BACKGROUND: The management of mechanically ventilated patients depends on a combination of clinical skills and measurement of physiological parameters.
OBJECTIVES: We evaluated the role of mitral annular plane systolic excursion (MAPSE) in the determination of left ventricular systolic function (LVSF) in mechanically ventilated obese patients.
METHODS: A convenient sample of 60 of 68 obese, mechanically ventilated patients in the intensive care unit were included in the study. Transthoracic echocardiogram MAPSE measurement (averaged from 3 consecutive cycles) on 2 separate days, vs the eyeball ejection fraction (classic clinical method) on 2 separate days, and vs the biplane Simpson (classic research and consultative echocardiogram method) on 2 separate days was obtained. In patients with non sinus rhythm, measurements were collected over 5 to 10 heartbeats.
RESULTS: There was a significant positive correlation between MAPSE and LVSF assessment using the eyeball method and Simpson method (r= 0.89 and 0.87, respectively; P< .001). Mitral annular plane systolic excursion was significantly shorter in duration (P< .001).
CONCLUSIONS: Mitral annular plane systolic excursion is useful, an easier technique, and shorter in duration compared with the eyeball method in the determination of LVSF in mechanically ventilated obese patients.
