1 Intraaortic Counterpulsation During Cardiopulmonary Bypass Impairs Distal Organ Perfusion 
Steinar Lundemoen, MD, Venny Lise Kvalheim, MD, PhD, Øyvind Sverre Svendsen, MD, PhD, Arve Mongstad, RP, Knut Sverre Andersen, MD, PhD, Ketil Grong, MD, PhD, Paul Husby, MD, PhD  The Annals of Thoracic Surgery  Volume 99, Issue 2, Pages (February 2015) DOI: /j.athoracsur Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Mean aortic pressure proximal (Prox-AOP mean) and distal (Dist-AOP mean) to the intraaortic balloon pumping (IABP) and (B) blood flow in the carotid and femoral arteries prior to and during IABP-induced pulsatile perfusion. (C) Mean aortic pressure proximal (Prox-AOP mean) and distal (Dist-AOP mean) to the IABP and (D) blood flow in the carotid and femoral arteries prior to and during nonpulsed cardiopulmonary bypass (CPB) perfusion. Values are given as the mean with standard deviation (error bars). †p < 0.05; ‡p < (within-group, pre-CPB vs 30 min and 180 min CPB).

3 Fig 2 Typical plots of arterial pressure and blood flow with intraaortic balloon pump (IABP)-pulsed cardiopulmonary bypass (CPB) perfusion during 3 seconds. (A) Proximal aortic pressure, (B) distal aortic pressure, (C) carotid artery flow, and (D) femoral artery flow before CPB (black lines). The same variables are shown at 90 minutes with IABP-pulsed CPB perfusion (red lines).

4 Fig 3 Tissue perfusion in the (A) left and (B) right kidney before cardiopulmonary bypass (CPB) and at 30, 90, and 180 minutes during intraaortic balloon pump pulsed (black circles) and nonpulsed (open circles) perfusion. Values given as mean with standard deviation (range bars). †p < 0.05; ‡p < within-group, pre-CPB vs 30 minutes and 180 minutes CPB. *p < 0.05; ***p < between groups, same time point.
