Local intra capillary HbO2 was monitored in beating hearts of 14 patients undergoing coronary bypass surgery. The spectra were measured in the epicardium of the left ventricle, supplied by the left coronary artery (LAD). All selected patients suffered form stenosis or occlusion of two to three vessels. The patients suffered from severe angina and showed hypokinesia in the angiography. Micro-light guide fibers with a diameter of 75micrometers were used for monitoring before and after bypass surgery. These light guides were connected to the Erlanger Micro Light guide Spectro Photometer EMPHO for registration. Local measurements were performed in the epicardium of the left ventricle in 25 areas 2.25cm2 each. Integrated gradient fields were plotted for each of the 14 patients before and after bypass surgery. The mean values of HbO2 in the respective areas were calculated and evaluated against the local value distribution.
