Figure 2From: Withdrawing intra-aortic balloon pump support paradoxically improves microvascular flowThe effect of IABP on perfused vessel density (PVD) for vessels <20 μm. The perfused vessel density increased significantly, 5.47 ± 1.76 to 6.63 ± 1.90 (P = 0.0039), 10 minutes after IABP switch-off.Back to article page
