To investigate the accuracy and trending ability of ClearSight (Edwards Lifesciences, Irvine, CA) in patients with reduced ejection fraction (<55%) undergoing off-pump coronary artery bypass graft (CABG) surgery by comparing the ClearSight-derived cardiac index (CICS) with the cardiac index measured with thermodilution using a pulmonary artery catheter.  Bland-Altman analysis showed that the percentage error between CICS and the cardiac index measured with thermodilution was 40.2% and the percentage error between MAPcs and MAP was 24.6%.
