Abstract
ABSTRACT
Background: CABG operation may affect myocardial function by inducing stunning.
Objective: evaluation whether myocardial function is affected by CABG in patients with preserved function.
Methods: : LV function evaluated by LVEF ,LV dimensions ,LA and Aortic root dimension ,Doppler mitral inflow velocities E and A waves and pulsed wave tissue Doppler of mitral annulus.
RV function evaluated by tricuspid annular plane systolic excursion, tricuspid valve inflow E and A waves, tissue Doppler echocardiography at the lateral side of the tricuspid annulus and myocardial Performance Index of RV
Results: Forty patients underwent CABG were included. 18 underwent conventional CABG , while 22 underwent off-pump surgery . Systolic LV function was not statistically significantly affected by CABG . LV diastolic function improved post CABG. Regarding RV function, IMP improved (i.e. values decreased) significantly when comparing the values from before CABG to after CABG. RV systolic function measured via TAPSE was significantly reduced 5 days after CABG and remained so three months postoperatively, and by using TDI systolic and diastolic RV function deteriorated post CABG.reduced TAPSE&RV S՝ with improved RIMP may indicate reduced regional RV function rather than reduced global function.
.
Conclusion: LV function did not deteriorate after CABG in patients with preserved preoperative systolic function. LV diastolic function improved after CABG. RV function reduced post CABG using TAPSE &TDI and improved using RIMP
