The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on percutaneous fetal balloon valvuloplasty for aortic stenosis.

In accordance with the Interventional Procedures Programme process guide, guidance on procedures with special arrangements are reviewed 3 years after publication and the procedure is reassessed if important new evidence is available.

The guidance was considered for reassessment in January 2013 and it was concluded that NICE will not be updating this guidance at this stage. However, if you believe there is new evidence which should warrant a review of our guidance, please contact us via the email address below.


Congenital heart defects are the most common type of birth defects and include aortic valve stenosis (narrowing), the severity of aortic valve stenosis ranges from mild to severe, severe cases are rare but carry a high rate of postnatal mortality.
