Long-Term Outcomes of Mitral Valve Repair for Atrial Functional Mitral Regurgitation

Atrial functional mitral regurgitation (AFMR), defined by normal left ventricular function, enlarged left atrium, and a dilated mitral valve annulus, has been a concept discussed for over 10 years. However, there are still no established guidelines for its treatment in the ACC/AHA recommendations. This study aimed to determine the long-term outcomes of mitral annuloplasty as a treatment for AFMR.
