Key result
64-slice MDCT demonstrated a 95% overall diagnostic accuracy, 97% specificity, and 98% negative predictive value for detecting significant bypass graft stenosis or obstruction in the early postoperative period.

Can 64-slice MDCT accurately evaluate coronary artery bypass graft patency in the early postoperative period compared to conventional coronary angiography?
The study aims to evaluate the utility of non-invasive 64-slice MDCT for assessing CABG patency in the early postoperative period.
Supports noninvasive MDCT for early post-CABG graft assessment; leaves open need for larger prospective validation.
Coronary artery bypass graft surgery (CABG) has been widely used for patients with multivessel coronary artery disease.The post-operative patency of the bypass graft is important to predict the clinical outcome (1-3).Postoperative myocardial infarction is a rare, but potentially severe complication after CABG.So, the early recognition of the failure of a bypass graft on the early postoperative imaging is necessary to evaluate the quality of the surgical anastomosis and the graft patency (4, 5).Conventional coronary angiography (CCA) is currently the standard diagnostic modality that's used to assess the status of bypass grafts.However, it is an invasive

Jeong et al. (2009) conducted an observational in Coronary artery disease post-CABG (n=24). 64-slice MDCT vs. Conventional coronary angiography was evaluated on Diagnostic accuracy for detecting significant stenosis or obstruction of bypass grafts. 64-slice MDCT demonstrated a 95% overall diagnostic accuracy, 97% specificity, and 98% negative predictive value for detecting significant bypass graft stenosis or obstruction in the early postoperative period.
