Fig. 3From: Preserved autoregulation of coronary flow after off-pump coronary artery bypass grafting: retrospective assessment of intraoperative transit time flowmetry with and without intra-aortic balloon counterpulsationChanges of mean graft flow during on IABP and off IABP. Graft flow on IABP was more than 5 ml/min greater in 28 (37%) bypass grafts (left), and more than 5 ml/min lower in 20 (26%) bypass grafts (right), and the difference was less than 5 ml/min in 28 (37%) bypass grafts (middle)Back to article page
