 Best practice standards for mitral repair services

Criteria
ACTA, Association of Cardiothoracic Anaesthetists; BSE, British Society of Echocardiography; EACTA, European Association of Cardiothoracic Anaesthesiologists; EAE, European Association of Echocardiography; NBE, National Board of Echocardiography; TOE, transoesophageal echocardiography.
A. Surgical training
1.Surgeons performing mitral valve repair surgery should have undergone specific training in mitral valve repair, including participation in established repair workshops
2.Surgical skills laboratories should be available to develop, maintain, and teach surgical technique
B. Intraoperative echocardiography issues
1.Mitral valve repair should be undertaken only with availability of high quality intraoperative TOE
2.Anaesthetists for mitral repair surgery should have expertise in intraoperative TOE and should hold UK (ACTA/BSE), European (EACTA/EAE), or US (NBE) accreditation. Where the intraoperative echocardiography service is provided by cardiologists, they should be similarly accredited
C. Surgery for atrial fibrillation
1.Hospitals should provide surgical ablation of atrial fibrillation
2.Surgeons undertaking mitral valve repair surgery should have expertise in surgical ablation of atrial fibrillation
D. Volume thresholds
1.Surgeons undertaking mitral repair surgery should be doing more than 25 repairs each year
2.Hospitals undertaking mitral repair surgery should be doing more than 50 repairs each year
E. Audit
1.Surgeons undertaking mitral repair surgery should subject their results to regular audit
2.Audit of mitral valve surgery should include an analysis of the mitral procedures stratified by aetiology
3.Audit should include an analysis of mortality, residual regurgitation on discharge, recurrence of regurgitation, and reoperation rates
4.Mortality for isolated repairs on degenerative disease should be less than 1% and five year reoperation rate should be less than 5%.
5.Audit data on results of mitral valve repair should be available to patients and referring cardiologists
F. Cardiology and imaging issues
1.Local guidelines for referral of patients should be available to all cardiologists
2.Hospitals undertaking mitral repair surgery should have at least one designated cardiology consultant with a subspecialist interest in mitral valve disease
3.Validated quantitative echocardiography should be routinely available
4.Patients after mitral repair should have follow up echocardiography before discharge from hospital or at the first postoperative outpatient visit to quantify residual regurgitation
5.Both preoperative and perioperative echocardiography data should be regularly audited to ensure quality control and to provide continuing education
6.Multidisciplinary meetings should be held focusing on mitral repair including discussion of discrepancies between echocardiographic and surgical findings
