1.1 Current evidence on the safety and efficacy of percutaneous mitral valve leaflet repair for mitral regurgitation is adequate to support the use of this procedure, in patients for whom open surgery is contraindicated following risk assessment, provided that standard arrangements are in place for clinical governance, consent and audit. Find out what standard arrangements mean on the NICE interventional procedures guidance page.
1.2 Patient selection should be done by a multidisciplinary structural heart team, typically including an interventional cardiologist, an expert in transoesophageal echocardiography, an expert in heart failure, a cardiac anaesthetist, a cardiac surgeon and a specialist nurse.
1.3 Percutaneous mitral valve leaflet repair for mitral regurgitation should only be done in specialised centres with access to both cardiac surgical and vascular surgical support in case emergency treatment of complications is needed.
1.4 This procedure should only be done by clinicians with specialist training and supervision by an experienced mentor for at least the first 20 procedures.
1.5 Clinicians should enter details about all patients having percutaneous mitral valve leaflet repair for mitral regurgitation onto the National Institute for Cardiovascular Outcomes Research database.
