May support advanced CTA for noninvasive post-CABG graft assessment; leaves open need for validation trials versus ICA.
Systematic Review
Does computed tomography angiography improve graft patency assessment and stenosis detection compared to invasive coronary angiography in patients who have undergone coronary artery bypass graft surgery?
Modern multislice CTA offers high diagnostic accuracy for assessing CABG graft patency comparable to ICA, with fewer complications, supporting its use as a first-line non-invasive tool.
Gabriel et al. (2015) conducted a systematic review in Coronary artery bypass graft surgery. Computed tomography angiography (CTA) vs. Invasive coronary angiography (ICA) was evaluated on Graft patency assessment, stenosis detection, radiation exposure and complication rate. Computed tomography angiography detects graft patency and stenosis with high sensitivities and specificities comparable to invasive coronary angiography, while remaining non-invasive.
