Mitral annular plane systolic excursion for assessing left ventricular systolic dysfunction in patients with septic shock
Authors' conclusion
Septal MAPSE is easily measured at the bedside and might help clinicians to detect left ventricular systolic dysfunction early-especially when myocardial strain measurements are not feasible.
Study context
- Population
- Patients with septic shock
- Participants
- 71 patients
- Comparison
- Septal mitral annular plane systolic excursion (MAPSE) for LV systolic dysfunction
- Septal MAPSE ≥1.2 cmn = 18
- Septal MAPSE <1.2 cmn = 53
- Outcome
- LV systolic dysfunction (LVEF <50%, LVLS greater than −17%, or both)
