We have developed a simple technique for establishing high-quality intraoperative fluorescence imaging in off-pump coronary artery bypass grafting. The technique of transaortic injection of indocyanine green is an effective method of achieving clear fluorescence imaging and for evaluating the quality of graft anastomoses. We consider the images obtained with this technique to be equivalent to those obtained by conventional coronary angiography with selective enhancement of the graft.References
