Figure 5.

A, A NIR fluorescence image showing in situ right internal thoracic artery (RITA) graft to the left anterior descending (LAD) coronary artery. A composite pedicled radial artery (RA) graft was placed from the RITA to the obtuse marginal artery. Note that no fluorescence was seen in the RITA distal to the RA anastomosis, which was taken down and reconstructed (seen in B). B, NIR fluorescence image taken after revision of RA-to-RITA anastomosis (seen in A). Note fluorescence now seen in distal portion of RITA graft and in LAD coronary artery. (OM, obtuse marginal coronary artery.) (Figure reproduced with permission from Taggart et al.⁴⁹)
