- This statement was commissioned as a Multisociety Expert Consensus Systems of Care Document by the American Association for Thoracic Surgery (AATS), American College of Cardiology (ACC), American Society of Echocardiography (ASE), Society for Cardiovascular Angiography and Interventions (SCAI), and Society of Thoracic Surgeons (STS). Expert Consensus Systems of Care Documents are intended to summarize the position of these partnering organizations on the availability, delivery, organization, and quality of cardiovascular care, with the intention of establishing appropriate benchmarks.
- The objective of this project was to provide an update to the previously published consensus 2015 The American Association for Thoracic Surgery (AATS) evidence-based guidelines for the management of ischemic mitral regurgitation (IMR).
- We are very pleased to update The American Association for Thoracic Surgery (AATS) Consensus Guidelines on ischemic mitral valve regurgitation (IMR) (Figure 1). These Guidelines were developed based on the results of published randomized clinical trials, large observational studies, and the expert opinion of the authors. Subsequent to the publication of the 2015 AATS IMR Guidelines,1 the 2-year follow-up results of the Cardiothoracic Surgical Trials Network (CTSN) severe and moderate ischemic mitral regurgitation (MR) trials were published.
- Incorporation of new study results, medications, or devices that merit modification of existing clinical practice guideline recommendations, or the addition of new recommendations, is critical to ensuring that guidelines reflect current knowledge, available treatment options, and optimum medical care. To keep pace with evolving evidence, the American College of Cardiology (ACC)/American Heart Association (AHA) Task Force on Clinical Practice Guidelines (“Task Force”) has issued this focused update to revise existing guideline recommendations on the basis of recently published study data.
- The objective of this project was to establish consensus 2015 The American Association for Thoracic Surgery (AATS) evidence-based guidelines for the management of ischemic mitral regurgitation (IMR).
- The medical profession should play a central role in evaluating evidence related to drugs, devices, and procedures for detection, management, and prevention of disease. When properly applied, expert analysis of available data on the benefits and risks of these therapies and procedures can improve the quality of care, optimize patient outcomes, and favorably affect costs by focusing resources on the most effective strategies. An organized and directed approach to a thorough review of evidence has resulted in the production of clinical practice guidelines that assist clinicians in selecting the best management strategy for an individual patient.
- Transcatheter aortic valve replacement (TAVR) has transformed the care of patients with aortic stenosis. The dissemination of this technology after its approval in the United States in the wake of a pivotal randomized trial1,2 has thus far proceeded in a thoughtful and circumspect manner, guided by a coalition of stakeholders dedicated to the delivery of high-quality, patient-centered care. It is anticipated that a number of transcatheter therapies for mitral regurgitation (MR) will also become available for clinical use in selected patients.
