Mitral Regurgitation in 2020: The 2020 Focused Update of the 2017 American College of Cardiology Expert Consensus Decision Pathway on the Management of Mitral Regurgitation.

The recently published "2020 Focused Update of the 2017 ACC Expert Consensus Decision Pathway on the Management of Mitral Regurgitation" provides a framework for the clinical and echocardiographic assessment of mitral regurgitation and describes considerations for the medical, surgical, and transcatheter treatment of mitral regurgitation. The Update provides guidance for clinicians in light of the significant interim developments since the 2017 recommendations, particularly in the areas of secondary mitral regurgitation and transcatheter mitral valve repair. The present review focuses on the aspects of the Update that are most relevant to the cardiac anesthesiologist, with emphasis on the integrated assessment of mitral regurgitation with echocardiography and the indications and considerations for the surgical and transcatheter management of mitral regurgitation.
