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 mitral valve leaflet repair for mitral regurgitation.


Mitral regurgitation occurs when the mitral valve does not close properly, allowing blood to leak backwards. This can lead to shortness of breath and the heart may be unable to pump enough blood to the rest of the body. During percutaneous mitral valve leaflet repair, a catheter is inserted through the skin via a large vein in the groin or neck and passed through to the heart. The two leaflets of the mitral valve are partially clipped or sewn together to reduce the amount of blood leaking backwards.
