What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Systolic function (EF) will be measured in both groups Levosemindan and Adrenaline in patients with low ejection fraction (30-40%), undergoing elective on pump Coronary Artery Bypass Graft (CABG).
Time Frame: 24 hour
|
transesophageal echo (TEE) will be continuously used to monitor LV systolic and diastolic function during surgery and recordings will be made simultaneously with hemodynamic measurements.
LV Ejection Fraction In the transgastric mid-papillary view, the echo machine will be switched to M-mode and the following measurements will be taken: o LV end-diastolic diameter o LV end-systolic diameter The machine will then calculate the LV ejection fraction according to Teich's method
|
24 hour
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
LV Myocardial Performance (Tei) Index will be measured in both groups
Time Frame: 24 hour
|
The left ventricle myocardial performance index will be calculated by placing pulsed Doppler sample volume between the anterior leaflet of the mitral valve and the left ventricle outflow tract (LVOT) in the deep transgastric view.
Tei index = (a-b)/b, where (a) = distance between the mitral A wave and E wave, and (b) = distance between the start and end of the LVOT flow)
|
24 hour
|
LV Stroke Volume and Cardiac Output will be measured in both groups
Time Frame: 24 hour
|
The LVOT diameter will be measured in the mid-esophagus long-axis view. Assuming that the LVOT is circular in shape, the LVOT cross-sectional area will be calculated . The velocity time integral (VTI) of LVOT will be determined by pulsed Doppler imaging in the deep transgastric view by tracing the LVOT ejection curve. The stroke volume (SV) will then be calculated as: Stroke volume (cm3) = LVOT cross sectional area x LVOT VTI Cardiac output (CO) will then be calculated as CO = SV x heart rate, and cardiac index (CI) will be calculated as CI = CO/body surface area. |
24 hour
|
LV diastolic function will be measured in both groups
Time Frame: 24 hour
|
In the mid-esophageal four-chamber view, E-wave velocity, A-wave velocity and E/A ratio will be determined by placing the sample volume of pulsed-wave Doppler at the tips of the mitral leaflets.
Using tissue Doppler imaging, e'-wave velocity will be measured at both the lateral and septal mitral annulus, and the average of both measurements will be reported and used in subsequent calculations.
The E/e' index will be calculated
