Abstract
Shock is a common manifestation of many forms of critical illness.
Although a patient with hypotension can have shock, shock is not
necessarily defined by hypotension. When tissue oxygen requirements are
not met by the circulatory system, be it due to poor myocardial function,
hypovolemia, and/or hypotension, a patient is said to be in shock.
Echocardiography and Doppler ultrasound are the main tools used
to evaluate LV function noninvasively in children with heart disease.
Different techniques have been proposed to assess myocardial function.
Mitral annular plane systolic excursion (MAPSE) represents the
amount of displacement of the mitral annular plane towards the apex and
thus assesses the global change in size of the LV cavity (in the long-axisdirection). 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.
The aim of this study is to assess the value of Mitral Annular
plane systolic excursion as an index of mortality in patients with
shock in PICU.
Our study was carried out on 50 patients admitted to the PICU of
Menufiya University hospital with shock caused by sepsis or Systemic
inflammatory response syndrome (SIRS) from January 2015 to June2015.
Their age was from 3 months to 12 years. 23 were males and 27
were females.
