Mitral annular plane systolic excursion as a surrogate for left ventricular ejection fraction.
Assessing left ventricular function is a common indication for echocardiography. It generally requires expert echocardiographer estimation and is somewhat subjective and prone to reader discordance. Mitral annular plane systolic excursion (MAPSE) has been suggested as a surrogate measurement for left ventricular function. The aim of this study was to examine the accuracy of MAPSE for predicting left ventricular ejection fraction (EF) on the basis of a large cohort of consecutive echocardiograms. ⋯ MAPSE measurement by an untrained observer was found to be a highly accurate predictor of EF.
