| Research Abstract |
Intraoperative evaluation of graft property in coronary artery bypass grafting surgery(CABG) is important to predict the graft patency. We analyzed the waveform of transit time flowmeter in graft using animal CABG model. Fast Fourier transformation was applied to analyze waveform of the graft. Our results indicate that the high frequency area of the Fourier spectrum is important to predict graft patency.
