Noninvasive flow evaluations of coronary artery bypass grafting using dynamic cardiac CT

We aimed to investigate the correlation of graft flow measurements between transit-time flow measurement (TTFM) during coronary artery bypass grafting (CABG) surgery and dynamic cardiac CT after the surgery. Fourteen patients underwent CABG with TTFM and postoperative dynamic cardiac CT; 11 internal...

Sumario:We aimed to investigate the correlation of graft flow measurements between transit-time flow measurement (TTFM) during coronary artery bypass grafting (CABG) surgery and dynamic cardiac CT after the surgery. Fourteen patients underwent CABG with TTFM and postoperative dynamic cardiac CT; 11 internal thoracic artery (ITA) grafts and 15 saphenous venous grafts (SVGs) were included for analysis. Pearsons correlation analysis was performed for the comparisons of the TTFM and cardiac dynamic CT flow parameters. TTFM was not significantly correlated with the CT flow of the ITA grafts (r = −0.23, P = .49), but it had a very strong correlation with the CT flow of the SVGs (r = 0.83, P < .01). In patients who underwent CABG surgery, dynamic cardiac CT enabled quantitative evaluation of SVG flow, with good correlation with TTFM.
