferociously against closure of the units.
Speaking in the Commons, Mr Hunt said he had asked NHS England to continue with the process of looking into the reorganisation of children's heart surgery and asked them to report back by the end of July.
