Specifically, we will compare the groups based on the mean number of intravenous fluid boluses, mean amount of norepinephrine and epinephrine infusion required, the number of recorded systolic blood pressures < 90 mmHg, and number of CI < 2.0 L/min/m2. We will also compare the number of times the surgeon must reposition the heart for treatment of hypotension, and ascertain whether the ITPR will help patients tolerate the cardiac displacement better, thus decreasing the time required to complete the bypass graft anastamosis. ECG will be monitored intraoperatively for signs of ischemia including ST changes, greater than 1mm depression or elevation. Postoperatively, we will record the need for and amount of diuretic required.
