Noninvasive assessment of coronary artery bypass grafts with 64-slice computed tomographic angiography

We evaluated the accuracy of the 64-slice computed tomography (CT) angiography scanner in subjects who were scheduled to undergo invasive angiography for possible stenosis in coronary artery bypass grafts.

It permitted an accurate noninvasive assessment of bypass grafts, even in subgroups of subjects with suboptimal scan conditions, such as those with arrhythmias or higher heart rates.
