Key result
MDCT coronary angiography successfully evaluates bypass grafts and identifies graft types in post-CABG patients.
Why the study?
Assessment of graft status after CABG surgery is important, and MDCT has emerged as a high spatial resolution cardiac imaging modality to evaluate bypass graft patency.
Can ECG gated MDCT coronary angiography effectively assess coronary artery bypass grafts in post-CABG patients?
Observational (n=30)
No
Can ECG gated MDCT coronary angiography effectively assess coronary artery bypass grafts in post-CABG patients?
MDCT coronary angiography serves as a safe and non-invasive imaging modality for the assessment of coronary artery bypass grafts.
Answers are grounded in this paper and cite their sources.
MDCT may support noninvasive graft assessment post-CABG; leaves open comparative accuracy and clinical adoption pending larger studies.
Background: CABG surgery is the standard care in the treatment of advanced coronary artery disease. Assessment of the status of the grafts after CABG surgery is an important issue. Recently, MDCT has gained rapid acceptance as a diagnostic cardiac imaging modality, allowing assessment of coronary bypass graft patency with high spatial resolution. Aim: Evaluate the role of (MDCT) in assessment of CABG. Patients and methods: In this prospective study, 30 patients after coronary artery bypass graft surgery are included. The 30 patients were examined by ECG gated MDCT coronary angiography in CT unit in radiology department of national heart institute between (October 2018 to April 2019). Results: The study included 30 patients with prior CABG surgery. Mean age was 61 +/- 6.9 years with male gender predominance represented 86 % (26 patients). The evaluable grafts were 75 grafts. The most common used grafts were the venous grafts represented 59 %( 44 grafts) while arterial grafts represented 41% (31 grafts).The most common landing site of arterial grafts was LAD (with incidence 84%), while the most common landing site of venous grafts was RCA(with incidence 39%). Conclusion: MDCT coronary angiography is a potentially safe, non-invasive modality in assessment of coronary artery bypass grafts in post-CABG patients.

Ibrahim et al. (2020) conducted an observational in Prior coronary artery bypass graft (CABG) surgery (n=30). ECG gated MDCT coronary angiography was evaluated on Assessment of coronary bypass graft patency and landing sites. MDCT coronary angiography successfully evaluated 75 grafts in 30 post-CABG patients, identifying 59% as venous grafts and 41% as arterial grafts.
