All studies excluded patients with signs of left ventricular (LV) dysfunction, but the way additional parameters were used to define AFMR at a more granular level varied across studies: nine studies (75%) used the presence of AF to define their AFMR cohorts, with five (41.2%) requiring a history of AF of &gt;1 year; additionally, the threshold values for the LV ejection fraction differed (45%\u201355%). Isolated mitral annuloplasty was performed in 96.2% of patients. Broad variability was detected in the proportion of patients undergoing the Cox\u2010Maze procedure (range, 17.8%\u201379.5%), pulmonary vein isolation (0.0%\u201366.7%), and left atrial appendage ligation (0.0%\u2013100.0%).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>AFMR remains variably defined in surgical studies, making comparisons across studies difficult.
