This study's objective was to test the hypothesis that transesophageal echocardiography (TEE)–based mitral annular plane systolic excursion (MAPSE) measurement is useful in perioperative settings to detect left ventricular (LV) systolic dysfunction in patients undergoing off-pump coronary artery bypass grafting (OPCAB). Retrospective observational study. Tertiary-care level hospitals. The study comprised 116 patients undergoing OPCAB to obtain cutoffs of MAPSE to detect LV dysfunction. These cutoffs were validated in another 105 patients from 2 other institutions. None. In 116 patients who had undergone OPCAB during the study period with TEE monitoring, MAPSE was measured post hoc at the lateral and septal mitral (and average) annulus using the software tool M.mode.ify (http://www.ultrasoundoftheweek.com/M.mode.ify). Receiver operating curves were constructed to obtain cutoff values of MAPSE at the lateral and septal (and average) annulus of the mitral valve to predict LV systolic dysfunction, which was defined by an ejection fraction
