简要总结
After induction of anaesthesia a transesophageal echocardiography probe will be introduced by a trained physician into the esophagus of the patient. The 2-dimensional echocardiographic data will be assessed by using mid-esophageal (4 chamber, 2 chamber, and long axis) and transgastric (basal, midpapillary and apical) views. The views will be assessed by the 17-segment Americal Heart Association model and will be scored from 1 to 5 (normokinesis to dyskinesis). The mean of the 17 segments will be taken and a wall motion score will be calculated and higher the wall motion score index, indicates higher the number of hibernating segments. The left ventricular function will be assessed pre and post-revascuarisation by using the modified Simpsons bi-plane method. Thus the impact of surgical revascularisation will be assessed,
