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 annuloplasty.
Mitral regurgitation occurs when one of the four valves in the heart - the mitral valve - does not close properly, allowing blood to leak backwards. It may lead to shortness of breath and eventually heart failure (where the heart cannot pump enough blood to meet the body's needs). In this procedure, a catheter is inserted into a large vein in the groin or neck and passed through to the heart. A device is placed into a large vein that sits next to the mitral valve to constrict the valve, with the aim of making it close properly.
