May allow intra-operative identification of non-patent grafts; leaves open whether FFT-guided revision improves CABG outcomes.
Does intra-operative transit-time flow measurement predict 2-week post-operative angiographic patency in coronary artery bypass grafts?
Power spectral analysis of intra-operative flow measurement (FFT ratio) may be a highly accurate method to distinguish patent from non-patent coronary artery bypass grafts in the operating room.
