 INTRODUCTION:MAPSE represents the amount of displacement of the mitral annular plane towards the apex and thus assess the global change

in size of the LV(left ventricle) cavity ( in the long–axis direction). Thus, it can be interpreted as the volume change during ejection and therefore a
close association between the long–axis shortening and ejection fraction (EF) has been suggested in different patient groups with normal or reduced
LV function.
BACKGROUND:Reduced MAPSE reflects impaired longitudinal function and thus provides complementary information to ejection fraction
(EF), which represents the global result of both longitudinal and circumferential contraction1. Reduced long–axis deformation results from
dysfunctional or stressed longitudinal myofibers due to ischaemia, fibrosis, or increased wall stress.MAPSE has been suggested as a surrogate
measurement for LV function.
METHODS: Prospective analysis of 111 patients came to our OPD by two–dimensional transthoracic echocardiography was carried out.
MAPSE and ejection fraction measured by qualitative visual inspection, M–mode (medial and lateral septal annulus), modifiedSimpson‘smethod
.MAPSE was compared against ejection fraction by modified Simpson‘susing Standard statistical analysis.
RESULTS:There are 90 male and 21 femalepatients included in these studies. These patient are divided in to four category based on ejection
fraction which includes, 1) EF less than 30 % EF(N=20) 2)EF 30–40 %(N=27) 3)EF 40–50%(N=10) 4)more than 50 %(N=54).MAPSE of the
groups are 1)less than 30%–mean MAPSE=5.3, 2)30–40%EF mean MAPSE =7.52, 3) 40–50 %EF mean MAPSE=9.8 4)more than 50 % EF mean
MAPSE=14.5. P value is 0.001.MAPSE cutoff value of less than or equal to 5 provided the best balanced predict EF <30%.From these study
MAPSE less than 14 suggested presence of LV dysfunction.
CONCLUSION:MAPSE measurement is still especially helpful to evaluate LV systolic function in case of poor sonographic windows, since
good imaging quality is required for most of the modern echocardiographic techniques.
