Purpose Of Review:
Functional mitral regurgitation (FMR) is a common complication of left ventricular dysfunction. It is now recognized as an important clinical entity and an independent predictor of poor prognosis in cardiomyopathy patients. In this review, we provide a comprehensive summary of the pathophysiology, latest imaging modalities, and diagnostic criteria for FMR. Additionally, we discuss the recent literature on the continuously evolving surgical and percutaneous treatment options.
Recent Findings:
The criteria for quantification of FMR on echocardiography were updated and are distinct from organic mitral regurgitation in the most recent American College of Cardiology/American Heart Association 2014 valve guidelines. Furthermore, the evolving role of MitraClip for potential treatment of FMR offers exciting prospects to treat high-risk symptomatic patients.
Summary:
Our review serves to consolidate the current diagnostic and treatment modalities for FMR and provide a contemporary resource for clinicians while treating patients. Additionally, we identify the gaps present in our knowledge of FMR to guide further clinical investigation.
