Conclusion
We report normal values for intraoperative 3D-RV FWS considering a relatively healthy group of onpump CABG patients with an uneventful perioperative course, without the influence of vasoactive therapy or pacing, and without serious complications. Our data demonstrate that TEE-assessed values in anesthetized, and ventilated CABG surgery patients differ compared to reported TTE-assessed values in healthy, awake and spontaneously breathing patients without cardiac disease, but not the large extent as suspected in view of the mixture of procedures and heterogeneity of patient populations considered in other perioperative trials.
