mitral annular plane systolic excursion(English)
- refers to the displacement of the mitral valvular plane in the z-direction and reflects left ventricular longitudinal contraction or shortening, which has been attributed to account for about 60% of the stroke volume. A well-known surrogate measurement of left ventricular ejection fraction (MAPSE = 0.9063 - 0.0076*Age + 0.0113*LVEF), expressed as cm. MAPSE contributes approximately 75% and short axis shortening 25% to SV. Both decline with age, but their percentage contributions to SV are unchanged. EF is preserved by the simultaneous decrease in LVEDV and SV
