The future of the Leeds Children's Heart Surgery unit will be debated in Parliament later.
The issue is being raised by Pudsey MP Stuart Andrew. The decision was taken earlier this year to end surgery in Leeds, forcing patients in the region to travel to Newcastle or Liverpool for treatment.
Last week, due to a request from councillors in Lincolnshire concerned about the closure of the Leicester unit, the Health Secretary ordered a review into the decision. The move has been welcomed by campaigners.
