Abstract

Mitral annular plane systolic excursion (MAPSE), a parameter that can be obtained from transthoracic echocardiography or nuclear magnetic resonance (NMR), is capable of reflecting the longitudinal systolic function of the left ventricle (LV) and may change earlier than the LV ejection fraction (LVEF), estimated by usual methods. Furthermore, it also presents a correlation with global longitudinal strain (GLS), assessed by speckle tracking in two-dimensional (2D) echocardiography. The importance of MAPSE extends to the ease with which it can be obtained and reproduced, especially in patients with poor image quality, for whom LVEF and GLS may be inaccurate. This review intends to clarify the evidence available in the literature on MAPSE, which, despite its applicable usefulness in the context of various heart diseases, is an underused index in clinical practice.
