Randomized Controlled Trial Comparative Study
Sixteen-slice multidetector computed tomography for graft patency evaluation after coronary artery bypass surgery.
To investigate the ability of 16-slice multidetector computed tomography (MDCT) to assess coronary artery bypass graft patency and to detect bypass stenosis by comparison with coronary angiography. ⋯ Sixteen-slice MDCT allows for noninvasive evaluation of coronary bypass grafts patency with high diagnostic accuracy. Assessment of distal anastomotic stenosis was deficient, particularly for arterial grafts, still limited by low resolution or artifacts. Improved accuracy may be obtained by more aggressive heart rate reduction.
